SN74HC7002PW

Inverter Gates Overview

The SN74HC7002PW is a quadruple 2-input NOR gate with Schmitt-trigger inputs in a 14-pin TSSOP package. It operates from 2 V to 6 V and supports -40°C to +85°C temperatures. Propagation delay ranges from 14 ns to 163 ns depending on voltage. Output currents reach ±5.2 mA at 6 V. Input leakage is ±1 µA, supply current is 2 µA, and input capacitance is 10 pF.

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 driving up to 10 LSTTL loads
• Operates across a wide voltage range of 2 V to 6 V

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 to confirm status, lead finish, and moisture sensitivity level. Confirm that the PW package designation corresponds to the 14-pin TSSOP form factor required for your PCB layout. Ensure compatibility with standard surface-mount reflow profiles.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger hysteresis is required to filter noisy signals in NOR logic applications. The HC series offers significant power reduction compared to LSTTL while maintaining compatible fanout. Verify that the operating voltage falls within the 2 V to 6 V range and that the thermal resistance of the TSSOP package suits your design constraints.

Inverter Gates Part Context

This device belongs to the Texas Instruments SN74HC7002 family of HCMOS logic gates. It provides quad 2-input NOR functionality with Schmitt triggers. The PW suffix specifically denotes the 14-lead Thin-Shrink Small-Outline Package (TSSOP), which measures 5.00 mm by 4.40 mm nominally.

Inverter Gates Replacement Considerations

SN74HC7002PWE4 and SN74HC7002PWG4 are confirmed equivalents offering identical electrical characteristics and pinouts within the same TSSOP package.
