Octal D-Type Latch with TRI-STATEÉ Outputs
General Description
The VHC/VHCT573isan advancedhigh speed CMOSoctal
latch with TRI-STATE output fabricated with silicon gate
CMOS technology.It achievesthe high speed operation
similarto equivalent Bipolar Schottky TTL while maintaining
the CMOSlow power dissipation. This 8-bit D-type latchis
controlledbya latch enable input (LE) andan OutputEn-
able input (OE). Whenthe OEinputis high, theeightoutputs
areina high impedance state. input protection circuit ensures that 0V–7Vcanbeap-
pliedtothe input pins without regardtothe supply voltage.
This devicecanbe usedto interface5Vto3V systemsand
two supply systems suchas battery backup. This circuit
prevents device destructiondueto mismatched supplyand
input voltages.
