SN74HC7002DR

Inverter Gates Overview

The SN74HC7002DR is a quad 2-input NOR gate integrated circuit manufactured by Texas Instruments. It features Schmitt-trigger inputs and operates within a supply voltage range of 2 V to 6 V. The device supports an operating temperature range from -40°C to +85°C and provides buffered outputs capable of driving up to 10 LSTTL loads. It utilizes a 14-pin SOIC package with dimensions of 8.70 mm by 3.90 mm.

Inverter Gates Feature Summary

• Contains four independent 2-input NOR gates performing the Boolean function Y = A + B in positive logic.
• Schmitt-trigger input architecture provides hysteresis, ensuring tolerance to slow or noisy input signals.
• Balanced CMOS push-pull outputs allow for similar sourcing and sinking current capabilities.

Inverter Gates Applications

• Alarm and tamper detection circuits
• S-R latch configurations

Inverter Gates Procurement Notes

Verify the active production status and RoHS compliance before procurement. Confirm the specific tape and reel packaging details match system requirements. Ensure the ordering suffix aligns with the desired carrier type and quantity specifications provided in the manufacturer's documentation.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger inputs. It serves as a direct replacement for standard HC series NOR gates where buffered inputs are required. Consider the wide voltage range for compatibility with various digital logic families.

Inverter Gates Part Context

This part belongs to the SN74HC7002 family of quadruple 2-input NOR gates. It is available in multiple packages including SOIC, PDIP, and TSSOP. The DR suffix specifically denotes the SOIC package variant supplied in a tape and reel format for automated assembly processes.
