74AHC1G126W5-7

Overview

The 74AHC1G126W5-7 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 inputs to ensure tolerance for slower input rise and fall times. It is housed in a SOT25 package and complies with RoHS standards.

Feature Summary

• Features a single non-inverting buffer configuration with a 3-state output that enters a high impedance state when the output enable pin receives a LOW-level signal.
• Incorporates Schmitt trigger action at all inputs to provide circuit tolerance for slower input rise and fall times.
• Includes robust ESD protection exceeding 200-V Machine Model, 2000-V Human Body Model, and 1000-V Charged Device Model ratings.

Applications

• General purpose logic applications
• PCs, networking equipment, notebooks, netbooks, and PDAs
• Computer peripherals, hard drives, and CD/DVD ROM drives
• TV, DVD, DVR, set top boxes, personal navigation/GPS devices, MP3 players, cameras, and video recorders

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type. The W5 suffix corresponds to the SOT25 package, while other suffixes may indicate different physical form factors such as SOT353. Ensure compatibility with the intended PCB footprint before procurement.

Selection Notes

Select this component for designs requiring a single-channel non-inverting buffer with controlled output states. The inclusion of Schmitt triggers makes it suitable for noisy environments or signals with slow transitions. Verify that the required operating voltage falls within the specified 2.0V to 5.5V range.

Part Context

This part belongs to the 74AHC1G126 series of single-buffer gates with 3-state outputs produced by Diodes Incorporated. The series is designed for low-power CMOS applications and supports operation across a wide voltage spectrum. The W5 variant specifically denotes the SOT25 surface-mount package configuration.

Replacement Considerations

Cross-reference with other manufacturers offering 74AHC1G126 equivalents. Verify pinout compatibility, particularly the placement of the Output Enable (OE) pin, as variations exist between suppliers. Confirm that the replacement meets the same electrical characteristics and package dimensions.

FAQ

How does the device handle the output enable function?

The output enters a high impedance state when a LOW-level signal is applied to the output enable (OE) pin.

What is the purpose of the Schmitt trigger inputs?

The Schmitt trigger action at all inputs makes the circuit tolerant for slower input rise and fall times.
