General Description
The VHC164isan advanced high-speed CMOS devicefab-
ricated with silicon gate CMOS technology.It achievesthe
high-speed operation similarto equivalent Bipolar Schottky
TTLwhile maintainingthe CMOSlow power dissipation.The
VHC164isa high-speed 8-bit serial-in/parallel-out shiftreg-
ister. Serial datais entered througha 2-input AND gate syn-
chronous withthe Low-to-High transitionofthe clock.The
device featuresan asynchronous Master Reset which
clearsthe register, settingall outputs Low independentof
the clock.An input protection circuit insuresthat0Vto7V
canbe appliedto theinputpins withoutregardtothe supply
voltage. This devicecanbe usedto interface5Vto3Vsys-
temsandtwo supply systems suchas battery backup. This
circuit prevents device destructiondueto mismatched sup-
plyand input voltages.
Features Low power dissipation:
ICCe4mA (max)atTAe 25§C High noise immunity: VNIHe VNILe 28% VCC (min)All inputsare equipped witha power down protection
function Balanced propagation delays: tPLHj tPHL Low noise: VOLPe 0.8V (max)Pinand function compatible with 74HC164
