IDT74LVCH16241A
16-BIT BUFFER/DRIVER WITH
3-STATE OUTPUTS, 5 VOLT
TOLERANT I/O AND BUS-HOLD
FEATURES:
DESCRIPTION:
–
–
Typical tSK(0) (Output Skew) < 250ps
This 16-bit buffer/driver is built using advanced dual metal CMOS
ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
0.635mm pitch SSOP, 0.50mm pitch TSSOP
and 0.40mm pitch TVSOP packages
Extended commercial range of -40°C to +85°C
VCC = 3.3V ±0.3V, Normal Range
technology. Thishigh-speed, lowpowerdeviceisdesignedspecificallyto
improve both the performance and density of 3-state memory address
drivers, clock drivers, and bus-oriented receivers and transmitters.This
devicecanbeusedasfour4-bitbuffers,two8-bitbuffers,orone16-bitbuffer,
andprovidestrueoutputsandcomplementaryoutput-enable(OEandOE)
inputs.

VCC = 2.7V to 3.6V, Extended Range
CMOS power levels (0.4µW typ. static)
All inputs, outputs and I/O are 5 Volt tolerant
Supports hot insertion
All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V
devices. Thisfeatureallowstheuseofthedeviceasatranslatorinamixed
3.3V/5V supply system.
Drive Features for LVCH16241A
The LVCH16241A has “bus-hold” which retains the inputs’ last state
whenevertheinputgoestoahighimpedance. Thispreventsfloatinginputs
and eliminates the need for pull-up/down resistors.
–
–
High Output Drivers: ±24mA
Reduced system switching noise
APPLICATIONS:
The LVCH16241A has been designed with a ±24mA output driver. The
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
