SN74HC14DE4

Inverter Gates Overview

The SN74HC14DE4 is a high-speed CMOS logic device containing six independent inverters with Schmitt-trigger inputs. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -40°C to +85°C. The component provides buffered inputs, significant power reduction compared to LSTTL logic ICs, and supports fanout up to 10 LSTTL loads.

Inverter Gates Feature Summary

• Contains six independent inverters performing the Boolean function Y = A in positive logic
• Schmitt-trigger input architecture provides hysteresis for noise tolerance
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents

Inverter Gates Applications

• Synchronize inverted clock inputs
• Debounce a switch
• Invert a digital signal

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'E4' against current manufacturer documentation to confirm compliance with RoHS3 specifications and lead-free status. Confirm package dimensions match the SOIC-14 (D) form factor requirements for your PCB layout. Ensure static handling precautions are followed during assembly due to ESD sensitivity ratings.

Inverter Gates Selection Notes

Select this component when noisy or slow-rising signals require clean inversion through Schmitt-trigger hysteresis. It is suitable for designs needing balanced output drive capabilities and wide voltage operation between 2V and 6V. Verify that the required propagation delay and transition times meet system timing constraints under the specific operating voltage and load conditions.

Inverter Gates Part Context

This part belongs to the Texas Instruments SNx4HC14 family of Hex Inverters with Schmitt-Trigger Inputs. The 'SN' prefix indicates commercial grade performance, while the 'HC' designation specifies High-Speed CMOS technology. The 'D' suffix identifies the 14-pin Small Outline Integrated Circuit (SOIC) package type.
