Product details

What this part is and where it fits

The Texas Instruments SN7414DR is a hex inverter from the 7400 series, each channel a single-input inverter with Schmitt-trigger hysteresis on the input. The Schmitt action cleans up slow or noisy edges — a ratiometric threshold at 0.6V low and 2V high means a 1V transition band that rejects chatter from switch contacts, RC oscillators, or long PCB traces. Six independent circuits in a 14-SOIC package, surface-mount, rated for 0°C to 70°C commercial environments.

Lifecycle and sourcing posture

ROHS3 compliant. For a BOM freeze or a legacy 5V TTL line, this part carries no LTB clock.

Frequently asked questions

What is the propagation delay of SN7414DR?

Maximum propagation delay is 22ns at 5V supply with a 15pF load.

Is SN7414DR equivalent to 74LS14?

Functionally equivalent — both are hex Schmitt-trigger inverters with the same pinout. The SN7414DR is the surface-mount 14-SOIC variant of the 74LS14 in the 7400 series. Electrical ratings (supply, thresholds, output drive) are the same.
