Supplier Device Package 56-SSOP

The 74FCT162543ETPVCT is a high-speed, non-inverting transceiver from the 74FCT logic family. It features 2 channels with 3-State outputs, capable of driving 24mA. Operating from 4.5V to 5.5V, it is designed for 5V systems. The BSSOP package is suitable for compact, high-density PCB designs. It is ideal for bus-oriented applications in telecom, networking, and industrial equipment.

  • High Output Drive (24mA): Can drive long bus lines and multiple loads, improving signal integrity.
  • Dual-Channel Design: Provides two independent transceivers in one package, saving board space.
  • 3-State Outputs: Enables bus sharing and prevents data contention in multi-device systems.
  • 5V Operation (4.5V-5.5V): Compatible with legacy 5V logic systems.

High-Density Server Bus Buffering

The 2-channel configuration and 24mA drive capability make it ideal for buffering address and data buses in high-density server systems, ensuring signal integrity.

Telecom Switching Equipment

In telecom switches, it can buffer control and data signals between line cards and the switching fabric, handling high-speed 5V logic.

Industrial PLC Backplane Communication
