Overview
The Fairchild Semiconductor 74LVQ125SC is a quad buffer featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 2V to 3.6V and provides output drive currents of 12mA for both high and low states. The device contains four independent elements, each handling one bit, and is housed in a 14-SOIC surface-mount package. It functions reliably across an operating temperature range of -40°C to 85°C.
Feature Summary
- Contains four independent non-inverting buffers
- Features three-state outputs for bus driving applications
- Designed for low power and low noise operation
Applications
- Low power/low noise 3.3V systems
- Bus driver applications requiring three-state control
- General purpose buffering in CMOS digital circuits
Procurement Notes
Verify the manufacturer origin carefully, as this component was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm the specific datasheet version, as specifications may vary slightly between legacy Fairchild documentation and current onsemi releases. Ensure the part number suffix matches the required package type and environmental compliance standards for your specific design requirements.
Selection Notes
Select this component when designing systems that require buffered signals with high impedance states to prevent bus contention. It is suitable for interfaces operating at 3.3V logic levels. Consider the 14-SOIC package constraints for PCB layout. Verify compatibility with existing logic families if interfacing with other components in the circuit design.
Part Context
This component belongs to the LVQ series of low-voltage CMOS logic devices. It serves as a buffer/driver within the broader 74LVQ family. The device is functionally similar to other quad buffers but is distinguished by its specific voltage range and three-state capability. It is widely used in digital communication interfaces and memory systems.
Replacement Considerations
Potential substitutes include MC74LVX125DG, MC74LVX125DR2G, SN74LV125AD, and SN74LV125ADR. Verify pinout compatibility and electrical characteristics before substitution.
