74AHC1G126SE-7

Overview

The 74AHC1G126SE-7 is a single non-inverting buffer and bus driver featuring a 3-state output, manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and provides an output drive capability of ±8 mA at 5.0V. The device incorporates Schmitt trigger action at all inputs to ensure tolerance for slower input rise and fall times. It is housed in a SOT353 package and includes ESD protection exceeding 2000-V Human Body Model standards.

Feature Summary

• Single non-inverting buffer with 3-state output functionality
• Schmitt trigger inputs provide tolerance for slow signal transitions
• High ESD protection ratings across multiple testing models

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• TV, DVD, DVR, and set-top boxes
• Personal navigation systems and GPS devices

Procurement Notes

Verify the specific ordering suffix SE corresponds to the SOT353 package configuration required for your design. Confirm that the RoHS compliance status aligns with your manufacturing regulations. Ensure the tape and reel quantity matches your production line requirements. Validate that the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when a single-channel non-inverting buffer with controlled output impedance is required. The inclusion of Schmitt triggers makes it suitable for noisy environments or signals with gradual transitions. Verify that the 3-state output control via the OE pin fits your bus architecture. Consider the low power consumption characteristics for battery-operated applications.

Part Context

This part belongs to the 74AHC1G series of single-function logic ICs from Diodes Incorporated. It is designed as a compact solution for signal buffering and level shifting in modern electronic systems. The AHC logic family offers performance comparable to standard CMOS while maintaining low power dissipation. It serves as a fundamental building block for data routing and interface management.

Replacement Considerations

Check datasheets for equivalent parts from other manufacturers offering the same logical function and package type. Verify pin compatibility and electrical parameters such as propagation delay and output current capabilities. Ensure that any substitute component maintains the required ESD protection levels and operating voltage range.
