SN74HC125N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125N is a quad buffer and line driver from the Texas Instruments HC logic series. It features four non-inverting channels with three-state outputs, housed in a 14-pin PDIP package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Static current is specified at 8 uA, while operating power supply current reaches 16 uA. Propagation delay varies by voltage: 150 ns at 2 V, 30 ns at 4.5 V, and 25 ns at 6 V. It supports through-hole installation and functions across temperatures from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-14 through-hole package variant. Confirm AEC-Q100 automotive qualification status if required for your application. Check RoHS compliance details on the official datasheet. Ensure the ordering part number matches the exact package and temperature grade specifications needed for production.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with three-state capability is required for through-hole designs. The HC series offers standard speed suitable for general-purpose logic. Consider the SN74HCS125QDYYRQ1 for automotive-grade Schmitt trigger inputs or surface-mount packaging alternatives like the IPWRG4 variant.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HC125 family of quad bus buffers. It shares functional similarities with other HC series logic but is distinguished by its specific through-hole PDIP packaging. The device serves as a fundamental building block for digital systems requiring signal isolation or bus driving capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the SN74HC125DR (SOIC package) or SN74HC125PW (TSSOP package). For automotive-specific requirements, consider the SN74HC125IPWRG4Q1. Verify that any substitute maintains the same 3-state output functionality and voltage range.
