SN74LXC8T245-Q1 Automotive 8-bit Dual-Supply Bus Transceiver with Configurable

Level Shifting and 3-State Outputs

1 Features

3 Description

•

AEC-Q100 Qualified for automotive applications

Fully configurable dual-rail design allows each port

to operate from 1.1 V to 5.5 V

The SN74LXC8T245-Q1 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.

•

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/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

•

– 4-µA maximum (25°C)

Device Information

– 25-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

I_offsupports partial-power-down mode operation

Compatible with LVC family level shifters

Control logic (DIR and OE) are referenced to V_CCA

Operating temperature from –40°C to +125°C

Latch-up performance exceeds 100 mA per JESD

78, Class II
