74HC126T14-13

Overview

The 74HC126T14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in the HC logic series. It features four independent non-inverting buffers with separate active-low enable inputs (OE). The device operates within a supply voltage range of 2.0V to 6.0V and provides output drive capabilities of 4mA at VCC = 4.5V. It utilizes TSSOP-14 surface-mount packaging and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent buffer gates with 3-state outputs controlled by separate active-low enable pins
• Incorporates Schmitt trigger action at all inputs for improved noise immunity
• Offers ESD protection exceeding JESD 22 standards across Machine, Human Body, and Charged Device 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 box systems

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the 74HC126 family includes both SO-14 and TSSOP-14 variants. Confirm RoHS compliance status and lead-free specifications against current manufacturer documentation before procurement. Ensure ordering quantities align with standard tape and reel packaging requirements specified in the datasheet.

Selection Notes

Select this component when designing systems requiring wide supply voltage operation between 2.0V and 6.0V. The inclusion of Schmitt triggers makes it suitable for noisy environments or applications with slow input signal transitions. Verify that the 4mA output drive capability meets the load requirements of the destination circuitry at the intended operating voltage.

Part Context

This component belongs to the 74HC126 family of quadruple 3-state buffers produced by Diodes Incorporated. It is part of the broader 74HC logic series designed for high-speed CMOS operations. The T14 suffix specifically denotes the TSSOP-14 surface-mount package option, distinguishing it from the SO-14 variant within the same functional family.

Replacement Considerations

Compatible substitutes include other manufacturers' 74HC126 devices in TSSOP-14 packages. Ensure replacement parts maintain identical pinout configurations, voltage ranges, and electrical characteristics such as propagation delay and output drive current.
