74HCT14T14-13

Overview

The 74HCT14T14-13 is a hex inverter with Schmitt trigger inputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and features standard push-pull outputs. The device provides six independent inverters, each capable of sinking or sourcing 4mA at VCC = 4.5V. Propagation delay (tPD) is specified as a maximum of 20ns at VCC = 4.5V and CL = 50pF. Transition time (tt) has a maximum value of 15ns under the same conditions. The component is housed in a TSSOP-14 package and is supplied on a tape and reel.

Feature Summary

• Schmitt trigger action at all inputs for noise immunity
• CMOS low power consumption characteristics
• ESD protection exceeding JESD 22 standards
• Totally lead-free and fully RoHS compliant

Applications

• General purpose logic circuits
• PCs and networking equipment
• Notebooks and netbooks
• Computer peripherals such as hard drives
• TV, DVD, DVR, and set top boxes

Procurement Notes

Verify the specific suffix 'T14' confirms the TSSOP-14 package variant rather than the SO-14 option. Confirm the '-13' suffix indicates the 2500-unit tape and reel packaging format. Ensure the application environment strictly adheres to the 4.5V to 5.5V supply voltage limits. Validate that input transition rates do not exceed 500 ns/V to maintain switching performance specifications.

Selection Notes

Select this component when TTL voltage level compatibility is required alongside CMOS low power benefits. The wide hysteresis provided by the Schmitt triggers makes it suitable for noisy environments or slow-rising signals. Verify that the TSSOP-14 footprint aligns with the PCB layout requirements. Consider the propagation delay specifications if timing constraints are critical for the signal inversion path.

Part Context

This part belongs to the 74HCT14 family of hex inverters with Schmitt trigger inputs. It is pin-compatible with Low Power Schottky (LSTTL) logic families. The device is designed for operation with a power supply range of 4.5V to 5.5V. It serves as a digital logic gate providing Boolean inversion functions with enhanced input threshold stability.

Replacement Considerations

Direct substitutes include the 74HCT14S14-13, which shares identical electrical characteristics but utilizes an SO-14 package instead of TSSOP-14.
