General Description
The VHC573 is an advanced high speed CMOS octal latch with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type latch is controlled by a latch enable input (LE) and an Output Enable input (OE). When the OE input is HIGH, the eight outputs are in a high impedance state.

Features
■ High Speed: tPD = 5.0 ns (typ) at VCC = 5V
■ High Noise Immunity: VNIH = VNIL = 28% VCC (Min)
■ Power Down Protection is provided on all inputs
■ Low Noise: VOLP = 0.6V (typ)
■ Low Power Dissipation: ICC = 4 µA (Max) @ TA = 25℃
■ Pin and function compatible with 74HC573
