DM7447AN

DM7447AN Description

The DM7447AN is an integrated circuit (IC) driver designed for 7-segment LED displays, offering a robust solution for driving alphanumeric displays in various electronic applications. Manufactured by onsemi, this component is part of the Power Management (PMIC) category and is housed in a Through Hole package, specifically a 16-pin DIP (Dual In-line Package). The DM7447AN operates within a temperature range of 0°C to 70°C, making it suitable for use in environments with moderate temperature variations.

This IC is designed to drive 7-segment displays using a BCD (Binary-Coded Decimal) interface, allowing for efficient and straightforward control of LED displays. The DM7447AN requires a supply voltage between 4.75V and 5.25V and draws a supply current of 60 mA, ensuring stable operation within specified power constraints. The product is classified under ECCN (Export Control Classification Number) EAR99 and HTSUS (Harmonized Tariff Schedule of the United States) code 8542.39.0001, indicating its compliance with international trade regulations.

The DM7447AN is packaged in a tube, which provides convenient handling and storage for through-hole components. It has a Moisture Sensitivity Level (MSL) of 1 (Unlimited), meaning it is not sensitive to moisture and can be stored and handled without special precautions. Despite being marked as obsolete, the DM7447AN remains a reliable choice for applications requiring a straightforward and effective 7-segment display driver.
