Functional Description
• Low-Voltage Octal Bus Buffer (Inverted) with 5-V Tolerant Inputs and Outputs

General
The 74LCX240FT 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 74LCX240FT 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
(1) Low-voltage operation: VCC = 1.65 to 3.6 V
(2) High-speed operation: tpd = 6.5 ns (max) (VCC = 3.0 to 3.6 V)
(3) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)
(4) Power-down protection provided on all inputs and outputs
(5) Pin and function compatible with the 74 series
(74LVC/ALVC/ etc.) 240 type
