Overview
The SN74AHC1G32HDCK3 is a single 2-input positive OR gate from the Texas Instruments AHC logic family. It operates within a supply voltage range of 2V to 5.5V and features Schmitt-trigger inputs for noise tolerance. The device provides ±8mA output drive at 5V and exhibits low power consumption with a maximum ICC of 10µA. Propagation delay reaches a maximum of 6.5ns at 5V. It is housed in a DCK (SC70-5) package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Schmitt-trigger action on all inputs ensures tolerance for slower input rise and fall times.
- Low-drive CMOS design minimizes output signal ringing, overshoot, and undershoot.
- Input voltages are tolerant up to 5.5V regardless of VCC level, facilitating down-voltage translation.
Applications
- AV Receivers
- Portable Audio Docks
- Blu-Ray Players and Home Theaters
- MP3 Players and Recorders
- Personal Digital Assistants (PDAs)
Procurement Notes
Verify the specific suffix 'HDCK3' against current manufacturer documentation, as standard listings often reference 'DCKR' or 'DCKTG4'. Confirm that the component meets the required automotive or industrial qualification standards if applicable to your system design. Ensure compatibility with existing PCB footprints for the SC70-5 package before finalizing procurement.
Selection Notes
Select this component when bus-interface applications require minimized output ringing due to slow edge rates. It is suitable for systems needing down-voltage translation where inputs accept 5.5V signals while operating at lower VCC levels. Consider its low static power consumption and high ESD protection ratings for portable and battery-powered designs.
Part Context
This part belongs to the SN74AHC1G32 series of single-function logic gates. It implements the Boolean function Y = A + B using CMOS technology. The device is designed for general-purpose digital logic applications requiring a compact footprint and robust performance across wide voltage and temperature ranges.
