SN74HC7002N

Inverter Gates Overview

The SN74HC7002N is a quadruple 2-input NOR gate with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device features buffered inputs, balanced CMOS push-pull outputs, and clamp diode structures on all pins. It provides significant power reduction compared to LSTTL logic ICs and supports fanout up to 10 LSTTL loads.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for tolerance to slow or noisy signals
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents
• Clamp diodes protect against input and output voltage excursions

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific package type matches the required PCB footprint, as the SN74HC7002 series includes SOIC, TSSOP, and PDIP options. Confirm RoHS compliance status and lead finish details via the manufacturer's orderable addendum. Ensure static handling precautions are observed during assembly due to ESD sensitivity ratings.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger architecture. Verify that the load capacitance remains below 70 pF for optimal performance. Ensure unused inputs are terminated to prevent undefined operational states and excessive dynamic current consumption.

Inverter Gates Part Context

This part belongs to the SN74HC7002 family of single-function logic gates. It is available in multiple packages including SOIC (D), TSSOP (PW), and PDIP (N). The N suffix specifically denotes the 14-pin plastic dual-in-line package variant.
