SN74HC14ANSR

SN74HC14ANSR is TI’s hex Schmitt-trigger inverter in the 74HC CMOS family. It contains six independent inverters, each with a Schmitt-trigger input, providing hysteresis for clean switching of noisy or slowly varying signals.
Key points:
- Supply voltage: 2 V to 6 V; CMOS push-pull outputs; low static power.
- Six identical gates per device; fast, low-power operation.
- Schmitt-trigger inputs give good noise immunity and bounce rejection.
- Common uses: debouncing mechanical switches, signal conditioning, creating oscillators, and level shifting to CMOS logic levels.
- Packaging: 14-pin device; suffix SR indicates Tape-and-Reel packaging for automated assembly (variant packaging may differ).
Note: Always consult the exact datasheet for Vcc ranges, input thresholds, timing specs, and pinout for your chosen package.

Equivalent parts (same function: hex Schmitt-trigger inverter) from other manufacturers:
- NXP/Philips 74HC14
- Onsemi 74HC14
- Renesas 74HC14
- STMicroelectronics 74HC14
Note: 74HCT14 is not an exact equivalent (TTL input thresholds). Always verify package/pinout (DIP/SOIC, etc.).

Here are the key features of SN74HC14ANSR (Hex Schmitt-Trigger Inverter):
- 6 independent Schmitt-trigger inverters in one device.
- Schmitt-trigger inputs provide built‑in hysteresis, good for noisy or slow ramps.
- Wide supply voltage: Vcc = 2 V to 6 V (typical at 5 V).
- High-speed CMOS performance with low static power.
- CMOS-compatible outputs and standard logic drive suitable for interfacing to CMOS/TTL inputs.
- Temperature range: -40°C to +125°C (industrial/high-temp operation).
- RoHS-compliant, Pb-free packaging (NSR/SOIC 14-pin variant).
- Suitable for debouncing, waveform shaping, oscillators, and other signal-conditioning applications.
Note: Exact tpd (propagation delay) and output-drive specs vary with Vcc and load; consult the datasheet for your chosen package to get precise numbers.

- Pin count: 14 pins (14-pin package, e.g., DIP/SOIC).
- Function: Hex Schmitt-trigger inverter — six independent inverters with Schmitt-trigger inputs (hysteresis) in the 74HC series. Each inverter provides an inverted output from its input.

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational corporation that designs and manufactures semiconductors and integrated circuits, specializing in analog, mixed-signal, and digital ICs.

SN74HC14AN SR is a hex inverter with Schmitt-trigger inputs. Key applications:
- Debounce mechanical switches/relays to remove chatter.
- Condition noisy or slowly changing sensor signals (hysteresis improves noise immunity).
- RC-based oscillators and clock generators using a single Schmitt inverter.
- Pulse shaping and edge detection for timing circuits and monostable/one-shot configurations.
- Digital signal conditioning and clean drive for microcontroller or CMOS logic within 2–6 V supply.
These features leverage the input hysteresis to produce clean, TTL-to-CMOS-friendly transitions.

It’s a 14‑pin Plastic DIP (PDIP) package. The “N” suffix indicates DIP packaging.
