74AHCT1G125SE-7

Overview

The 74AHCT1G125SE-7 is a single non-inverting buffer with 3-state output from Diodes Incorporated, housed in an SOT353 package. It operates within a supply voltage range of 4.5V to 5.5V and provides ±8mA output drive at 5.0V. The device features Schmitt trigger inputs for tolerance to slow rise/fall times and includes ESD protection exceeding 200V machine model, 2000V human body model, and 1000V charged device model standards.

Feature Summary

• Single non-inverting buffer gate with 3-state output functionality
• Schmitt trigger action on all inputs for improved noise immunity
• Robust ESD protection meeting JESD 22 standards
• Low power CMOS consumption with latch-up performance exceeding 100mA

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• TVs, DVD players, DVRs, and set-top boxes
• Phones, personal navigation/GPS devices, MP3 players, cameras, and video recorders

Procurement Notes

Verify the specific ordering suffix 'SE' corresponds to the SOT353 package configuration required for your design. Confirm that the -7 suffix indicates tape and reel packaging quantities of 3000 units per reel. Ensure compatibility with RoHS compliance requirements and check for any applicable exemptions before finalizing procurement specifications.

Selection Notes

Select this component when a compact single-channel buffer with high impedance state control is needed. The AHCT series ensures TTL-compatible input thresholds while maintaining CMOS low power characteristics. Consider the SOT353 package dimensions for space-constrained PCB layouts and verify thermal resistance values if operating near maximum temperature limits.

Part Context

This part belongs to the 74AHCT logic family, designed for high-speed CMOS applications with TTL-compatible inputs. It serves as a bus driver or buffer within general-purpose digital logic systems. The product line emphasizes low power consumption and robust environmental protection features suitable for consumer electronics and computing peripherals.

Replacement Considerations

Direct substitutes include the 74AHCT1G125W5-7 (SOT25 package) from Diodes Incorporated. Other manufacturers offer equivalent parts such as Nexperia's 74AHCT1G125GW,125 and Texas Instruments' SN74AHCT1G125DBVR. Verify pinout compatibility and package dimensions before substitution.

FAQ

How does the Output Enable (OE) pin control the 3-state output?

When the OE pin is applied with a HIGH-level signal, the output enters a high impedance state. When OE is LOW, data passes from the A input to the Y output.

What are the ESD protection ratings for this device?

The device exceeds 200-V Machine Model (A115-A), 2000-V Human Body Model (A114-A), and 1000-V Charged Device Model (C101C) per JESD 22 standards.
