TC74VHC244FT(EL)** is a high-speed CMOS octal bus buffer manufactured by **Toshiba**.

The TC74VHC244FT(EL) is a high-speed CMOS octal bus buffer manufactured by Toshiba. Below are its key specifications, descriptions, and features:

Specifications:

  • Logic Type: Octal Bus Buffer/Line Driver
  • Technology: CMOS (VHC - Very High-Speed CMOS)
  • Supply Voltage Range: 2.0V to 5.5V
  • High-Speed Operation:
  • Propagation Delay (tpd): 3.8 ns (max) at 5V
  • Output Current: ±8 mA (at 5V)
  • Input Voltage Levels:
  • High-Level Input Voltage (VIH): 2.0V (min) at VCC = 5V
  • Low-Level Input Voltage (VIL): 0.8V (max) at VCC = 5V
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: TSSOP-20 (EL package)

Descriptions:

  • Function: Non-inverting 3-state buffer with two enable controls (1G and 2G).
  • Pin Configuration:
  • 1G, 2G: Active-low output enable pins (each controls 4 buffers).
  • A1-A4, A5-A8: Input pins.
  • Y1-Y4, Y5-Y8: Output pins.
  • 3-State Outputs: Allows outputs to be in high-impedance state when disabled.

Features:

  • Low Power Consumption: ICC = 4 μA (max) at Ta = 25°C
  • Balanced Propagation Delays: Ensures stable signal transmission.
  • Wide Operating Voltage: Supports 2V to 5.5V, making it compatible with TTL levels.
  • High Noise Immunity: CMOS technology provides robust noise resistance.
  • Pb-Free & RoHS Compliant: Environmentally friendly.

This part is commonly used in digital systems for signal buffering, bus driving, and interfacing between different voltage levels.
