VHCT541** is a high-speed CMOS octal bus buffer manufactured by **TOSHIBA**.

The VHCT541 is a high-speed CMOS octal bus buffer manufactured by TOSHIBA. It is part of the VHCT (Very High-Speed CMOS with TTL-Compatible Inputs) series, designed for bus-oriented applications.

Key Specifications:

  • Logic Type: Octal Buffer/Line Driver (3-State)
  • Supply Voltage (VCC): 4.5V to 5.5V (5V operation)
  • High-Speed Operation: tpd = 5.5ns (Typ.) at VCC = 5V
  • TTL-Compatible Inputs: Accepts TTL-level signals (VIH = 2.0V Min., VIL = 0.8V Max.)
  • Output Drive Capability: ±8mA at VCC = 4.5V
  • 3-State Outputs: Allows bus sharing (high-impedance state when disabled)
  • Pin Configuration: 20-pin (DIP, SOP, TSSOP packages)
  • Operating Temperature Range: -40°C to +85°C

Features:

  • Low Power Consumption: ICC = 4μA (Max.) at Ta = 25°C
  • Balanced Propagation Delays: Ensures stable signal transmission
  • ESD Protection: Built-in protection against electrostatic discharge
  • Latch-Up Performance: Exceeds ±300mA per JESD78

Applications:

  • Bus buffering in microprocessors/microcontrollers
  • Memory address driving
  • Data transmission systems
  • General-purpose logic interfacing
