SN74HC393N Description

Short technical summary and product information.

The SN74HC393N is a dual 4-bit binary counter IC manufactured by Texas Instruments. It contains eight flip-flops and additional gating to implement two independent 4-bit counters within a single package. This device is designed for a wide operating voltage range of 2V to 6V and operates across a temperature range of -40°C to 85°C.

 

Key electrical characteristics include a typical propagation delay of 13ns, a low supply current of 80μA maximum, and an input current of 1μA maximum. The outputs can drive up to 10 LSTTL loads, with a typical output drive of ±4mA at 5V. The counter features asynchronous reset and negative edge triggering.

 

Packaged in a 14-pin PDIP through-hole configuration, the SN74HC393N is suitable for applications requiring compact counter solutions. Its design can help reduce counter package count by up to 50%, improving system density. The device offers direct clear functionality for each 4-bit counter.
