SN74HC32NSR

Inverter Gates Overview

The SN74HC32NSR is a quadruple 2-input positive-OR gate 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 standard high-impedance CMOS input characteristics. It provides significant power reduction compared to LSTTL logic ICs and supports fanout up to 10 LSTTL loads.

Inverter Gates Feature Summary

• Contains four independent 2-input OR gates performing the Boolean function Y = A + B in positive logic
• Features buffered inputs and balanced CMOS push-pull outputs for similar sourcing and sinking current capabilities
• Standard CMOS inputs are high impedance and typically modeled as a resistor in parallel with input capacitance

Inverter Gates Applications

• Monitoring error signals using fewer inputs
• Combining active-low enable signals
• Directly controlling the Enable pin of a fan driver by combining multiple overheat signals into a single active-high enable signal

Inverter Gates Procurement Notes

Verify the specific package type (SO) and suffix (SR) against the manufacturer's orderable addendum to ensure compatibility with the intended surface-mount assembly process. Confirm that the RoHS status and lead finish meet the project's environmental compliance requirements before finalizing procurement.

Inverter Gates Selection Notes

Select this component when a wide operating voltage range between 2 V and 6 V is required for digital logic applications. It is suitable for designs needing low power consumption relative to LSTTL alternatives while maintaining sufficient drive capability for standard CMOS loads. Ensure input transition rates comply with recommended conditions to prevent excessive current consumption.

Inverter Gates Part Context

This device belongs to the SNx4HC32 family of quadruple 2-input OR gates produced by Texas Instruments. It is part of the broader HC series of high-speed CMOS logic devices designed for general-purpose digital applications. The NS package variant utilizes a small-outline (SO) form factor suitable for surface-mount technology implementations.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating; they should be terminated to either VCC or ground to prevent undefined operational states.

What is the maximum capacitive load recommended for optimal performance?

The capacitive load at the output should be less than or equal to 70 pF to ensure optimal performance.
