DM7407M

Overview

The DM7407M is a hex buffer integrated circuit manufactured by onsemi, housed in a 14-lead Small Outline Integrated Circuit (SOIC) package. It features six independent non-inverting gates with high-voltage open-collector outputs capable of handling up to 30V. 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. Key electrical characteristics include a maximum low-level output current of 40mA and propagation delays of 10ns (LOW-to-HIGH) and 30ns (HIGH-to-LOW) at 5V.

Feature Summary

• Contains six independent non-inverting buffer gates
• High-voltage open-collector outputs require external pull-up resistors
• Compatible with standard TTL logic levels

Applications

• TTL-to-MOS interface buffering
• Driving relays or lamps via open-collector outputs
• General-purpose signal buffering in digital circuits

Procurement Notes

Verify the specific manufacturer origin, as this part was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm RoHS compliance status for your application requirements, as older production runs may not meet current environmental standards. Ensure the SOIC-14 package matches your PCB footprint design constraints.

Selection Notes

Select this component when non-inverting buffering with high-voltage tolerance is required. The open-collector architecture allows interfacing with different voltage domains using appropriate pull-up resistors. Consider the 40mA sink capability for driving moderate loads directly without additional transistors.

Part Context

This device belongs to the standard 7400 series logic family, specifically designed for general-purpose digital applications. It serves as a fundamental building block for signal conditioning and level shifting in mixed-voltage systems where isolation between input and output voltage domains is necessary.

Replacement Considerations

Equivalent parts include SN7406NSR and SN7406DR from Texas Instruments, which offer similar functionality but are inverting buffers rather than non-inverting buffers.
