Additional preview pages of the HD74LVC573A datasheet.

The HD74LVC573A has eight D type latches with three state outputs in a 20 pin package.

When the latch enable input is high, the Q outputs will follow 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.

VCC = 2.0 V to 5.5 V All inputs VIH (Max. ) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VOUT (Max. ) = 5.5 V (@VCC = 0 V or output off state) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 mA (@VCC = 3.0 V to 5.5 V) Function Table Inputs OC L L L H H: L: X: Z: Q0 : LE H H L X D H L X X Output Q H L Q0 Z High level Low level Immaterial High impeda.
