📥 Download Datasheet

General Description

The SN74AXC1T45 is a single-bit noninverting bus transceiver that uses two separate configurable power-supply rails.

The device is operational with both VCCA and VCCB supplies as low as 0.65 V.

The A port is designed to track VCCA, which accepts any supply voltage from 0.65 V to 3.6V.

Overview

SN74AXC1T45 SCES882E – DECEMBER 2017 – REVISED DECEMBER 2023 SN74AXC1T45 Single-Bit Dual-Supply Bus Transceiver With Configurable Voltage Translation.

Key Features

  • Up and down translation across 0.65 V to 3.6 V.
  • Operating temperature:.
  • 40°C to +125°C.
  • Designed with glitch suppression circuitry to improve power sequencing performance.
  • Maximum quiescent current (ICCA + ICCB) of 10µA (85°C maximum) and 16µA (125°C maximum).
  • Up to 500Mbps support when translating from 1.8 to 3.3V.
  • VCC isolation feature:.
  • If either VCC input is below 100mV, all I/Os outputs are disabled and become highimped.
