74HCT125S14-13

Overview

The 74HCT125S14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in an SO-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 inputs (OE). The device provides TTL-compatible input levels, sinks or sources 4mA at VCC = 4.5V, and includes Schmitt trigger action at all inputs. It supports an operating temperature range from -40°C to +125°C and offers ESD protection exceeding JESD 22 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 for improved noise immunity
• Includes robust ESD protection exceeding JESD 22 standards across multiple test models
• Designed for CMOS low power consumption while maintaining TTL voltage level compatibility

Applications

• General purpose logic applications
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals, hard drives, and CD/DVD ROM drives
• TV, DVD, DVR, and set-top box systems

Procurement Notes

Verify the specific S14 suffix corresponds to the SO-14 package variant when ordering. Confirm RoHS compliance and halogen-free status requirements against project specifications. Ensure the 4.5V to 5.5V supply voltage range aligns with the target system design. Check lead time and packaging quantities as these may vary based on distributor availability.

Selection Notes

Select this component for designs requiring quad buffering with individual output control. The HCT series ensures direct compatibility with TTL logic levels without additional interface circuitry. Consider the SO-14 package dimensions for PCB layout constraints. Evaluate the 4mA drive capability against load requirements to ensure signal integrity under expected operating conditions.

Part Context

This part belongs to the 74HCT125 family of quadruple 3-state buffers produced by Diodes Incorporated. It shares functional characteristics with other variants like the TSSOP-14 version but differs in physical packaging. The S14 designation specifically identifies the small-outline package type used for surface-mount assembly.

Replacement Considerations

The 74HCT125T14-13 serves as a pin-compatible alternative utilizing the TSSOP-14 package instead of the SO-14 form factor.
