74HC125S14-13

Overview

The 74HC125S14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in an SO-14 package. It operates within a supply voltage range of 2.0V to 6.0V and features Schmitt trigger inputs for noise immunity. The device provides four independent non-inverting buffers, each with a separate active-low enable pin (OE). At VCC = 4.5V, it sinks or sources 4mA. Electrical characteristics include propagation delays ranging from 9ns to 30ns depending on voltage, and input/output leakage currents typically at ±1μA and ±5μA respectively.

Feature Summary

• Provides four independent non-inverting buffer gates with 3-state outputs controlled by separate active-low enable pins
• Incorporates Schmitt trigger action at all inputs to improve noise immunity and signal integrity
• Offers robust ESD protection exceeding JESD 22 standards across machine, human body, and charged device models
• Designed for CMOS low power consumption while maintaining wide supply voltage 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 the specific S14 suffix indicates the SO-14 surface-mount package configuration before procurement. Confirm that the -13 suffix corresponds to the standard 2500-unit tape and reel packaging format required for automated assembly processes. Ensure compliance with RoHS and halogen-free specifications if environmental regulations apply to the manufacturing environment.

Selection Notes

Select this component when designing circuits requiring isolated 3-state buffering with high noise immunity due to Schmitt trigger inputs. It is suitable for applications needing operation across a broad voltage spectrum from 2.0V to 6.0V. Consider the SO-14 package constraints regarding thermal dissipation and board space compared to TSSOP alternatives.

Part Context

This part belongs to the 74HC125 series of quadruple 3-state buffers produced by Diodes Incorporated. It shares functional similarities with other members of the family but is distinctively packaged in SO-14. The series is designed for general-purpose digital logic applications requiring reliable signal buffering and isolation in consumer electronics and computing hardware.

Replacement Considerations

The 74HC125T14-13 serves as a direct functional substitute utilizing the TSSOP-14 package instead of SO-14.
