Frequently Asked Questions
What is the SN74HCT14D used for?
The SN74HCT14D is a hex inverting Schmitt-trigger IC used for signal conditioning, waveform shaping, oscillator design, and switch debouncing. Its hysteresis (~0.4V) makes it ideal for converting slow or noisy digital signals into clean transitions in 2V–5.5V systems.
What package does the SN74HCT14D come in?
The SN74HCT14D is available in a 14-pin SOIC (Small Outline IC) package with 1.27mm pitch, suitable for surface-mount assembly. Texas Instruments also offers the same die in other packages such as PDIP-14 (SN74HCT14N) and SSOP-14 (SN74HCT14PW).
What is the supply voltage range for SN74HCT14D?
The SN74HCT14D operates from 2V to 5.5V, with typical use at 5V. It is HCT-family logic, meaning its input thresholds are TTL-compatible (VIL 0.8V, VIH 2.0V), making it ideal for interfacing 5V TTL outputs with CMOS logic systems.
What are alternatives to the SN74HCT14D?
Drop-in alternatives include the 74HCT14 from NXP (74HCT14D), ON Semiconductor (MC74HCT14ADR2G), and STMicroelectronics (M74HCT14RM13TR). For 3.3V-only designs, consider the SN74LVC14A (1.65V–5.5V, lower voltage logic).
What is the propagation delay of SN74HCT14D?
The SN74HCT14D has a typical propagation delay of 4.5ns (tpd) at VCC = 5V and 25°C. Maximum propagation delay is 18ns over temperature and supply extremes. This makes it suitable for high-speed digital logic applications up to tens of MHz.
