D 4.5-V to 5.5-V VCC Operation D Wide Operating Temperature Range of
- 55°C to 125°C
D Balanced Propagation Delays and
Transition Times
D Standard Outputs Drive Up To 10 LS-TTL
Loads
D Significant Power Reduction pared to
LS-TTL Logic ICs
D Inputs Are TTL-Voltage patible description/ordering information
The ’HCT573 devices are octal transparent D-type latches. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs are latched at the logic levels of the D inputs.
