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.
