74VHCT373A Octal D-Type Latch with 3-STATE Outputs
July 1997
Revised April 2005
74VHCT373A
Octal D-Type Latch with 3-STATE Outputs
General Description
The VHCT373A 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 operation
similar to equivalent Bipolar Schottky TTL while maintain-
ing the CMOS low power dissipation. This 8-bit D-type
latch is controlled by a latch enable input (LE) and an out-
put 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.
Protection circuits ensure that 0V to 7V can be applied to
the input and output (Note 1) pins without regard to the
supply 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.
Note 1:
Outputs in OFF-State.
