characteristic：

• 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)
• V_CC isolation and V_cc disconnect (I_off-float) feature
  • If either V_CC 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.
• I_off 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

explain：

The SN74LXC1T14 is a single bit, dual-supply inverting voltage level translation device with Schmitt-trigger input. The input pin A is referenced to V_CCI logic levels, and output pin Y is referenced to V_CCO 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 V_CCI 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 I_off. The I_off circuitry disables the outputs when the device is powered down. This inhibits current backflow into the device which prevents damage to the device.
