Overview
The SN74AC14PW is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 2.0 V to 6.0 V and features six independent inverting circuits. The device utilizes a 14-pin TSSOP surface-mount package. Key electrical characteristics include a propagation delay of 11.0 ns, with high-level output current of -24 mA and low-level output current of 24 mA. It supports an operating temperature range from -40 °C to +85 °C.
Feature Summary
- Integrates six independent Schmitt-trigger inverters for signal conditioning
- Provides robust noise filtering through defined input hysteresis thresholds
- Supports wide supply voltage operation from 2 V to 6 V
- Delivers high drive capability with 24 mA output current
Applications
- Signal wave shaping for noisy digital inputs
- Transitioning slow-rise-time signals into clean square waves
- Oscillator circuit implementations requiring stable switching thresholds
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the component meets RoHS requirements if mandated by your design standards. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when multiple inverting channels are required in a compact surface-mount footprint. The AC logic family offers a balance of speed and power consumption suitable for general-purpose digital applications. Consider the TSSOP-14 package dimensions during PCB layout planning to ensure adequate clearance and thermal management.
Part Context
This device belongs to the SN74AC series of advanced CMOS logic products. It shares the same functional architecture as other hex inverters in the family but is distinguished by its Schmitt-trigger input configuration. The 'PW' suffix indicates the 14-lead thin-shrink small-outline package (TSSOP) variant designed for automated surface-mount assembly processes.
Replacement Considerations
SN74AC14PWR: Same logical function and pinout in tape-and-reel packaging. SN74AC14PWRE4: Lead-free version with identical electrical characteristics. SN74AC14PWG4: Green compliant version with identical electrical characteristics.
