SN74LS14N

Inverter Gates Overview

The SN74LS14N is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It contains six independent inverters within a single 14-pin PDIP package. The device operates on a supply voltage range of 4.75 V to 5.25 V. It features distinct positive and negative threshold voltages for noise immunity. The maximum propagation delay is 22 ns at 5 V with a 15 pF load. The output drive capability includes a low-level current of 8 mA and a high-level current of -0.4 mA.

Inverter Gates Procurement Notes

Verify the manufacturer marking matches Texas Instruments specifications. Confirm the package type is standard 14-pin DIP. Check datasheet revisions for any pinout or electrical parameter updates. Ensure the component meets required operating temperature ranges for the specific application environment.

Inverter Gates Selection Notes

Select this component when input signals exhibit significant noise or slow transition times. The Schmitt trigger action prevents multiple output transitions caused by signal ringing. Compare propagation delays against system timing requirements. Verify that the TTL-compatible input levels match the driving circuit's output standards.
