DM74LS367AN

Overview

The DM74LS367AN is a hex 3-state buffer and bus driver manufactured by onsemi. It contains six independent non-inverting gates with outputs capable of driving bus lines without external resistors. The device operates within a supply voltage range of 4.75V to 5.25V. Key electrical characteristics include a high-level output current of -2.6 mA and a low-level output current of 24 mA. Propagation delay times are specified at 16 ns minimum and 25 ns maximum for both low-to-high and high-to-low transitions under a 50 pF load.

Feature Summary

• Contains six independent non-inverting buffer gates
• Outputs feature 3-state capability for bus line driving
• Disable time is shorter than enable time to prevent bus contention

Applications

• Bus-oriented systems requiring multiple drivers
• Clock drivers and buffer circuits
• Memory module address and data bus buffering

Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm package type, as variants exist in SOIC and PDIP formats. Confirm RoHS compliance status through official datasheets or environmental reports provided by the supplier. Ensure the component source matches the authorized distribution channels to avoid counterfeit parts. Check for any specific handling requirements related to static sensitivity during storage and assembly processes.

Selection Notes

Select this component when designing systems requiring multiple buffered outputs with tri-state control. The LS logic family offers standard drive capabilities suitable for general digital applications. Consider the propagation delay specifications if timing constraints are critical for the target bus architecture. Evaluate the operating temperature range to ensure compatibility with the intended environmental conditions of the final assembly.

Part Context

This part belongs to the DM74LS series of logic integrated circuits. It is functionally equivalent to other hex bus drivers within the same logic family. The device was originally developed by Fairchild Semiconductor before being acquired by onsemi. It serves as a standard solution for interfacing between different logic levels or isolating bus segments in digital circuit designs.

Replacement Considerations

Direct substitutes include SN74LS367N from Texas Instruments. Other compatible options may include devices from manufacturers producing equivalent LS-series hex buffers with 3-state outputs.
