TC74LCX16240FT
Low-Voltage 16-Bit Bus Buffer (inverted) with 5-V Tolerant Inputs and Outputs
The TC74LCX16240FT is a high-performance CMOS 16-bit bus
buffer. Designed for use in 2.5-V or 3.3-V systems, it achieves
high-speed operation while maintaining the CMOS low power
dissipation.
The device is designed for low-voltage (2.5-V or 3.3-V ) V
CC
applications, but it could be used to interface to 5-V supply
environment for both inputs and outputs.
This device is inverting 3-state buffer having four active-low
output enables. It can be used as four 4-bit buffers two 8-bit
buffers or one 16-bit buffer. When the OE input is high, the
outputs are in a high-impedance state. This device is designed to
be used with 3-state memory address drivers, etc.
Weight: 0.25 g (typ.)
All inputs are equipped with protection circuits against static discharge.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
