The 74VHCT244AFT is a dual 4-bit non-inverting buffer with 3-State outputs from Toshiba, part of the 74VHCT logic family. Operating from 4.5V to 5.5V, it provides 8mA of drive current per channel, ensuring robust signal transmission in 5V systems. Its TTL-compatible inputs allow direct interfacing with legacy TTL logic. The 20-TSSOP package is ideal for space-constrained surface-mount designs, making it a versatile choice for bus buffering and signal conditioning.

  • TTL-Compatible Inputs: Directly interfaces with 5V TTL logic without additional level-shifting circuitry.
  • High-Speed Operation: 74VHCT family provides faster propagation delays compared to standard 74HC, ideal for high-frequency signals.
  • 3-State Outputs: Enables bus sharing and multiplexing in multi-master systems.
  • Extended Temperature Range (-40°C to 125°C): Suitable for automotive and industrial applications.

5V TTL Bus Interfacing

With TTL-compatible inputs and 5V operation, it is ideal for interfacing between 5V TTL logic and CMOS devices, ensuring proper logic levels.

High-Speed Signal Buffering

The 74VHCT family offers very high-speed operation, making it suitable for buffering high-frequency clock and data signals in 5V systems.
