IDT74LVCHR162245A  
BUS TRANSCEIVER  
WITH 3 STATE OUTPUTS,  
5 VOLT TOLERANT I/O, BUS-HOLD  
DESCRIPTION:  
FEATURES:  
This 16-bit bus transceiver is built using advanced dual metal CMOS  
• Typical tSK(o) (Output Skew) < 250ps  
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using  
machine model (C = 200pF, R = 0)  
technology. Thishigh-speed, lowpowerdeviceisidealforasynchronous  
communication between two buses (A and B). The Direction and Output  
Enablecontrolsaredesignedtooperatethisdeviceaseithertwoindepen-  
dent8-bittransceiversorone16-bittransceiver. Thedirectioncontrolpin  
(DIR) controls the direction of data flow. The output enable pin (OE)  
overrides the direction control and disables both ports. All inputs are  
designed with hysteresis for improved noise margin.  
• 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  
• Supports hot insertion  
Allpinscanbedrivenfromeither3.3Vor5Vdevices. Thisfeatureallows  
the use of this device as a translator in a mixed 3.3V/5V supply system.

which will significantly reduce line noise when used with light loads. The  
driver has been designed to drive ±12mA at the designated threshold  
levels.  
• Available in SSOP, TSSOP, and TVSOP packages  
DRIVE FEATURES:  
• Balanced Output Drivers: ±12mA  
• Low switching noise

and eliminates the need for pull-up/down resistors.  
APPLICATIONS:  
• 5V and 3.3V mixed voltage systems  
• Data communication and telecommunication systems
