DM7407N

Overview

The DM7407N is a hex buffer integrated circuit manufactured by onsemi, featuring six independent gates with high-voltage open-collector outputs. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an output voltage up to 30 V. The device provides a low-level output current of 40 mA and functions within a free air operating temperature range of 0 °C to +70 °C. Propagation delay times are specified as 10 ns for low-to-high transitions and 30 ns for high-to-low transitions under standard test conditions.

Feature Summary

• Contains six independent gates performing buffer functions
• Features high-voltage open-collector outputs requiring external pull-up resistors
• Supports logic level translation between different voltage domains

Applications

• Signal buffering in digital circuits
• Logic level conversion applications
• Driving loads requiring higher voltage or current than standard TTL outputs

Procurement Notes

Verify the manufacturer origin, as the DM7407 was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm that the specific unit matches the N14A package designation for the 14-lead plastic dual-in-line form factor. Ensure compliance with any applicable RoHS directives relevant to the production batch date.

Selection Notes

Select this component when high-voltage open-collector buffering is required for driving external loads. The design necessitates the inclusion of external pull-up resistors to establish proper logical operation states. Consider the propagation delays and output current capabilities against the system timing requirements.

Part Context

This part belongs to the 7400 series of logic integrated circuits, specifically designed for general-purpose digital applications. The DM7407 variant focuses on non-inverting buffering with enhanced output drive capabilities compared to standard variants. It serves as a foundational component for interfacing low-power logic signals with higher voltage peripheral devices.

Replacement Considerations

SN5407 from Texas Instruments offers equivalent functionality with military-grade specifications.
