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.
ROHS3 compliant.
Maximum propagation delay is 22ns at 5V supply with a 15pF load.
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.
