74HC14T14-13

Overview

The 74HC14T14-13 is a hex inverter with Schmitt trigger inputs manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 6.0V and provides standard push-pull outputs. The device features six independent inverters, each with Schmitt trigger action at the input. It sinks or sources 4mA at VCC = 4.5V. Propagation delay ranges from 21ns to 190ns depending on voltage and temperature. Input capacitance is typically 4pF per gate.

Feature Summary

• Six independent Schmitt trigger input inverters
• Wide supply voltage operation from 2.0V to 6.0V
• Standard push-pull output configuration
• ESD protection exceeding JESD 22 standards

Applications

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

Procurement Notes

Verify the specific package type matches the design requirements, as the 74HC14 series is available in both SO-14 and TSSOP-14 packages. Confirm that the -13 suffix indicates tape and reel packaging with a quantity of 2500 units. Ensure compliance with RoHS and halogen-free specifications if required by the target application environment.

Selection Notes

Select this component when signal conditioning via hysteresis is necessary to prevent false triggering from noisy inputs. The HC logic family offers low power consumption suitable for battery-operated devices. Verify that the operating temperature range of -40°C to +125°C meets the environmental constraints of the final assembly.

Part Context

This part belongs to the 74HC14 logic family, which consists of hex inverters with Schmitt triggers. It is distinct from non-Schmitt variants like the 74HC04. The T14 suffix specifically denotes the TSSOP-14 surface-mount package, differentiating it from the S14 SO-14 variant.

Replacement Considerations

The 74HC14S14-13 serves as a direct functional substitute but utilizes an SO-14 package instead of TSSOP-14. Other manufacturers' 74HC14 equivalents may be compatible electrically but require pinout and package dimension verification.
