SN74LS32NS

Inverter Gates Overview

The SN74LS32N is a Texas Instruments integrated circuit belonging to the 74LS series of low-power Schottky TTL logic devices. It contains four independent 2-input OR gates within a single 14-pin plastic dual in-line package (PDIP). The component operates with a standard supply voltage range of 4.75V to 5.25V and supports a maximum load capacitance of 15 pF. Designed for commercial applications, it functions reliably within an ambient temperature range of 0°C to 70°C.

Inverter Gates Feature Summary

• Integrates four independent 2-input OR logic gates into a single compact package
• Utilizes low-power Schottky technology to balance switching speed with reduced power consumption
• Provides robust output drive capabilities suitable for interfacing with various TTL loads

Inverter Gates Applications

• Digital signal routing and selection circuits
• Status indication logic combining multiple input signals
• Basic arithmetic operations such as binary addition carry generation

Inverter Gates Procurement Notes

Verify the specific manufacturer marking on the device body to confirm Texas Instruments origin, as this part number is widely produced by multiple vendors. Ensure the ordering suffix matches the required package style, typically N for PDIP. Confirm RoHS compliance status if environmental regulations apply to your assembly process, as legacy variants may differ from current production runs.

Inverter Gates Selection Notes

Select this component when designing systems requiring simple logical OR operations using through-hole technology. It serves as a direct replacement for older 74S32 designs where lower power dissipation is prioritized over the higher speed of the S series. Consider alternative packages like SOIC or SSOP if board space constraints require surface-mount solutions while maintaining identical electrical characteristics.

Inverter Gates Part Context

This device is part of the extensive 74xx family of logic ICs, specifically the LS variant known for its widespread adoption in general-purpose digital electronics. The 74LS32 provides a fundamental building block for combinational logic design, offering high noise immunity and standardized pinouts that facilitate easy integration into prototyping breadboards and permanent PCB layouts.

Inverter Gates Replacement Considerations

Direct functional equivalents include the SN74LS32DR (SOIC package) and SN74LS32NSR (SSOP package). Cross-vendor compatible parts from manufacturers such as ON Semiconductor or NXP are available under similar naming conventions.
