Overview
The Nexperia 74AHCT1G02GV,125 is a single 2-input NOR gate housed in a 5-lead SC-74A (SOT753) surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels, overvoltage tolerant inputs up to 5.5 V, and ESD protection exceeding 2000 V (HBM). Static characteristics include a maximum input leakage current of 2.0 μA and a maximum supply current of 40 μA at 5.5 V. Dynamic performance specifies a typical propagation delay of 4.9 ns with a 50 pF load.
Feature Summary
- Provides a single 2-input NOR logic function with balanced propagation delays and symmetrical output impedance.
- Features overvoltage tolerant inputs allowing operation as a translator in mixed voltage environments.
- Includes clamp diodes on inputs for interfacing with voltages exceeding VCC using current limiting resistors.
- Complies with JEDEC standards and offers high noise immunity with latch-up performance exceeding 100 mA.
Applications
- Mixed voltage level translation between TTL and CMOS domains
- General purpose digital logic processing
- Signal buffering and gating in industrial control systems

Selection Notes
Select this component when a single 2-input NOR gate is required with TTL-compatible input thresholds. The 74AHCT series ensures compatibility with standard TTL logic families while operating at 5 V. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range and utilizes the SC-74A package footprint for space-constrained PCB layouts.
Part Context
This part belongs to the Nexperia 74AHCT1G02 family of single 2-input NOR gates. The 'GV' designation specifically identifies the SC-74A (SOT753) plastic surface-mounted package variant. Other package options in the same logical family include TSSOP5 (GW) and XSON5 (GZ), all sharing identical electrical specifications but differing in physical dimensions and thermal characteristics.
Replacement Considerations
Direct pin-to-pin replacements within the same Nexperia portfolio include 74AHC1G02GV,125 (CMOS inputs) and 74AHCT1G02GW,125 (TSSOP package). Cross-manufacturer equivalents must be verified against the 5.5 V input tolerance and 4.5 V minimum supply requirements.
FAQ
What is the marking code for the 74AHCT1G02GV?
The marking code for the 74AHCT1G02GV is C02.
Can this device interface with signals exceeding its supply voltage?
Yes, the inputs are overvoltage tolerant up to 5.5 V, allowing them to handle signals higher than the VCC supply without damage, provided current limits are observed.
