IDT74LVCH16245A  
3.3V CMOS 16-BIT  
BUS TRANSCEIVER  
WITH 3-STATE OUTPUTS,  
5 VOLT TOLERANT I/O AND BUS-HOLD  
FEATURES:  
DESCRIPTION:  
tSK(0)  
(Output Skew) < 250ps  
Typical  
This 16-bit bus transceiver is built using advanced dual metal CMOS  
technology. This high-speed,lowpowertransceiveris idealforasynchro-  
nous communication between two busses (A and B). The Direction and  
OutputEnable controls are designedtooperate this device as eithertwo  
independent 8-bit transceivers or one 16-bit transceiver. The direction  
controlpin(DIR)controls the directionofdata flow. The outputenable pin  
(OE)overrides the directioncontrolanddisables bothports.Allinputs are  
designedwithhysteresis forimprovednoise margin.  
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  
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  
Allpinscanbedrivenfromeither3.3Vor5Vdevices. Thisfeatureallows  
the use of this device as a translator in a mixed 3.3V/5V supply system.  
Drive Features for LVCH16245A:  
The LVCH16245Ahas beendesignedwitha ±24mAoutputdriver.This  
driver is capable of driving a moderate to heavy load while maintaining  
speedperformance.  
High Output Drivers: ±24 mA  
Reduced system switching noise  
APPLICATIONS:  
• 5V and 3.3V mixed voltage systems  
Data communication and telecommunication systems  
The LVCH16245A has bus-hold” which retains the inputs' last state  
whenevertheinputgoestoahighimpedance. Thispreventsfloatinginputs  
andeliminates the needforpull-up/downresistors.
