DM93L38N

Overview

The DM93L38N is a high-speed Schottky TTL quad 2-input NAND gate manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 4.5 V to 5.5 V and supports input voltages up to 5.5 V. The device features a propagation delay of 6 ns at a 50 pF load and offers a noise margin of 0.4 V. It is designed for standard logic applications requiring fast switching speeds and low power consumption, housed in a 14-pin plastic DIP package.

Feature Summary

• High-speed Schottky TTL technology for rapid signal processing
• Quad configuration providing four independent 2-input NAND gates
• Low power dissipation characteristics suitable for dense logic designs

Applications

• General-purpose digital logic circuits
• Data acquisition systems
• Industrial control logic interfaces

Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successor entities, noting that original production may be discontinued. Confirm the package type matches the required 14-pin DIP form factor. Ensure the device meets the specific voltage and speed requirements for your application, as availability from authorized distributors may vary due to age.

Selection Notes

Select this component when a fast, low-power NAND gate is required in a through-hole DIP package. Compare against modern CMOS equivalents if lower voltage operation is needed, as this device is optimized for 5V logic levels. Consider pin compatibility with existing PCB footprints if replacing older designs.

Part Context

This part belongs to the 93L series of Schottky TTL logic devices, known for balancing speed and power efficiency. It serves as a fundamental building block in digital electronics, often used in microprocessor interface circuits and memory addressing logic where reliable high-speed switching is critical.

Replacement Considerations

Direct replacements include the DM93S38N or equivalent 74LS00 variants, though electrical characteristics such as speed and power may differ. Verify pinout compatibility before substitution.
