General Description
The VHCT573A 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 main-
taining 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.
Protection circuits ensure that 0V to 7V can be applied to
the input and output
voltage. This device can be used to interface 3V to 5V
systems and two supply systems such as battery back
up. This circuit prevents device destruction due to mis-
matched supply and input voltages.
