SN74LS38DR2

Inverter Gates Overview

The SN74LS38DR2 is a quad 2-input positive-NAND gate manufactured by Motorola. It features open-collector outputs, allowing for flexible interfacing and wired-OR configurations. 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. Packaged in a 14-pin SOIC surface-mount format, it contains four independent logic circuits designed for standard TTL applications.

Inverter Gates Feature Summary

• Quad 2-input NAND logic configuration
• Open-collector output structure
• Surface-mount SOIC-14 packaging

Inverter Gates Applications

• General-purpose digital logic processing
• Wired-OR bus line implementations
• Interface circuitry requiring open-drain capabilities

Inverter Gates Procurement Notes

Verify the manufacturer origin, as Motorola's semiconductor assets were acquired by NXP. Confirm the specific LS series designation and open-collector functionality against the official datasheet. Ensure the SOIC-14 package matches design requirements. Check RoHS compliance status, as older LS series parts may not meet current environmental standards.

Inverter Gates Selection Notes

Select this component when a quad NAND gate with open-collector outputs is required for TTL-level logic. The open-collector feature necessitates external pull-up resistors for proper high-state operation. Consider power consumption and propagation delay specifications relative to system timing requirements before finalizing the design.

Inverter Gates Part Context

This part belongs to the standard 74LS (Low-power Schottky) logic family, known for balanced speed and power consumption. The 'D' suffix indicates the SOIC-14 tape-and-reel or bulk packaging variant. The 'R2' typically denotes a specific manufacturing revision or lot code within Motorola's production lines.

Inverter Gates Replacement Considerations

Direct pin-compatible replacements include other manufacturers' SN74LS38 variants. Verify that substitute parts maintain the open-collector output characteristic and compatible supply voltage ranges. Cross-reference with NXP or Texas Instruments equivalents if Motorola stock is unavailable.
