OCTAL TRANSPARENT

D-TYPE LATCHES WITH

3-STATE OUTPUTS

DESCRIPTION

The U74AHC573 is an octal transparent D-type latch with

3-state outputs, and it has 8 channels.

TSSOP-20

When the OE input is low and the LE input is high, the Q

outputs follow the D inputs. When OE is low and LE is low, the

Q outputs are latched at the logic levels of the D inputs.

When the OE input is high, the outputs are in the

high-impedance. The OE does not affect the internal operations

of the latches. Old data can be retained or new data can be

entered while the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power

down, OE should be tied to V_CCthrough a pull-up resistor; the

minimum value of the resistor is determined by the current-sinking

capability of the driver.

FEATURES
