SN74LVC1T45 - Single-Bit Dual-Supply Bus Transceiver

General Description

This single-bit noninverting bus transceiver uses two separate configurable power-supply rails.

The A port is designed to track VCCA.

VCCA accepts any supply voltage from 1.65 V to 5.5 V.

Key Features

  • ESD protection exceeds JESD 22.
  • 2000-V Human-Body Model (A114-A).
  • 200-V Machine Model (A115-A).
  • 1000-V Charged-Device Model (C101).
  • Available in the Texas Instruments NanoFree™ package.
  • Fully configurable dual-rail design allows each port to operate over the full 1.65-V to 5.5-V powersupply range.
  • VCC isolation feature.
  • if either VCC input is at GND, both ports are in the high-impedance state.
  • DIR input circuit ref.
