CD74HC125QPWRG4Q1

Overview

The CD74HC125QPWRG4Q1 is a quad bus buffer manufactured by Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 2 V to 6 V and features four non-inverting channels with three-state outputs. The device utilizes HC CMOS logic technology and is housed in a TSSOP-14 surface-mount package. It meets AEC-Q100 qualification standards, ensuring reliability under harsh conditions. The component supports an operating temperature range from -40°C to +125°C, making it suitable for demanding environments.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state output control
• Qualified for automotive electronics according to AEC-Q100 standards
• Operates reliably across an extended industrial temperature range up to 125°C

Applications

• Automotive data bus buffering and line driving
• High-speed signal isolation in vehicle electronic control units
• Voltage level translation between different logic domains

Procurement Notes

Verify the specific part number against official Texas Instruments documentation to confirm the prefix 'CD' versus 'SN', as datasheets typically list 'SN74HC125'. Ensure the suffix matches the required tape and reel configuration. Confirm AEC-Q100 certification status directly through manufacturer resources before integration into automotive designs.

Selection Notes

Select this component when designing systems requiring robust signal buffering with high noise immunity in automotive contexts. The wide supply voltage range allows compatibility with various power rails. Consider the three-state capability for multiplexed bus architectures where multiple drivers share a common line without electrical contention.

Part Context

This device belongs to the SN74HC series of high-speed CMOS logic products. The 'Q1' suffix indicates automotive qualification, while 'PWR' denotes the TSSOP-14 package type. It serves as a fundamental building block for digital interface circuits, providing signal integrity and drive strength for downstream components in complex electronic assemblies.

Replacement Considerations

Check for SN74HC125QPWRG4Q1 or SN74HC125QPWREP as potential direct equivalents. Verify pinout compatibility and electrical specifications such as propagation delay and output current capabilities before substitution.
