  • 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
  • Input with integrated dynamic pull-down resistors help reduce external component count
  • 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
  • Overvoltage tolerant inputs accept voltages up to 5.5 V regardless of supply voltage.
  • Ioff supports partial-power-down mode operation
  • 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
  • AEC-Q100 qualified for automotive applications

The SN74LXC1T14-Q1 is a single bit, dual-supply inverting voltage level translation device with Schmitt-trigger input. The input pin A is referenced to VCCI logic levels, and output pin Y is referenced to VCCO logic levels. The input pin A is able to accept voltages ranging from 1.1 V to 5.5 V and can be connected directly to VCCI or GND. See Device Functional Modes for a summary of the operation of the logic.

This device ensures low power consumption and is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs when the device is powered down. This inhibits current backflow into the device which prevents damage to the device.
