HD74HC592

8-bit Register/Binary Counter

Description

The HD74HC592 consists of a parallel input, 8-bit storage register feeding an 8-bit binary counter. Both

the register and the counter have individual positive edge-triggered clocks. In addition, the counter has

direct load and clear functions. Expansion is easily accomplished by connecting RCO of the first stage to

the count enable of the second stage, etc.

Features

•

High Speed Operation: t_pd(CCK to RCO) = 24 ns typ (C_L= 50 pF)

High Output Current: Fanout of 10 LSTTL Loads

Wide Operating Voltage: V_CC= 2 to 6 V

Low Input Current: 1 µA max

Low Quiescent Supply Current: I_CC(static) = 4 µA max (Ta = 25°C)
