Description : Presettable Binary/DECADE Up/Down COUNTER

General Description
The CD4029BC is a presettable up/down COUNTER which counts in either binary or DECADE mode depending on the voltage level applied at binary/DECADE input. When binary/DECADE is at logical “1”, the COUNTER counts in binary, other wise it counts in DECADE. Similarly, the COUNTER counts up when the up/down input is at logical “1” and vice versa.

Features
■Wide supply voltage range: 3V to 15V
■High noise immunity: 0.45 VDD(typ.)
■Low power TTL compatibility: fan out of 2 driving 74L or 1 driving 74LS
■Parallel jam inputs
■Binary or BCD DECADE up/down counting

Description : Dual DECADE COUNTER

Description
The M74HC390 is an high speed CMOS dual DECADE COUNTER fabricated with silicon gate C2MOS technology.
This dual DECADE COUNTER contains two independent ripple carry COUNTERs. Each COUNTER is composed of a divide by two and divide by five COUNTER.

Description : Synchronous up/down COUNTER, binary/DECADE COUNTER

DESCRIPTION
The HEF4029B is a synchronous edge-triggered up/down 4-bit binary/BCD DECADE COUNTER with a clock input (CP), an active LOW count enable input (CE), an up/down control input (UP/DN), a binary/DECADE control input (BIN/DEC), an overriding asynchronous active HIGH parallel load input (PL), four parallel data inputs (P0 to P3), four parallel buffered outputs (O0 to O3) and an active LOW terminal count output (TC).
Information on P0 to P3 is asynchronously loaded into the COUNTER while PL is HIGH, independent of CP.
The COUNTER is advanced one count on the LOW to HIGH transition of CP when CE and PL are LOW. The TC signal is normally HIGH and goes LOW when the COUNTER reaches its maximum count in the UP mode, or the minimum count in the DOWN mode provided CE is LOW.

Description : LSI Real time 5-DECADE COUNTER

DESCRIPTION
The HEF4534B is a 5-DECADE ripple COUNTER. The binary outputs of the DECADE COUNTERs are time-multiplexed by an internal scanner on four BCD outputs (O0 to O3). The selected DECADE is indicated by a logic HIGH on the appropriate digit select output (OS0: units, 1; OS1: tens,
10; OS2: hundreds, 102;OS3: thousands, 103; OS4: ten thousands, 104).
The binary outputs (O0to O3) and the select outputs (OS0 to OS4) are 3-state controlled via enable inputs EO andEOS respectively, allowing interface with other bus orientated devices. Cascading may be accomplished by using the carry out (TC). The COUNTER is triggered by a LOW to HIGH transition on the DECADE clock (CPA) and is reset by a HIGH level on the master reset (MR).

Description : Synchronous DECADE COUNTER (direct clear)

Synchronous DECADE COUNTER (direct clear)

This synchronous DECADE COUNTER features an internal carry look ahead for application in high-speed counting designs. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs changes coincident with each other when so instructed by the count-enable inputs and internal gating. This mode is operation eliminates the output counting spikes that are normally associated with asynchronous (ripple clock) COUNTERs.

Description : Presettable Binary/DECADE Up/Down COUNTER

General Description
The CD4029BM/CD4029BC is a presettable up/down COUNTER which counts in either binary or DECADE mode depending on the voltage level applied at binary/DECADE input. When binary/DECADE is at logical ``1'', the COUNTER counts in binary, otherwise it counts in DECADE. Similarly, the COUNTER counts up when the up/down input is at logical ``1'' and vice versa.
A logical ``1'' preset enable signal allows information at the ``jam'' inputs to preset the COUNTER to any state asynchro nously with the clock. The COUNTER is advanced one count at the positive-going edge of the clock if the carry in and preset enable inputs are at logical ``0''. Advancement is inhibited when either or both of these two inputs is at logical ``1''.
The carry out signal is normally at logical ``1'' state and goes to logical ``0'' state when the COUNTER reaches its maximum count in the ``up'' mode or the minimum count in the ``down'' mode provided the carry input is at logical ``0'' state. All inputs are protected against static discharge by diode clamps to both VDDand VSS.

Features
Wide supply voltage range 3V to 15V
High noise immunity 0.45 VDD(typ.)
Low power fan out of 2
TTL compatibility driving 74L or 1 driving 74LS YParallel jam inputs

PRESETTABLE BCD/DECADE UP/DOWN COUNTER
PRESETTABLE 4-BIT BINARY UP/DOWN COUNTER

The SN54/74LS192 is an UP/DOWN BCD DECADE (8421) COUNTER and the SN54/74LS193 is an UP/DOWN MODULO-16 Binary COUNTER. Separate Count Up and Count Down Clocks are used and in either counting mode the circuits operate synchronously. The outputs change state synchronous with the LOW-to-HIGH transitions on the clock inputs.
Separate Terminal Count Up and Terminal Count Down outputs are provided which are used as the clocks for a subsequent stages without extra logic, thus simplifying multistage COUNTER designs. Individual preset inputs allow the circuits to be used as programmable COUNTERs. Both the Parallel Load (PL) and the Master Reset (MR) inputs asynchronously override the clocks.
