Presettable synchronous BCD decade up/down counter

The 74HC/HCT190 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT190 are asynchronously presettable up/down BCD decade counters. They contain four master/slave flip-flops

Synchronous Up/Down Decade,4-bit Binary Counter(Single Clock Line)

The HD74HC190 and HD74HC191 are synchronous, reverside up/down counters. The HD74HC190 is a 4-bit decade counter and the HD74HC191 is a 4-bit binary counter. Synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each o
