Part Name(s) : HD74LS293 HD74LS293P Renesas
Renesas Electronics
Description : 4-bit Binary Counter

4-bit Binary Counter

This counter contains four master-slave flip-flops and additional gating to provide a divide-by-two counter and divide by-eight counter. This counter has a gated zero reset. To use the maximum count length of this counter, the B input is connected to the QAoutput. The input count pulses are applied to input A and the outputs are as described in the appropriate function table.

Part Name(s) : ICM7226ALJL ICM7226BLPL ICM7226A ICM7226B Harris
Harris Semiconductor
Description : 8-Digit Multi-Function Frequency Counter/Timers

Description
The ICM7226 is a fully integrated Universal Counter and LED display driver. It combines a high frequency oscillator, a decade timebase counter, an 8-decade data counter and latches, a 7-segment decoder, digit multiplexer and segment and digit drivers which can directly drive large LED displays. The counter inputs accept a maximum frequency of 10MHz in frequency and unit counter modes and 2MHz in the other modes. Both inputs are digital inputs. In many applications, amplification and level shifting will be required to obtain proper digital signals for these inputs.

Features
• CMOS Design for Very Low Power
• Output Drivers Directly Drive Both Digits and Segments of Large 8 Digit LED Displays
• Measures Frequencies from DC to 10MHz; Periods from 0.5µs to 10s
• Stable High Frequency Oscillator uses either 1MHz or 10MHz Crystal
• Both Common Anode and Common Cathode Available
• Control Signals Available for External Systems Interfacing
• Multiplexed BCD Outputs

Applications
• Frequency Counter
• Period Counter
• Unit Counter
• Frequency Ratio Counter
• Time Interval Counter

Philips Electronics
Description : 14-stage binary counter

DESCRIPTION
The HEF4020B is a 14-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (O0, O3 to O13). The counter advances on the HIGH to LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle flip-flop. A feature of the HEF4020B is: high speed (typ. 35 MHz at VDD = 15 V).

Description : 12-stage binary counter

DESCRIPTION
The HEF4040B is a 12-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (O0 to O11). The counter advances on the HIGH to LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of CP. Each counter stage is a static toggle flip-flop. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.

Description : 7-stage binary counter

DESCRIPTION
The HEF4024B is a 7-stage binary ripple counter with a clock input (CP), and overriding asynchronous master reset input (MR) and seven fully buffered parallel outputs (O0 to O6). The counter advances on the HIGH to LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of CP. Each counter stage is a static toggle flip-flop.
