IDT74LVCH16540A

3.3V CMOS16-BIT

BUFFER/DRIVER WITH 3-STATE

OUTPUTS, 5 VOLT TOLERANT I/O

AND BUS-HOLD

DESCRIPTION:

This 16-bit buffer/driver is built using advanced dual metal CMOS

technology. The 3-state control gate is a 2-input AND gate with active-low

inputs so that if either output-enable (OE1 or OE2) input is high, all

correspondingoutputsareinthehigh-impedancestate.Toensurethehigh-

impedancestateduringpoweruporpowerdown,OEshouldbetiedtoVcc

through a pullup resistor; the minimum value of the resistor is determined

by the current-sinking capabiltiy of the driver.

FEATURES:

–

Typical tSK(0) (Output Skew) < 250ps

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

All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V

devices. Thisfeatureallowstheuseofthisdeviceasatranslatorinamixed

3.3V/5V supply system.

Drive Features for LVCH16540A:

The LVCH16540A has been designed with a ±24mA output driver. The

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

speedperformance.

–

High Output Drivers: ±24mA

Reduced system switching noise

APPLICATIONS:

The LVCH16540A has “bus-hold” which retains the inputs’ last state

whenevertheinputgoestoahighimpedance. Thispreventsfloatinginputs

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

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems
