SN74AVCH4T245-EP - 4-Bit Dual-Supply Bus Transceiver

Description

This 4-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 1.2 V to 3.6 V.

Features

  • 1.
  • Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage.
  • Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.2-V to 3.6-V Power-Supply Range.
  • I/Os Are 4.6-V Tolerant.
  • Ioff Supports Partial Power-Down-Mode Operation.
  • Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors.
  • Max Data Rates.
  • 380 Mbps (1.8-V to 3.3-V Translation).
  • 200 Mbps (.
