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: tpd (CCK to RCO) = 24 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)

• Ordering Information
