HD74HC563/HD74HC573
Octal Transparent Latches (with 3-state outputs)
ADE-205-509 (Z)
1st. Edition
Sep. 2000
Description
When the latch enable (LE) input is high, the Q outputs of HD74HC563 will follow the inversion of the D
inputs and the Q outputs of HD74HC573 will follow the D inputs. When the latch enable goes low, data at
the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is
applied to the output control input, all outputs go to a high impedance state, regardless of what signals are
present at the other inputs and the state of the storage elements.
Features
• High Speed Operation: tpd (Data to Q, Q) = 11 ns typ (CL = 50 pF)
• High Output Current: Fanout of 15 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)
