CD74HCT161M96E4 [Texas Instruments]

These are 4-bit binary counters featuring synchronous counting and loading, with two count enable inputs (PE and TE) for n-bit cascading. The HC161 and HCT161 have asynchronous reset, while HC163 and HCT163 have synchronous reset. They offer balanced propagation delays, low power consumption compared to LSTTL, and wide operating voltage ranges: HC types (2V to 6V) and HCT types (4.5V to 5.5V).
