74LVT543 Datasheet 3.3v Octal Latched Transceiver

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS 74LVT543 3.3V Octal latched transceiver with dual enable (3-State) Product specification Supersedes data of 1994 May 20 IC23 Data Handbook 1998 Feb 19 Philips Semiconductors Philips Semiconductors Product specification 3.

General Description

The 74LVT543 is a high-performance BiCMOS product designed for VCC operation at 3.3V.

This device contains two sets of D-type latches for temporary storage of data flowing in either direction.

Separate Latch Enable (LEAB, LEBA) and Output Enable (OEAB, OEBA) inputs are provided for each register to permit independent control of data transfer in either direction.

Key Features

  • Combines 74LVT245 and 74LVT373 type functions in one device.
  • 8-bit octal transceiver with D-type latch.
  • Back-to-back registers for storage.
  • Separate controls for data flow in each direction.
  • Output capability: +64mA/.
  • 32mA.
  • TTL input and output switching levels.
  • Input and output interface capability to systems at 5V supply.
  • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs.
