SN74LS32D

Inverter Gates Overview

The SN74LS32D is a quadruple 2-input positive-OR gate integrated circuit manufactured by Texas Instruments. It belongs to the 74LS logic series and utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.154 inches (3.90 mm). The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to 70°C. Key electrical characteristics include a maximum propagation delay of 22ns at 5V with a 15pF load, a low-level output current of 8mA, and a high-level output current of 400µA.

Inverter Gates Feature Summary

• Contains four independent 2-input OR gates for parallel signal processing
• Provides standard TTL-compatible logic levels for digital interfacing
• Supports surface-mount installation via a compact 14-SOIC footprint

Inverter Gates Applications

• Status indication circuits combining multiple input conditions

Inverter Gates Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and environmental compliance. Ensure the ordering part number matches the required SOIC variant and lead-free status. Cross-reference the manufacturer's latest datasheet for any pinout or electrical specification updates prior to final procurement decisions.

Inverter Gates Selection Notes

Select this component when a quad OR gate configuration is required in a surface-mount application. It is suitable for designs needing standard LS-TTL performance with moderate speed requirements. Consider alternative packages such as DIP or SSOP if through-hole mounting or different form factors are necessary for the specific PCB layout constraints.

Inverter Gates Part Context

This device is part of the widely used 74-series logic family, specifically the Low-power Schottky (LS) subset. It serves as a fundamental building block for combinational logic circuits. The SN74LS32D provides a cost-effective solution for implementing basic logical functions in consumer electronics, industrial controls, and general-purpose computing hardware.
