74LVC4245AD - Octal dual supply translating transceiver

Download the 74LVC4245AD datasheet PDF. This datasheet also covers the 74LVC4245A variant, as both devices belong to the same octal dual supply translating transceiver family and are provided as variant models within a single manufacturer datasheet.

Description

The 74LVC4245A is an octal dual supply translating transceiver featuring 3-state bus compatible outputs in both send and receive directions.

It is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment.

Features

  • 5 V tolerant inputs/outputs, for interfacing with 5 V logic.
  • Wide supply voltage range:.
  • 3 V bus (VCC(B)): 1.5 V to 3.6 V.
  • 5 V bus (VCC(A)): 1.5 V to 5.5 V.
  • CMOS low-power consumption.
  • TTL interface capability at 3.3 V.
  • Overvoltage tolerant control inputs to 5.5 V.
  • High-impedance when VCC(A) = 0 V.
  • Complies with JEDEC standard no. JESD8B/JESD36.
  • Latch-up performance meets requirements of JESD78 Class 1.

74LVC4245A Octal dual supply translating transceiver; 3-state Rev. 15 — 29 November 2024 Product data sheet 1. General description The 74LVC4245A is an octal dual supply translating transceiver featuring 3-state bus compatible outputs in both send and receive directions. It is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment. The device features an output enable input (OE) and a send/receive input (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state, effectively isolating the buses. In suspend mode, when either supply is zero, there is no current path between supplies. VCCA ≥ VCCB, except in suspend mode.
