  • 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

The SN74LXC2T45 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.
