Low-Voltage Octal Bus Buffer (inverted) with 5-V Tolerant Inputs and Outputs
The TC74LCX240 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.
The 74LCX240 is an inverting 3-state buffer having two active-low output enables. This device is designed to be used with 3-state memory address drivers, etc.
All inputs are equipped with protection circuits against static discharge.
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) Ouput 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.) 240 type
