Unisonic Technologies U74AHC573

The U74AHC573 is an octal transparent D-type latch with 3-state outputs, and it has 8 channels. 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.

DESCRIPTION

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 VCC through a pull-up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
