Overview
The SN74ACT14BQAR is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It features TTL-compatible inputs that support slow and noisy signals, making it suitable for applications requiring signal conditioning. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides continuous output drive currents of ±24 mA at 5 V and supports short-duration peak currents up to ±75 mA. The component is housed in a WQFN-14 package with wettable flanks, designed for surface-mount installation.
Feature Summary
- TTL-compatible Schmitt trigger inputs effectively handle slow-rise and noisy digital signals
- High-output drive capability supporting continuous ±24 mA and short-term ±75 mA loads
- Capable of driving 50 Ω transmission lines directly
- Constructed in a compact WQFN-14 package featuring wettable flanks for enhanced inspection
Applications
- Inverting digital signals
- Debouncing mechanical switches
- Synchronizing inverting clock inputs
Procurement Notes
Verify the specific suffix 'BQAR' against the manufacturer's official datasheet to confirm the exact package type and reel quantity. Ensure the ordering information matches the intended application requirements before procurement. Cross-reference the part number with the latest Texas Instruments documentation to validate availability and compliance status.
Selection Notes
Select this component when interfacing with TTL logic levels or processing noisy environments where hysteresis is required. The high drive current makes it appropriate for driving transmission lines or heavy capacitive loads. Verify that the operating temperature range and supply voltage constraints align with the system design specifications.
Part Context
This device belongs to the SN74ACT series of advanced CMOS logic gates. It shares functional similarities with other hex inverters but distinguishes itself through Schmitt-trigger input characteristics. The family is designed for high-speed digital applications requiring robust noise immunity and strong output drive capabilities.
Replacement Considerations
Consult the SN74ACT14 datasheet for direct pin-compatible alternatives. Verify that any substitute maintains the same Schmitt-trigger functionality and output drive specifications.
