SN74HC32DR

Inverter Gates Overview

The SN74HC32DR is a quadruple 2-input positive-OR gate manufactured by Texas Instruments in a 14-pin SOIC package. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. The device features buffered inputs, balanced CMOS push-pull outputs, and standard 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
• Features buffered inputs and balanced CMOS push-pull outputs for similar sourcing and sinking currents
• Includes positive and negative clamping diodes on all inputs and outputs

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 ordering suffix 'DR' corresponds to the 14-pin SOIC package with tape-and-reel carrier containing 2500 units. Confirm RoHS compliance status and lead finish (NIPDAU) match project requirements. Ensure the component meets the specified commercial temperature range of -40°C to +85°C.

Inverter Gates Selection Notes

Select this component when a quadruple 2-input OR gate is required in a surface-mount SOIC package. It is suitable for designs needing wide voltage operation between 2 V and 6 V. Consider its balanced output drive capability and buffered inputs for applications requiring fast edge rates and high impedance standard CMOS inputs.

Inverter Gates Part Context

This part belongs to the SNx4HC32 family of quadruple 2-input OR gates from Texas Instruments. It is available in various packages including SSOP, PDIP, SOP, TSSOP, CDIP, CFP, and LCCC. The SN74 variant specifically denotes the commercial temperature grade (-40°C to +85°C), distinct from the SN54 military grade.

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 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.
