Texas Instruments SN74LXC1T14/SN74LXC1T14-Q1 Inverting Translators

Texas Instruments SN74LXC1T14/SN74LXC1T14-Q1 Inverting Translators are single-bit voltage-level translation devices that include a Schmitt-trigger input. The input pin A of the device is referenced to VCCI logic levels, and output pin Y is referenced to VCCO logic levels. The input pin A can accept voltages ranging from 1.1V to 5.5V and can be connected directly to VCCI or GND. The Texas Instruments SN74LXC1T14/SN74LXC1T14-Q1 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 feature inhibits current backflow into the device, preventing damage to the device.

Features

  • A fully configurable dual-rail design allows each port to operate from 1.1V to 5.5V
  • Robust, glitch-free power supply sequencing
  • Up to 420Mbps support for 3.3V to 5.0V
  • Schmitt-trigger inputs allow for slow or noisy inputs
  • Input with integrated dynamic pull-down resistors helps reduce external component count
  • High drive strength (up to 32mA at 5V)
  • Low power consumption
    • 3µA maximum (25°C)
    • 6µA maximum (–40°C to 125°C)
  • VCC isolation and VCC disconnect (Ioff-float) feature
    • If either VCC supply is < 100mV or disconnected, all I/O’s get pulled down and then become high-impedance
  • Overvoltage tolerant inputs accept voltages up to 5.5V regardless of the 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
    • 4000V human-body model
    • 1000V charged-device model
  • AEC-Q100 qualified for automotive applications

Applications

  • Eliminate slow or noisy input signals
  • Driving indicator LEDs or buzzers
  • Debouncing a mechanical switch
  • General-purpose I/O (GPIO) level shifting
