SN74LS32DB

Inverter Gates Overview

The SN74LS32DB is a quad 2-input positive-OR gate integrated circuit manufactured by Texas Instruments. It belongs to the 74LS series of logic components and operates within a supply voltage range of 4.75V to 5.25V. The device features four independent OR gates, each with two inputs, housed in a 14-pin SSOP surface-mount package. Key electrical characteristics include a maximum propagation delay of 22ns at 5V with a 15pF load, an output high current of 400µA, and an output low current of 8mA. Logic levels are defined with a minimum high-level input voltage of 2V and a maximum low-level input voltage of 0.8V. The component supports an operating temperature range from 0°C to 70°C.

Inverter Gates Feature Summary

• Contains four independent 2-input OR logic gates for parallel signal processing
• Utilizes Schottky TTL (LS) technology for enhanced switching speed and reduced power consumption
• Designed for surface-mount assembly using a compact 14-SSOP package format

Inverter Gates Applications

• Digital logic circuits requiring multiple OR functions
• Signal routing and selection systems
• General-purpose logic interface designs

Inverter Gates Procurement Notes

Verify the specific suffix 'DB' corresponds to the 14-SSOP package variant when sourcing. Confirm RoHS compliance status as manufacturing standards may evolve. Ensure the supplier provides official datasheets matching the Texas Instruments part number to guarantee functional equivalence. Check for alternate suffixes like 'G4' or 'E4' which may indicate environmental compliance updates without changing the core logic function.

Inverter Gates Selection Notes

Select this component when a quad OR gate configuration is required in a space-constrained surface-mount design. It is suitable for 5V logic systems utilizing standard TTL interfaces. Consider the 22ns propagation delay for timing-sensitive applications. Compare against other 74LS variants if through-hole packaging or different logic families are preferred for the specific board layout constraints.

Inverter Gates Part Context

This component is part of the extensive 74LS family of logic ICs produced by Texas Instruments. The 74LS32 base designation refers to the quad OR gate functionality, while the 'DB' suffix specifically identifies the 14-lead shrink small-outline package. This family is widely used in legacy and modern digital electronics for basic Boolean operations.

Inverter Gates Replacement Considerations

SN74LS32DR is a tape-and-reel version of the same logic function in the SOIC package. SN74LS32D offers the same quad OR gate functionality in a standard SOIC package. SN74LS32NE4 provides the equivalent logic in a 14-pin DIP package.
