HD74HC190 Datasheet - Hitachi Semiconductor

HD74HC190 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 oth.

HD74HC190 Features

* High Speed Operation: tpd (Clock to Q) = 22 ns typ (CL = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Pin Ar
