IDT74LVCH16245A

3.3V CMOS 16-BIT

BUS TRANSCEIVER

WITH 3-STATE OUTPUTS,

5 VOLT TOLERANT I/O AND 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. This high-speed, low power transceiver is ideal for asynchro-

nous communication between two busses (A and B). The Direction and

Output Enable controls are designed to operate this device as either two

independent 8-bit transceivers or one 16-bit transceiver. The direction

control pin (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

• Available in SSSOP and TSSOP packages

Allpinscanbedrivenfromeither3.3Vor5Vdevices. Thisfeatureallows

the use of this device as a translator in a mixed 3.3V/5V supply system.

TheLVCH16245Ahasbeendesignedwitha±24mAoutputdriver. This

driver is capable of driving a moderate to heavy load while maintaining

speedperformance.

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Reduced system switching noise

The LVCH16245A 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
