3.3V CMOS 16-BIT
IDT74LVCH162374A
EDGE TRIGGERED D-TYPE FLIP-
FLOP WITH 3-STATE OUTPUTS,
5 VOLT TOLERANT I/O, BUS-HOLD
DESCRIPTION:
FEATURES:
The LVCH162374A16-bitedge-triggeredD-type flip-flopis builtusing
• Typical tSK(o) (Output Skew) < 250ps
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
advanced dual metal CMOS technology. This high-speed, low-power
register is ideal for use as a buffer register for data synchronization and
storage. The outputenable (OE)andclock(CLK)controls are organized
to operate each device as two 8-bit registers or one 16-bit register with
commonclock. Flow-throughorganizationofsignalpins simplifies layout.
Allinputs are designedwithhysteresis forimprovednoise margin.
All pins of the LVCH162374A can be driven from either 3.3V or 5V
devices.Thisfeatureallowstheuseofthisdeviceasatranslatorinamixed
3.3V/5Vsupplysystem.
The LVCH162374Ahas series resistors inthe device outputstructure
whichwillsignificantlyreduce line noise whenusedwithlightloads. This
driverhas beendevelopedtodrive ±12mAatthe designatedthresholds.
The LVCH162374A has “bus-hold” which retains the inputs’ last state
whenevertheinputgoestoahighimpedance.Thispreventsfloatinginputs
andeliminates the needforpull-up/downresistors.
• VCC = 3.3V ± 0.3V, Normal Range
• VCC = 2.7V to 3.6V, Extended Range
• CMOS power levels (0.4μ W typ. static)
• All inputs, outputs, and I/O are 5V tolerant
• Available in SSOP and TSSOP packages
DRIVE FEATURES:
• Balanced Output Drivers: ±12mA
• Low switching noise
APPLICATIONS:
• 5V and 3.3V mixed voltage systems
• Data communication and telecommunication systems
