Overview
The MC74LCX125DTR2G-Q is a low-voltage CMOS quad buffer with 3-state, non-inverting outputs. It operates from a 1.65 V to 5.5 V supply and features 5.0 V tolerant inputs and outputs for interface capability with 5.0 V TTL logic. The device provides balanced output sink and source capabilities of 24 mA at 3.0 V. It supports live insertion and withdrawal, guarantees high impedance when VCC = 0 V via IOFF specification, and exhibits near-zero static supply current. The component is AEC-Q100 qualified and PPAP capable.
Feature Summary
- Features 5.0 V tolerant inputs and outputs for direct interfacing with 5.0 V TTL logic systems.
- Supports live insertion and withdrawal applications while maintaining system integrity.
- Guarantees high-impedance state during power-off conditions through the IOFF specification.
- Delivers balanced 24 mA output drive capability at 3.0 V supply voltage.
Applications
- Memory address driving
- TTL level bus oriented transceiver applications
- Automotive electronic systems requiring AEC-Q100 qualification
Procurement Notes
Verify that the specific part number includes the -Q suffix to confirm AEC-Q100 qualification and PPAP capability requirements are met. Ensure the ordering information matches the required TSSOP-14 package configuration. Confirm compliance with RoHS standards and Pb-Free specifications as documented in the manufacturer's ordering guide before finalizing procurement.
Selection Notes
Select this component for designs requiring low-voltage operation down to 1.65 V combined with 5.0 V input tolerance. It is suitable for applications needing high-impedance isolation during power-down states. Consider its AEC-Q100 qualification if automotive reliability standards are mandatory. Evaluate propagation delay characteristics against system timing requirements across the specified temperature range.
Part Context
This component belongs to the MC74LCX125 series of low-voltage CMOS buffers manufactured by onsemi. It is designed for high-performance digital logic applications requiring 3-state control. The -Q suffix indicates a variant specifically qualified for automotive and other demanding environments with unique site and control change requirements.

FAQ
What is the function of the IOFF specification?
The IOFF specification guarantees that the outputs remain in a high-impedance state when the supply voltage (VCC) is equal to 0 V, preventing back-powering or unintended signal leakage.
Is the MC74LCX125DTR2G-Q suitable for automotive applications?
Yes, the -Q suffix indicates that the device is AEC-Q100 qualified and PPAP capable, meeting specific requirements for automotive and other demanding applications.
