1. Functional Description
• Low-Voltage Quad Bus Buffer with 5-V Tolerant Inputs and Outputs
2. General
The 74LCX125FT is a high-performance CMOS quad bus buffers. 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 inputs.
This device requires the 3-state control input OE to be set high to place the output into the high impedance state.
All inputs are equipped with protection circuits against static discharge.
3. Features
(1) AEC-Q100 (Rev. H) (Note 1)
(2) Wide operating temperature range: Topr = -40 to 125
(3) Low-voltage operation: VCC = 1.65 to 3.6 V
(4) High-speed operation: tpd = 7.0 ns (max) (VCC = 3.3 ± 0.3 V)
(5) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V)
(6) Power-down protection provided on all inputs and outputs
(7) Pin and function compatible with the 74 series
(74LVC/ALVC/ etc.) 125 type
Note 1: This device is compliant with the reliability requirements of AEC-Q100. For details, contact your Toshiba sales
representative.

Note: 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).
Note 1: Output in OFF state.
Note 2: High (H) or Low (L) state. IOUT absolute maximum rating must be observed.
Note 3: VOUT < GND, VOUT > VCC
Note 4: 180 mW in the range of Ta = -40 to 85 . From Ta = 85 to 125 a derating factor of -3.25 mW/shall be
applied until 50 mW.
