Octal D-type Transparent Latches (with 3-state outputs)
Octal D-type Transparent Latches (with inverted 3-state outputs)
REJ03D0666–0200 (Previous ADE-205-555)
Rev.2.00 Mar 30, 2006
Description
When the latch enable input is high, the Q outputs of HD74HCT373 will follow the D inputs and the Q outputs of HD74HCT533 will follow the inversion of 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 present at the other inputs and the state of the storage elements.
Features
LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility High Speed Operation: tpd (Data to Q) = 14 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 4.5 to 5.5 V Low Input Current: 1 µA max
Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Ordering Information
