SN74LXC2T45QDCURQ1

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.

Applications

• Eliminate slow or noisy input signals
• Driving indicator LEDs or Buzzers
• Debouncing a mechanical switch
• Infotainment head unit
• ADAS fusion

Key features

• 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℃)
• 6-µA maximum (-40℃ to 125℃)
• 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℃ to +125℃
• 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
