74HCT125T14-13

Overview

The 74HCT125T14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in the TSSOP-14 package. It operates within a supply voltage range of 4.5V to 5.5V and features four independent non-inverting buffers with separate active-low enable pins (OE). The device provides high-level output current sourcing of 4mA and low-level output current sinking of 4mA at VCC = 4.5V. It includes Schmitt trigger action at all inputs for noise immunity and offers ESD protection exceeding 200-V Machine Model, 2000-V Human Body Model, and 1000-V Charged Device Model standards.

Feature Summary

• Provides four independent buffer gates with 3-state outputs controlled by separate active-low enable pins
• Features Schmitt trigger action at all inputs to ensure signal integrity
• Includes robust ESD protection meeting JESD 22 standards across multiple test models
• Designed for CMOS low power consumption while maintaining TTL voltage level compatibility

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 component matches the specific TSSOP-14 package configuration and the -13 suffix indicating tape and reel packaging. Confirm RoHS compliance and lead-free status as specified in the manufacturer documentation. Ensure the ordering quantity aligns with the standard factory pack size of 2500 units per reel to match the intended manufacturing process requirements.

Selection Notes

Select this component when a quadruple buffer with individual tri-state control is required for 5V logic applications. The HCT series ensures compatibility with TTL input levels while utilizing CMOS technology. Verify that the operating temperature range of -40°C to +125°C meets the environmental constraints of the target system design.

Part Context

This part belongs to the 74HCT125 family of quadruple 3-state buffers. It is pin-compatible with Low Power Schottky (LSTTL) logic families, facilitating direct replacement or integration into legacy designs. The device is available in both SO-14 and TSSOP-14 packages, offering flexibility for different surface mount assembly requirements.

Replacement Considerations

Compatible substitutes include the 74HCT125PW,118 from Nexperia USA Inc. and the MC74HCT125ADTR2G-Q from onsemi. These alternatives offer similar electrical characteristics and functionality for direct integration into existing designs requiring quadruple 3-state buffering.
