74AHCU04T14-13

Overview

The 74AHCU04T14-13 is an unbuffered hex inverter manufactured by Diodes Incorporated, housed in a TSSOP-14 package. It operates within a supply voltage range of 2.0V to 5.5V and features Schmitt trigger inputs tolerant to 5.5V. The device provides six independent inverters with standard push-pull outputs, capable of sourcing or sinking 8mA at VCC = 4.5V. Propagation delay ranges from 0.5ns to 9.0ns depending on load capacitance and temperature.

Feature Summary

• Provides six independent unbuffered inverters with standard push-pull outputs
• Inputs are tolerant to 5.5V allowing operation in mixed voltage environments
• Features Schmitt trigger action at all inputs for noise immunity
• ESD protection exceeds JESD 22 standards for machine, human body, and charged device models

Applications

• Crystal oscillator circuits
• 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 TSSOP-14 packaging configuration matches design requirements. Confirm RoHS compliance and halogen-free status if environmental regulations apply. Ensure input pins are tied to VCC or ground when unused to prevent floating states. Validate operating temperature range against system thermal constraints.

Selection Notes

Select this component for designs requiring voltage translation between 3.3V and 5.5V domains due to input tolerance. Consider the unbuffered output structure for specific drive characteristics. Evaluate propagation delay specifications against signal timing requirements under expected load conditions.

Part Context

This part belongs to the 74AHCU04 series of unbuffered hex inverters. It is available in SO-14 and TSSOP-14 packages. The -13 suffix indicates tape and reel packaging with a quantity of 2500 units per reel.

Replacement Considerations

Cross-reference with other manufacturers offering 74AHCU04 equivalents in TSSOP-14 packages. Verify pinout compatibility and electrical parameter alignment before substitution.
