General Description

The VHC373 is an advanced high speed CMOS octal

D-type latch with 3-STATE output fabricated with silicon

gate CMOS technology. It achieves the high speed oper-

ation 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). The latches appear

transparent to data when latch enable (LE) is HIGH.

When LE is LOW, the data that meets the setup time is

LATCHED. When the OE input is HIGH, the eight

outputs are in a high impedance state.

An input protection circuit ensures that 0V to 7V can be

applied to the input pins without regard to the supply

voltage. This device can be used to interface 5V to 3V

systems and two supply systems such as battery back

up. This circuit prevents device destruction due to mis-

matched supply and input voltages.
