74AHC125S14-13

Overview

The 74AHC125S14-13 is a quadruple 3-state buffer manufactured by Diodes Incorporated in the AHC logic series. It features four independent non-inverting buffers with separate active-low data enable inputs (OE). The device operates within a supply voltage range of 2.0V to 5.5V and provides outputs capable of sinking or sourcing 8mA at VCC = 4.5V. Inputs are tolerant to 5.5V, facilitating mixed-voltage environments. It utilizes Schmitt trigger action at all inputs for noise immunity and includes 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 to improve noise immunity
• Inputs tolerate up to 5.5V, enabling operation in mixed voltage environments
• Offers high drive capability with outputs capable of sinking or sourcing 8mA

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 boxes

Procurement Notes

Verify the specific package type matches the design requirements, as the S14 suffix indicates an SO-14 package. Confirm RoHS compliance and lead-free status if environmental regulations apply. Ensure the operating temperature range of -40°C to +125°C aligns with the system's thermal constraints. Cross-reference the datasheet revision to confirm pinout consistency during integration.

Selection Notes

Select this component when a quad buffer with individual output control is required. The AHC series offers a balance of speed and power consumption suitable for general digital logic. The 5.5V input tolerance allows interfacing with higher voltage logic levels while powered by lower voltages. Verify that the 8mA drive current meets the load requirements of the connected circuitry.

Part Context

This part belongs to the 74AHC125 family of quadruple 3-state buffers from Diodes Incorporated. It is functionally compatible with other manufacturers' 74AHC125 devices but may differ in packaging or specific electrical characteristics. The S14 variant specifically denotes the SO-14 surface-mount package option.

Replacement Considerations

Compatible substitutes include 74AHC125T14-13 (TSSOP-14 package) and generic 74AHC125 equivalents from other vendors. Verify pinout compatibility and ensure the replacement supports the required 5.5V input tolerance and 8mA output drive current.
