What are the key features of 74AHCT1G02DBVR?
- Single 2-input NOR gate with AHCT high-speed CMOS technology for fast propagation delays at 5 V supply
- TTL-compatible input thresholds from 4.5 V to 5.5 V supply, enabling direct interfacing with 5 V TTL logic without pull-up resistors
- Ultra-compact 5-pin SOT-23 package minimizing PCB footprint to approximately 2.9 mm × 1.6 mm for high-density board designs
What is 74AHCT1G02DBVR used for?
The 74AHCT1G02DBVR suits glue logic applications in 5 V systems such as enable gating, interrupt generation, and signal inversion where a minimal-footprint single-gate solution reduces BOM compared to multi-gate packages. It is commonly used in industrial microcontroller boards and embedded systems for simple combinational logic functions requiring reliable 5 V operation.

Frequently Asked Questions
What supply voltage range does 74AHCT1G02DBVR require and what logic levels does it accept?
The 74AHCT1G02DBVR requires a 4.5 V to 5.5 V supply rail and accepts TTL-compatible input thresholds, with logic-high typically defined as 2 V and above. This allows it to interface directly with 5 V TTL drivers, making it a drop-in NOR gate for legacy 5 V system designs without any additional biasing components.
How does the AHCT logic family of 74AHCT1G02DBVR differ from standard HCT in terms of speed?
The AHCT (Advanced High-speed CMOS with TTL-compatible inputs) family offers faster propagation delays than standard HCT, typically under 5 ns at 5 V and 25°C, compared to HCT which may be 10 ns or more. This speed advantage suits applications running bus control logic or clock gating at frequencies above 50 MHz.
What is the physical size of the SOT-23 package for 74AHCT1G02DBVR and how does that help PCB space constraints?
The 5-pin SOT-23 package measures approximately 2.9 mm × 1.6 mm with a height of 1.0 mm. This tiny footprint allows the 74AHCT1G02DBVR to fit in areas where larger 14-pin DIP or TSSOP packages cannot, enabling compact single-gate logic placement right next to the component it controls on dense industrial or consumer electronics boards.
In which scenarios is using 74AHCT1G02DBVR as a single-gate device more practical than a quad-gate package?
Using 74AHCT1G02DBVR is more practical when only 1 NOR function is needed, since unused gates in a quad package draw quiescent current and require pull-down termination on floating inputs. A single-gate SOT-23 solution keeps the design clean, avoids unused-input handling on 3 additional gates, and reduces PCB complexity for simple 2-input gating tasks.
