74AHCT86S14-13

Overview

The 74AHCT86S14-13 is a quadruple 2-input exclusive OR gate manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible inputs with Schmitt trigger action at all input pins. The device provides standard push-pull outputs capable of sourcing or sinking 8mA at VCC = 4.5V. It is available in SO-14 and TSSOP-14 packages, designed for surface mount applications.

Feature Summary

• TTL voltage level compatible inputs
• Schmitt trigger action at all inputs
• CMOS low power consumption
• ESD protection exceeding JESD 22 standards

Applications

• General purpose logic
• 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 variant required, as the S14 suffix denotes the SO-14 package while T14 indicates TSSOP-14. Confirm that the application environment strictly adheres to the 4.5V to 5.5V supply voltage limits. Ensure ESD handling protocols are followed given the CMOS construction. Check for RoHS compliance requirements if operating in regulated regions.

Selection Notes

Select this component when TTL-level interfacing is required with CMOS logic families. The inclusion of Schmitt triggers makes it suitable for noisy environments requiring clean signal transitions. Verify that the 8mA output drive capability meets the load requirements of the downstream circuitry. Consider the operating temperature range of -40°C to +125°C for industrial or automotive-grade applications.

Part Context

This part belongs to the 74AHCT series of high-speed CMOS logic devices. It implements the XOR Boolean function across four independent gates. The AHCT designation specifically ensures compatibility with TTL logic levels while maintaining CMOS performance characteristics. It serves as a fundamental building block for arithmetic logic units and data routing circuits.

Replacement Considerations

The 74AHCT86T14-13 is a confirmed substitute offering identical electrical specifications but housed in a TSSOP-14 package instead of the SO-14 package found in the S14 variant.
