SN74LXC2T45-Q1
- AEC-Q100 qualified for automotive applications
- 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
- 3-µA maximum (25°C)
- 6-µA maximum (–40°C to 125°C)
- VCC isolation and VCC disconnect
(Ioff-float) feature
- If either VCC supply is < 100 mV or disconnected, all I/O’s get pulled-down and then become high-impedance
- Ioff supports partial-power-down mode operation
- Compatible with LVC family level shifters
- Control logic (DIR) are referenced to VCCA
- Operating temperature from –40°C to +125°C
- Latch-up performance exceeds 100 mA per JESD 78, class II
- ESD protection exceeds JESD 22
- 4000-V human-body model
- 1000-V charged-device model
The SN74LXC2T45-Q1 is a dual-bit, dual-supply noninverting bidirectional voltage level translation device. Ax pins and control pin (DIR) are referenced to VCCA logic levels, and Bx pins are referenced to VCCB logic 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.
