What the 30 ns propagation delay buys you
The Texas Instruments SN74HCT14DBR is a hex inverter with Schmitt-trigger inputs from the 74HCT series. The 30 ns maximum propagation delay at 5.5 V and 50 pF load sets the timing floor for the signal path — enough margin for 10 MHz clock distribution or debounced switch inputs without worrying about race conditions. The Schmitt-trigger inputs (0.5 V to 0.6 V low threshold, 1.9 V to 2.1 V high threshold) clean up slow edges from mechanical switches, RC oscillators, or noisy sensor outputs, giving a clean digital level straight into the next logic stage.
Supply voltage and temperature — industrial range
Quiescent current tops out at 2 µA, so it does not load the supply in low-power standby states.
Package and marking authenticity check
Housed in a 14-SSOP package (0.209" body width, 5.30 mm), surface-mount only. The supplier device package is 14-SSOP. For counterfeit screening, the laser-etched marking on the top of the package should match TI's font and date-code format for the week of manufacture. The ROHS3 compliance marking is part of the standard TI marking — any deviation in font, alignment, or missing compliance symbol flags a potential remark.
