Frequently Asked Questions
What is the supply voltage range and logic family of the SN74LVC1G27DCKR?
The SN74LVC1G27DCKR belongs to the LVC (Low Voltage CMOS) logic family and operates over a wide supply voltage range of 1.65V to 5.5V. This makes it compatible with both 1.8V and 3.3V core logic systems, as well as legacy 5V designs.
What package does the SN74LVC1G27DCKR use and what are the PCB footprint dimensions?
The device uses a 6-pin SC-70 (SOT-23 variant) package with a JESD-30 code of R-PDSO-G6. The SC-70 package is one of the smallest SOT-23 footprints available, making it ideal for compact, space-constrained PCB layouts in wearables and portable devices.
Can the SN74LVC1G27DCKR inputs accept 5V signals while running at 3.3V supply?
Yes. LVC-series devices from Texas Instruments feature 5V-tolerant input pins, allowing the SN74LVC1G27DCKR to accept 5V logic-level inputs while the VCC supply is held at 3.3V or lower. This simplifies interfacing between 5V legacy peripherals and modern 3.3V microcontrollers without external level shifters.
What is a typical application for a single 3-input NOR gate like the SN74LVC1G27DCKR?
Common applications include interrupt logic (asserting an active-low signal only when all three input conditions are false), power sequencing enable circuits, bus arbitration, and general glue logic between subsystems. The single-gate format minimizes unused gates and reduces power consumption compared to quad-gate packages.
How does SN74LVC1G27DCKR pricing and availability look?
The SN74LVC1G27DCKR is priced from approximately $0.07 per unit at quantity and is widely stocked by major distributors globally. Texas Instruments maintains long-term supply commitment for this device (YTEOL 15 years), ensuring availability for production programs and after-market service.
