SN74HC14PW Texas Instruments ICs Hex Schmitt Trigger Inverter IC

SN74HC14PW is a hex Schmitt-trigger inverter IC from Texas Instruments,

designed for high-speed CMOS logic applications.

Key Features of SN74HC14PW

1. Logic Functionality

   • 6-channel inverting Schmitt trigger (hex inverter) with hysteresis input for noise immunity.

   • Boolean function: (output is the inverted input).

2. Electrical Performance

   • Wide operating voltage range: 2V to 6V, compatible with TTL and CMOS logic levels.

   • High noise immunity due to Schmitt-trigger inputs (hysteresis ~0.9V typical).

   • Low power consumption: 2µA max static current (ideal for battery-powered devices).

   • Fast propagation delay: 21ns @ 6V, 50pF load (suitable for high-speed digital circuits).

3. Output & Drive Capability

   • Balanced output drive: ±5.2mA (can drive LEDs, small relays, or other logic gates).

   • Push-pull CMOS outputs for rail-to-rail switching.

4. Robust Design

   • 14-pin TSSOP package (surface-mount, 5×4.4×1.15mm).

   • Industrial temperature range: -40°C to +85°C.

   • AEC-Q100 qualified for automotive applications.

Applications

The SN74HC14PW is widely used in:

1. Signal Conditioning

   • Converts slow/noisy analog signals (e.g., from sensors) into clean digital waveforms

2. Oscillator Circuits

   • Used in RC oscillators for clock generation in timers and microcontrollers

3. Pulse Shaping & Delay

   • Widens narrow pulses or introduces controlled delays in communication systems

4. Power Management

   • Reset circuits for microcontrollers, monitoring power supply fluctuations.

5. Interface Driving

   • Amplifies weak signals to drive LEDs, relays, or other loads

Technical Summary
