Product Overview
The SN74HC14 is a Texas Instruments hex Schmitt-trigger inverter in the Signal_Chain category. It provides six independent inverters with Schmitt-trigger inputs, and the positive-logic function for each gate is Y = A inverted. The device is suited to logic inversion and input conditioning tasks where defined positive and negative switching thresholds are required.
Recommended operating conditions specify a 2 V minimum, 5 V nominal, and 6 V maximum supply range. Inputs and outputs are specified from 0 V to VCC, with SN74HC14 free-air operation from -40°C to 85°C. The related SN54HC14 rating covers -55°C to 125°C. Electrical data includes VT+, VT-, and hysteresis values across 2 V, 4.5 V, and 6 V supplies, along with VOH, VOL, leakage, ICC, input capacitance, propagation delay, transition time, and switching-test load capacitance.
Package coverage includes D SOIC-14, DB SSOP-14, N PDIP-14, NS SOP-14, PW TSSOP-14, J CDIP-14, W CFP-14, and FK LCCC-20. Absolute maximum data includes supply, clamp-current, continuous-current, junction-temperature, storage-temperature, and ESD ratings for design limit review.
