SN74HC125IPWRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC125IPWRQ1 is a quad bus buffer manufactured by Texas Instruments, belonging to the SN74HC125 series. It features four non-inverting buffers with three-state outputs housed in a 14-TSSOP package. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. It provides high-level and low-level output currents of 7.8 mA each. Propagation delay times are specified as 150 ns at 2 V, 30 ns at 4.5 V, and 25 ns at 6 V. The static current is 8 uA, while the operating supply current is 16 uA. It holds AEC-Q100 qualification for automotive applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IPWRQ1 confirms the industrial temperature range and automotive qualification status. Ensure the ordering part number matches the required TSSOP-14 package variant. Confirm RoHS compliance and REACH status through official manufacturer documentation before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when automotive reliability and wide voltage tolerance are required. Compare propagation delays against system timing constraints at specific supply voltages. Evaluate the trade-off between the 7.8 mA drive strength and the 16 uA operating current for power-sensitive designs.

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 devices but distinguishes itself through automotive qualification. The TSSOP-14 package offers a compact surface-mount solution suitable for space-constrained automotive PCB layouts.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74HC125D serves as a standard commercial alternative without automotive qualification. SN74HC125PWR is another commercial option in a similar package. Verify temperature ranges and qualification requirements before substituting.
