Octal D-Type Latch with 3-State Output
The TC74HCT373A is a high speed CMOS OCTAL LATCH
with 3-STATE OUTPUT fabricated with silicon gate C2MOS
technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
Their inputs are compatible with TTL, NMOS, and CMOS
output voltage levels.
These 8-bit D-type latches are 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.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
