HD74HC190 Counter Datasheet, Distribuidor, stock y mejor precio

Part Number	HD74HC190
Manufacturer	Hitachi Semiconductor
Title	Synchronous Up/Down Decade/4-bit Binary Counter(Single Clock Line)
Description	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.
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 Arrangement Inputs Data B 1 QB 2 QB QA G B A CK Ripple Clock 16 VCC 15 Data A Inputs 14 Clock 13 Ripple Clock 12 Max/Min 11 Load 10 Data C .
