Texas Instruments SN74LXC2T45/SN74LXC2T45-Q1 Dual-Supply Transceiver

Texas Instruments SN74LXC2T45/SN74LXC2T45-Q1 Dual-Supply Transceiver is a dual-bit, non-inverting bi-directional voltage level translation device. Ax pins and the control pin (DIR) are referenced to V_CCA logic levels, and Bx pins are referenced to V_CCB logic levels. The Texas Instruments SN74LXC2T45/SN74LXC2T45-Q1 A port can accept I/O voltages ranging from 1.1V to 5.5V, while the B port can accept I/O voltages from 1.1V to 5.5V. A high DIR allows data transmission from A to B, and a low DIR provides data transmission from B to A. The SN74LXC2T45-Q1 devices are AEC-Q100 qualified for automotive applications.

Features

A fully configurable dual-rail design allows each port to operate from 1.1V to 5.5V
Robust, glitch-free power supply sequencing
Up to 420Mbps support for 3.3V to 5.0V
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 32mA at 5V)
Low power consumption
- 3µA maximum (25°C)
- 6µA maximum (–40°C to 125°C)

V_CC isolation and V_CC disconnect (I_off-float) feature
- If either V_CC supply is < 100mV or disconnected, all I/O’s get pulled down and then become high-impedance
I_off supports 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 100mA per JESD 78, class II
ESD protection exceeds JESD 22
- 4000V human-body model
- 1000V charged-device model

Applications

Eliminate slow or noisy input signals
Driving indicator LEDs or Buzzers
Debouncing a mechanical switch

Infotainment head unit
ADAS fusion
