SN74LVC2T45-EP - DUAL-BIT DUAL-SUPPLY BUS TRANSCEIVER

Description

This dual-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.

Features

  • 1.
  • 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 Power-Supply Range.
  • VCC Isolation Feature.
  • If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State.
  • DIR Input Circuit Referenced to VCCA.
  • Low Power Consumption, 10-mA Max ICC.
  • ±24-mA Output Drive at 3.3 V.
  • Ioff Supports Partial-Power-Down Mode Operation.
