74AHC32S14-13

Overview

The 74AHC32S14-13 is a quadruple 2-input OR gate manufactured by Diodes Incorporated, housed in an SO-14 surface-mount package. It operates within a supply voltage range of 2.0V to 5.5V and features standard push-pull outputs capable of sinking or sourcing 8mA at VCC = 4.5V. The device includes Schmitt trigger action at all inputs and provides ESD protection exceeding JESD 22 standards. Propagation delay ranges from 0.5ns to 14.5ns depending on load capacitance and temperature.

Feature Summary

• Provides four independent 2-input OR gates with standard push-pull outputs for general-purpose logic applications.
• Features Schmitt trigger action at all inputs to ensure clean signal transitions in mixed-voltage environments.
• Includes robust ESD protection that exceeds JESD 22 machine model, human body model, and charged device model ratings.

Applications

• General purpose logic circuits
• 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 suffix -13 indicates tape and reel packaging containing 2500 units per reel. Confirm the S14 designation corresponds to the SO-14 package type. Ensure compatibility with RoHS 2 and halogen-free requirements if specified for the target assembly process.

Selection Notes

Select this component when a quad 2-input OR function is required in a mixed-voltage environment. The wide input tolerance allows interfacing between 3.3V and 5.5V systems. Consider the SO-14 package constraints and propagation delay specifications relative to the system clock speed and load capacitance requirements.

Part Context

This part belongs to the 74AHC32 family of high-speed CMOS logic devices. It is specifically the SO-14 packaged variant (S14) supplied in tape and reel format (-13). It serves as a digital logic solution for implementing Boolean OR functions in consumer electronics and computing hardware.

Replacement Considerations

The 74AHC32T14-13 is a direct functional substitute utilizing the TSSOP-14 package instead of SO-14. Other manufacturers may offer equivalent 74AHC32 parts, but pinout and electrical characteristics must be verified against the Diodes Incorporated datasheet.

FAQ
