SN74HC32N-P2

Inverter Gates Overview

The SN74HC32N-P2 is a commercial-grade 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 clamp diode structures on all pins. It provides significant power reduction compared to LSTTL logic ICs while supporting 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 standard CMOS inputs with high impedance and balanced push-pull outputs for similar sourcing and sinking currents
• Includes positive and negative clamping diodes on all inputs and outputs to protect against voltage excursions

Inverter Gates Applications

• Monitoring error signals using fewer inputs
• Combining active-low enable signals
• Directly controlling the Enable pin of a fan driver based on multiple overheat signals

Inverter Gates Procurement Notes

Verify the specific package type and ordering suffixes against the manufacturer's current orderable addendum. Confirm that the component meets RoHS requirements and check the lead finish specifications. Ensure the selected variant aligns with the required thermal resistance and mounting style for the intended PCB layout.

Inverter Gates Selection Notes

Select this component when a wide operating voltage range between 2 V and 6 V is required. It is suitable for designs needing low power consumption relative to LSTTL alternatives. Consider the -40°C to +85°C temperature range for commercial applications. Verify input transition rates to prevent oscillations due to slow edge rates.

Inverter Gates Part Context

This device belongs to the SNx4HC32 family of quadruple 2-input OR gates. It is part of the broader HC (High-speed CMOS) logic series designed for general-purpose digital applications. The N designation typically indicates a PDIP package, though other packages like SOIC and SSOP are available within the same functional family.

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, potentially using a pull-up or pull-down resistor if the input is used intermittently.

What is the recommended bypass capacitor value?

A 0.1-μF capacitor is recommended for each VCC terminal, placed physically close to the device to prevent power disturbances.
