3.3V CMOS 16-BIT TRANS-
PARENT D-TYPE LATCH
WITH 3-STATE OUTPUTS
AND BUS-HOLD
FEATURES:
DESCRIPTION:
• 0.5 MICRON CMOS Technology
This16-bittransparentD-typelatchisbuiltusingadvanceddualmetalCMOS
technology.TheALVCH162373isparticularlysuitableforimple-mentingbuffer
registers,I/Oports,bidirectionalbusdrivers,andworkingregisters.Thisdevice
canbeusedastwo8-bitlatchesorone16-bitlatch.Whenthelatchenable(LE)
inputishigh,theQoutputsfollowthedata(D)inputs.WhenLEistakenlow,the
QoutputsarelatchedatthelevelssetupattheDinputs.
• Typical tSK(o) (Output Skew) < 250ps
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCC = 3.3V ± 0.3V, Normal Range
• VCC = 2.7V to 3.6V, Extended Range
• VCC = 2.5V ± 0.2V
• CMOS power levels (0.4μ W typ. static)
• Rail-to-Rail output swing for increased noise margin
• Available in SSOP and TSSOP packages

DRIVE FEATURES:
• Balanced Output Drivers: ±12mA
• Low switching noise
APPLICATIONS:
• 3.3V high speed systems
• 3.3V and lower voltage computing systems
