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.

Description : TTL −4−Bit Binary Counter
NTE-Electronic
NTE Electronics

The NTE7493A is a monolithic 4−bit binary counter in a 14−Lead DIP type package that contains four master−slave flip−flops and additional gating to provide a divide−by−two counter and a three−stage binary counter for which the count cycle length is divide−by−eight. The counter also contains a gated zero reset. To use the maximum count length of this device, the CKB input is connected to the QAoutput. The input count pulses are applied to CKA input and the outputs are as described in the function tables.

Description : 14-stage binary counter
Philips
Philips Electronics

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
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 : MSI Dual binary counter
Philips
Philips Electronics

DESCRIPTION
The HEF4520B is a dual 4-bit internally synchronous binary counter. The counter has an active HIGH clock input (CP0) and an active LOW clock input (CP1), buffered outputs from all four bit positions (O0to O3) and an active HIGH overriding asynchronous master reset input (MR).
The counter advances on either the LOW to HIGH transition of the CP0input if CP1is HIGH or the HIGH to LOW transition of the CP1 input if CP0is low. Either CP0 or CP1 may be used as the clock input to the counter and the other clock input may be used as a clock enable input. A HIGH on MR resets the counter (O0to O3= LOW) independent of CP0,CP1. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.
