With the clock-enable (CLKEN) input low, the nine D-type edge-
triggeredflip-flops enterdata onthe low-to-hightransitions ofthe clock.
TakingCLKEN highdisables theclockbuffer,latchingtheoutputs. This
devicehas noninvertingdata(D)inputs.Takingtheclear(CLR)inputlow
causes the nine Qoutputs togolow, independentlyofthe clock.

Drive Features for LVC823A:
–
–
High Output Drivers: ±24mA
Reduced system switching noise
APPLICATIONS:
The LVC823A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speedperformance.
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
Toensure the high-impedance state duringpoweruporpowerdown,
OE shouldbe tiedtoVCC througha pullupresistor;the minimumvalue of
the resistoris determinedbythe current-sinkingcapabilityofthe driver.
Inputs canbedrivenfromeither3.3Vor5Vdevices.This featureallows
the use ofthis device as a translatorina mixed3.3V/5Vsystemenviron-
ment.
