Description : SYNCHRONOUS PRESETTABLE BCD DECADE COUNTERS View

General Description
The ’LS160 and ’LS162 are high speed SYNCHRONOUS DECADE COUNTERS operating in the BCD (8421) sequence. They are SYNCHRONOUSly PRESETTABLE for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count output for versatility in forming SYNCHRONOUS multistage COUNTERS. The ’LS160 has an aSYNCHRONOUS Master Reset input that overrides all other inputs and forces the outputs LOW. The ’LS162 has a SYNCHRONOUS Reset input that overrides counting and parallel loading and allows all outputs to be simultaneously reset on the rising edge of the clock.

Features
SYNCHRONOUS counting and loading
■ High speed SYNCHRONOUS expansion
■ Typical count rate of 35 MHz
■ Fully edge triggered

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.

Description : PRESETTABLE SYNCHRONOUS BCD DECADE counter; SYNCHRONOUS reset View

GENERAL DESCRIPTION
The 74HC/HCT162 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT162 are SYNCHRONOUS PRESETTABLE DECADE COUNTERS which feature an internal look-ahead carry and can be used for high-speed counting. SYNCHRONOUS operation is provided by having all flip-flops
clocked simultaneously on the positive-going edge of the clock (CP).

FEATURES
SYNCHRONOUS counting and loading
• Two count enable inputs for n-bit cascading
• Positive-edge triggered clock
SYNCHRONOUS reset
• Output capability: standard
• ICC category: MSI
