  • 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.
