SN74HC7002D

Inverter Gates Overview

The SN74HC7002D is a quadruple 2-input NOR gate with Schmitt-trigger inputs in a 14-pin SOIC package. It operates from 2 V to 6 V and supports -40°C to +85°C. Propagation delay ranges from 14 ns to 33 ns depending on voltage. Output currents reach ±5.2 mA at 6 V. Input capacitance is 10 pF, and power dissipation capacitance is 20 pF per gate.

Inverter Gates Feature Summary

• Contains four independent 2-input NOR gates with Schmitt-trigger inputs for noise tolerance.
• Features balanced CMOS push-pull outputs capable of sinking and sourcing similar currents.
• Includes positive and negative clamping diodes on all inputs and outputs.

Inverter Gates Applications

• Alarm or tamper detect circuits
• S-R latch configurations

Inverter Gates Procurement Notes

Verify the specific ordering suffix against the latest TI Package Option Addendum. The 'D' suffix indicates an SOIC-14 package. Confirm current production status as some variants may be obsolete. Ensure thermal resistance values match the intended PCB layout requirements.

Inverter Gates Selection Notes

Select this component when four independent NOR functions are required within a single IC. The Schmitt-trigger inputs provide hysteresis suitable for noisy environments. Verify that the 14-pin SOIC footprint fits the design constraints and that the operating voltage range aligns with the system supply.

Inverter Gates Part Context

This device belongs to the Texas Instruments SN74HC7002 family of HCMOS logic gates. It provides standard NOR logic functionality with enhanced input characteristics compared to basic CMOS devices. The family includes various package options such as PDIP and TSSOP for different mounting needs.

Inverter Gates Replacement Considerations

Check the SN74HC7002DR for tape-and-reel packaging alternatives. Consider SN74HC7002N for through-hole DIP applications. Verify compatibility with SN74HC7002PW if space-constrained TSSOP packages are preferred.
