Product Introduction

The SN74LS193N is a Synchronous 4-Bit Up/Down Binary Counters with Dual Clock. It consists of 4 T flip flops and other gate circuits.There is a low efficient asynchronous enabling preset (Load) that can preset input data (A/B/C/D) directly to the output.A high efficient asynchronous zero clearing enable control terminal (Clear);With addition and subtraction counting clock control input Count Down and Count Up.It can achieve continuous counting or counting.Multi-chip cascade expansion can be achieved with low-efficient addition overflow carry output flag (Carry) and subtraction overflow carry flag (Borrow).
