SN74LS38DB

Inverter Gates Overview

The SN74LS38DB is a quadruple 2-input positive-NAND buffer manufactured by Texas Instruments, belonging to the 74LS logic series. It features open-collector outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports TTL input levels and provides an output low current of 8 mA. Packaged in a 14-SSOP format, it functions as a standard transceiver component with a maximum propagation delay of 22 ns at 5 V and 15 pF load.

Inverter Gates Feature Summary

• Provides four independent 2-input NAND buffering channels
• Features open-collector output configuration for flexible interfacing
• Compatible with standard TTL input logic levels

Inverter Gates Applications

• General-purpose digital signal buffering
• Open-drain bus line driving applications
• Logic level translation between different voltage domains

Inverter Gates Procurement Notes

Verify the specific package marking and manufacturer date code upon receipt to ensure authenticity. Confirm that the open-collector nature of the outputs aligns with the target circuit design requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Inverter Gates Selection Notes

Select this component when a quad NAND buffer with open-collector capability is required within the LS logic family. Ensure the application can accommodate the necessary pull-up resistors associated with open-collector outputs. Verify that the 8 mA sink current rating meets the load requirements of the connected circuitry.

Inverter Gates Part Context

This part belongs to the widely used 74LS (Low-power Schottky) logic family, known for balanced speed and power consumption. It serves as a fundamental building block in digital systems requiring signal isolation or wired-OR logic configurations via its open-collector structure.

Inverter Gates Replacement Considerations

Direct pin-compatible alternatives include the SN74LS38N in DIP packages or other manufacturers' equivalents like the MC74LS38. Verify electrical characteristics match before substitution.
