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

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

TheLVCHR162245Ahas“bus-hold”whichretainstheinputs'laststate

and eliminates the need for pull-up/down resistors.

APPLICATIONS:

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems
