SN74HC32NE4

Inverter Gates Overview

The SN74HC32NE4 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

Inverter Gates Procurement Notes

Verify the specific package type matches the design requirements, as the SN74HC32 series is available in multiple configurations including SOIC, SSOP, PDIP, SO, TSSOP, CDIP, and CFP. Confirm that the ordering suffix corresponds to the desired packaging format and lead finish before finalizing procurement orders.

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 while maintaining compatibility with standard CMOS logic levels. Ensure unused inputs are terminated to either VCC or ground to prevent undefined operational states.

Inverter Gates Part Context

This part belongs to the SNx4HC32 family of quadruple 2-input OR gates produced by Texas Instruments. The HC series utilizes high-speed CMOS technology, offering performance comparable to LS-TTL with significantly lower power dissipation. The device is designed for general-purpose digital logic applications requiring reliable signal processing.

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?

It is recommended to ensure the capacitive load at the output is less than or equal to 70 pF to maintain optimal performance.
