SN74LS38DR

Inverter Gates Overview

The SN74LS38DR is a quadruple two-input positive-NAND buffer manufactured by Texas Instruments, belonging to the 74LS logic family. It features open-collector outputs and is housed in a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a commercial operating temperature range of 0°C to +70°C.

Inverter Gates Feature Summary

• Provides four independent NAND buffer channels with open-collector output configuration
• Compatible with standard TTL logic families for interface applications
• Designed for high-speed switching operations within the LS series specifications

Inverter Gates Applications

• Open-collector driving for indicator lamps and relay coils
• Bus-oriented systems requiring wired-OR logic connections
• Interface circuits between different logic families or voltage levels

Inverter Gates Procurement Notes

Verify that the ordering suffix DR corresponds specifically to the 14-SOIC surface-mount package variant. Confirm RoHS compliance status and check for alternative suffixes such as G4 or E4 if specific environmental certifications are required for your manufacturing process.

Inverter Gates Selection Notes

Select this component when open-collector outputs are necessary for wired-logic implementation or direct drive of non-TTL loads. Ensure the application voltage does not exceed the maximum ratings defined in the datasheet. Consider thermal dissipation requirements for the SOIC package under continuous load conditions.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74LS series, which utilizes Low-power Schottky technology to balance speed and power consumption. The SN74LS38 provides a specialized buffering function distinct from standard inverters, offering flexibility in digital circuit design through its open-collector architecture.

Inverter Gates Replacement Considerations

Public confirmed substitute part numbers include SN74LS38D (tube packaging) and SN74LS38N (PDIP packaging). Verify pinout compatibility and electrical characteristics before substituting.
