SN74HC7002PWG4

Inverter Gates Overview

The SN74HC7002PWG4 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 for input and output protection. 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
• Wide operating voltage range from 2 V to 6 V
• Clamp diode structures protect against over-voltage conditions

Inverter Gates Applications

• Alarm / tamper detect circuit
• S-R latch

Inverter Gates Procurement Notes

Verify the specific package type (TSSOP-14) and ordering suffix (G4 indicating RoHS compliance) match your design requirements. Confirm that the active production status aligns with long-term availability needs. Ensure ESD handling precautions are followed during installation due to the sensitivity of CMOS inputs.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger architecture. It is suitable for designs requiring low power consumption relative to LSTTL alternatives. Verify that the 2 V to 6 V supply range accommodates your system's voltage levels. Consider the TSSOP-14 package dimensions for PCB layout constraints.
