3.3V CMOS  
IDT74LVCH16244A  
16-BIT BUFFER/DRIVER  
WITH 3-STATE OUTPUTS,  
5 VOLT TOLERANT I/O AND BUS-HOLD  
FEATURES:  
DESCRIPTION:  
• Typical tSK(o) (Output Skew) < 250ps  
TheLVCH16244A16-bitbuffer/driverisbuiltusingadvanceddualmetal  
CMOStechnology. TheLVCH16244Aisdesignedspecificallytoimprove  
the performance and density of 3-state memory address drivers, clock  
drivers, and bus-oriented receivers and transmitters. The device can be  
usedasfour4-bitbuffers, two8-bitbuffers, orone16-bitbuffer. Thisdevice  
provides true outputs and symmetrical active-low output-enable (OE)  
inputs.  
• 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  
• CMOS power levels (0.4μ W typ. static)  
• All inputs, outputs, and I/O are 5V tolerant  
• Available in TSSOP package  
All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V  
devices. This feature allows the use of this device a translator in a mixed  
3.3V/5V supply system.  
The LVCH16244A has been designed with a ±24mA output driver. The  
driver is capable of driving a moderate to heavy load while maintaining  
speedperformance.  
DRIVE FEATURES:  
• High Output Drivers: ±24mA  
• Reduced system switching noise  
The LVCH16244A has “bus-hold” which retains the inputs’ last state  
whenevertheinputgoestoahighimpedance. Thispreventsfloatinginputs  
and eliminates the need for pull-up/down resistors.  
APPLICATIONS:  
• 5V and 3.3V mixed voltage systems  
• Data communication and telecommunication systems
