Overview
The onsemi 74HC02DR2G is a high-performance silicon-gate CMOS integrated circuit containing four independent 2-input NOR gates. It operates within a DC supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -55°C to +125°C. The device features low input current, high noise immunity, and output drive capability equivalent to 10 LSTTL loads. Propagation delay ranges from 13 ns at 6.0 V to 75 ns at 2.0 V under standard test conditions.
Feature Summary
- Outputs directly interface with CMOS, NMOS, and TTL logic families
- Compatible with standard CMOS outputs and LSTTL outputs when pullup resistors are used
- Includes protection circuitry against damage from high static voltages or electric fields
Applications
- General-purpose digital logic processing
- Signal gating and control circuits
- Interface between different logic families
Procurement Notes
Verify the specific ordering suffix 'D' corresponds to the SOIC-14 package and 'R2G' indicates tape and reel packaging. Confirm RoHS compliance status and lead-free designation as specified in the manufacturer's ordering information section before finalizing procurement orders.
Selection Notes
Select this component for applications requiring quad 2-input NOR functionality in a compact surface-mount format. Ensure the design accommodates the specified voltage range and temperature extremes. Verify that the propagation delay characteristics meet the timing requirements of the target system architecture.
Part Context
This part belongs to the 74HC02 series of high-speed CMOS logic devices manufactured by onsemi. It serves as a direct pinout-compatible replacement for LS02 equivalents while offering improved performance metrics typical of the HC logic family. The device is designed for general-purpose digital applications requiring reliable NOR gate operations.
Replacement Considerations
The datasheet states the device is identical in pinout to the LS02. Verify compatibility with existing LS02 footprints if replacing legacy components.
