TC74VHC541F** is a high-speed CMOS octal bus buffer manufactured by **Toshiba**.

The TC74VHC541F is a high-speed CMOS octal bus buffer manufactured by Toshiba. Here are its key specifications, descriptions, and features:

Specifications:

  • Logic Type: Octal Buffer/Line Driver
  • Technology: CMOS (VHC)
  • Supply Voltage Range: 2.0V to 5.5V
  • High-Speed Operation: tpd = 4.0 ns (max) @ VCC = 5V
  • Low Power Consumption: ICC = 2 μA (max) @ Ta = 25°C
  • Output Drive Capability: ±8 mA @ VCC = 4.5V
  • Input Voltage Levels:
  • High-Level Input Voltage (VIH): 2.0V (min) @ VCC = 4.5V
  • Low-Level Input Voltage (VIL): 0.8V (max) @ VCC = 4.5V
  • Operating Temperature Range: -40°C to +85°C
  • Package: SOP-20 (TSSOP-20)

Descriptions:

  • The TC74VHC541F is an 8-bit non-inverting buffer/line driver with 3-state outputs.
  • It is designed for bus-oriented applications, allowing bidirectional data flow when used with appropriate control signals.
  • The device features output enable (OE) inputs for high-impedance state control, preventing bus contention.
  • It is compatible with TTL levels and operates efficiently in mixed-voltage systems.

Features:

  • Non-inverting buffer (input to output)
  • 3-state outputs for bus isolation
  • Wide operating voltage range (2.0V to 5.5V)
  • Balanced propagation delays
  • Power-down protection on inputs and outputs
  • Latch-up performance exceeds 300 mA
  • ESD protection: HBM > 2000V, MM > 200V

This device is commonly used in microprocessor systems, memory interfacing, and bus driving applications due to its high-speed operation and low power consumption.
