Overview

TC74LCX540F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX540F, TC74LCX540FK Low-Voltage Octal Bus Buffer (inverted) with 5-V Tolerant Inputs and Outputs The TC74LCX540 is a high-performance CMOS octal bus buffer.

Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.

The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5 V supply environment for both inputs and outputs.

Key Features

  • Low-voltage operation: VCC = 1.65 to 3.6 V.
  • High-speed operation: tpd = 6.5 ns (max) (VCC = 3.0 to 3.6 V).
  • Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V).
  • Latch-up performance: >±500 mA.
  • Available in JEITA SOP, VSSOP (US).
  • Power-down protection provided on all inputs and outputs.
  • Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc. ) 540 type TC74LCX540F TC74LCX540FK Weight: SOP20-P-300-1.27A VSSOP20-P-.
