SN74AVCH1T45 - Single-Bit Dual-Supply Bus Transceiver

Description

The SN74AVCH1T45 is a single-bit noninverting bus transceiver that uses two separate configurable power-supply rails.

The A port is designed to track VCCA, which accepts any supply voltage from 1.2 V to 3.6 V.

Features

  • 1 Available in the Texas Instruments NanoStar™ and NanoFree™ Packages.
  • Control Inputs (DIR) VIH and VIL Levels Are Referenced to VCCA Voltage.
  • Bus Hold on Data Inputs Eliminates the Need for External Pullup and Pulldown Resistors.
  • VCC Isolation.
  • Fully Configurable Dual-Rail Design.
  • I/Os Are 4.6-V Tolerant.
  • Ioff Supports Partial-Power-Down Mode Operation.
  • Typical Max Data Rates.
  • 500 Mbps (1.8-V to 3.3-V Translation).
