SN74HC32DT

Inverter Gates Overview

The SN74HC32DT is a quadruple 2-input positive-OR gate manufactured by Texas Instruments in the HC logic series. 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 significant power reduction compared to LSTTL logic ICs. It supports fanout up to 10 LSTTL loads and includes internal clamp diodes on all inputs and outputs.

Inverter Gates Feature Summary

• Contains four independent 2-input OR gates performing Boolean function Y = A + B
• Balanced CMOS push-pull outputs capable of sinking and sourcing similar currents
• Standard high-impedance CMOS inputs with internal positive and negative clamping diodes

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 against the datasheet, as the 'D' suffix indicates SOIC packaging. Confirm that the ordering suffix matches the required reel or tube quantity if applicable. Ensure the component meets RoHS compliance requirements for your assembly process. Check for any recent revisions to the datasheet that may affect thermal or electrical specifications.

Inverter Gates Selection Notes

Select this component when a quadruple 2-input OR gate is required within the HC logic family. 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 standard digital logic applications requiring low power consumption relative to LSTTL equivalents.

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, to prevent undefined operational states.

What is the maximum recommended capacitive load?

The datasheet recommends ensuring the capacitive load at the output is less than or equal to 70 pF to ensure optimal performance, though larger loads can be applied with caution.
