SCES938A – OCTOBER 2021 – REVISED OCTOBER 2021

SN74LXC2T45 Dual-Bit Dual-Supply Bus Transceiver with Configurable Level Shifting

1 Features

2 Applications

•

Fully configurable dual-rail design allows each port

to operate from 1.1 V to 5.5 V

•

Eliminate slow or noisy input signals

Driving indicator LEDs or Buzzers

Debouncing a mechanical switch

Infotainment head unit

•

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

ADAS fusion

3 Description

•

The SN74LXC2T45 is

dual-bit, dual-supply

noninverting bidirectional voltage level translation

device. Ax pins and control pin (DIR) 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.

See Device Functional Modes for a summary of the

operation of the control logic.

•

– 3-µA maximum (25°C)

– 6-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) are referenced to V_CCA

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

Latch-up performance exceeds 100 mA per JESD

78, class II
