74AHCT1G125QSE-7

Overview

The 74AHCT1G125QSE-7 is a single non-inverting buffer/bus driver with 3-state output, designed for automotive applications. It operates within a supply voltage range of 4.5V to 5.5V and supports ambient temperatures from -40°C to +125°C. The device provides ±8mA output drive at 4.5V and features Schmitt trigger inputs for tolerance to slower rise/fall times. It includes ESD protection exceeding 2000V (HBM) and 1000V (CDM), and latch-up resistance exceeding 100mA.

Feature Summary

• Automotive Grade 1 compliant with AEC-Q100 qualification and PPAP capability
• Schmitt trigger action on all inputs to tolerate slow signal transitions
• Outputs enter high impedance state when Output Enable (OE) pin is HIGH
• Totally lead-free, RoHS compliant, and halogen/antimony free

Applications

• Automotive applications within Grade 1 temperature range
• Industrial computing, controls, and automation systems
• High reliability networking and communications equipment
• Industrial and agricultural equipment logic circuits

Procurement Notes

Verify the specific ordering suffix 'SE' corresponds to the SOT353 package variant required for your design. Confirm that the '-7' suffix aligns with the standard tape and reel packing quantity. Ensure the component meets the necessary IATF 16949 certification requirements if your application mandates strict automotive change control protocols.

Selection Notes

Select this component when a single-channel, non-inverting buffer with controlled 3-state output is needed in a compact surface-mount footprint. It is suitable for designs requiring robust input protection against slow signals and operation across wide industrial or automotive temperature extremes without compromising power consumption levels.

Part Context

This part belongs to the 74AHCT series of logic devices, specifically engineered for CMOS low-power consumption while maintaining compatibility with TTL input levels. The '1G' designation indicates a single gate configuration, and the 'Q' signifies its qualification for automotive environments under AEC-Q100 standards.

Replacement Considerations

Check datasheets for alternative single-buffer 3-state devices in the 74AHCT family. Verify pinout compatibility, particularly the placement of the OE pin, as variations exist between manufacturers. Ensure substitute parts meet the same -40°C to +125°C operating temperature range and electrical specifications.
