74AHCT32T14-13

Overview

The 74AHCT32T14-13 is a quadruple 2-input OR gate manufactured by Diodes Incorporated, housed in a TSSOP-14 surface-mount package. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible inputs with Schmitt trigger action. The device provides standard push-pull outputs capable of sourcing or sinking 8mA at VCC = 4.5V. Propagation delay ranges from 0.5ns to 10.0ns depending on load capacitance (15pF or 50pF) and temperature conditions (-40°C to +125°C). Power dissipation capacitance per gate is typically 14.8pF.

Feature Summary

• Provides four independent 2-input OR gates with standard push-pull outputs
• Features Schmitt trigger action at all inputs for noise immunity
• Includes ESD protection exceeding JESD 22 standards across multiple test models
• Totally lead-free, fully RoHS compliant, and halogen/antimony free

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 box systems

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the 2500-unit tape and reel packaging configuration. Confirm that the TSSOP-14 package code 'T14' matches the required footprint dimensions and pad layout specifications for the target PCB design. Ensure compliance with environmental directives regarding lead-free and halogen-free requirements if applicable to the manufacturing process.

Selection Notes

Select this component when a quad 2-input OR function is required in a compact surface-mount form factor. The AHCT series ensures compatibility with TTL logic levels while maintaining CMOS low power consumption characteristics. Verify that the operating temperature range of -40°C to +125°C meets the environmental constraints of the intended application environment.
