Product data sheet
1. General description
The 74AHC573; 74AHCT573 is an 8-bit D-type transparent latch with 3-state outputs. The device
features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs
enter the latches. In this condition the latches are transparent, a latch output will change each time
its corresponding D-input changes. When LE is LOW the latches store the information that was
present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE
causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not
affect the state of the latches. Inputs are overvoltage tolerant. This feature allows the use of these
devices as translators in mixed voltage environments.
2. Features and benefits
Wide supply voltage range from 2.0 V to 5.5 V
Balanced propagation delays
All inputs have Schmitt-trigger action
Overvoltage tolerant inputs to 5.5 V
High noise immunity
CMOS low power dissipation
Common 3-state output enable input
Functionally identical to the 74AHC373; 74AHCT373
Input levels:
For 74AHC573: CMOS input level
