The SN74HCT645NE4 from Texas Instruments is an 8-bit non-inverting transceiver from the 74HCT family. It operates from 4.5V to 5.5V and provides 3-State outputs with 6mA drive. Housed in a 20-DIP package, it is designed for 5V bus interfacing in industrial, educational, and legacy systems.

  • TTL-Compatible Inputs: Easy integration with existing 5V TTL logic.
  • Through-Hole DIP Package: Ideal for prototyping and manual assembly.
  • Bidirectional Transceiver: Simplifies 5V data bus design.
  • 3-State Outputs: Allows multiple devices to share the bus.

5V Data Bus Transceiving

Ideal for bidirectional data transfer between two 5V buses in legacy industrial equipment.

Microprocessor System Interfacing

Buffers data lines between a 5V microcontroller and memory or peripherals.

Prototyping and Education
