SN74AVCH8T245 - 8-Bit Dual-Supply Bus Transceiver

Description

The SN74AVCH8T245 is an 8-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 Control Inputs (DIR and OE) VIH and VIL Levels Are Referenced to VCCA Voltage.
  • Bus Hold on Data Inputs Eliminates the Need for External Pullup or Pulldown Resistors.
  • VCC Isolation Feature.
  • Fully Configurable Dual-Rail Design.
  • I/Os Are 4.6-V Tolerant.
  • Ioff Supports Partial-Power-Down Mode Operation.
  • Max Data Rates:.
  • 320 Mbps (VCCA ≥ 1.8 V and VCCB ≥ 1.8 V).
  • 170 Mbps (VCCA ≤ 1.8 V or VCCB ≤ 1.8 V).
  • Latch-Up.
