SN74LS293N

LOGIC, COUNTER BINARY 4BIT, 14DIP.

The SN74LS293N is a 4-bit Binary Counter 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. To use the maximum count length (decade or four-bit binary) of this counter, the B input is connected to the QA output. The input count pulses are applied to input A and the outputs are as described in the appropriate function table.
