SN74LXC8T245 8-bit Dual-Supply Bus Transceiver with Configurable Level Shifting

and 3-State Outputs

1 Features

3 Description

•

Fully Configurable Dual-Rail Design Allows Each

Port to Operate from 1.1 V to 5.5 V

Robust, Glitch-Free Power Supply Sequencing

Up to 420-Mbps Support for 3.3 V to 5.0 V

Schmitt-Trigger Inputs Allow for Slow or Noisy

Inputs

I/O's with Integrated Dynamic Pull-Down Resistors

Help Reduce External Component Count

Control Inputs with Integrated Static Pull-Down

Resistors Allow for Floating Control Inputs

High Drive Strength (up to 32 mA at 5 V)

Low Power Consumption

The SN74LXC8T245 is an 8-bit, dual-supply

noninverting bidirectional voltage level translation

device. Ax pins and control pins (DIR and OE) are

referenced to V _CCAlogic levels, and Bx pins are

referenced to V_CCBlogic levels. The A port is able to

accept I/O voltages ranging from 1.1 V to 5.5 V, while

the B port can accept I/O voltages from 1.1 V to 5.5 V.

A high on DIR allows data transmission from A to B

and a low on DIR allows data transmission from B to

A when OE is set to low. When OE is set to high, both

Ax and Bx pins are in the high-impedance state. See

Device Functional Modes for a summary of the

operation of the control logic.

– 4-µA Maximum (25°C)

Device Information ⁽¹⁾

– 12-µA Maximum (–40°C to 125°C)

V_CCIsolation and V_ccDisconnect (I_off-float) Feature

– If Either V_CCSupply is < 100 mV or

Disconnected, All I/O's Get Pulled-Down and

Then Become High-Impedance
