DM7447AN Description

Short technical summary and product information.

The DM7447AN from Texas Instruments is a BCD to 7-segment decoder/driver IC. It is designed to drive common-anode LEDs or incandescent indicators directly. The device features active-low outputs, making it suitable for direct connection to display elements.

 

Key features include full ripple-blanking input/output controls and a lamp test input, allowing for comprehensive display management. The DM7447AN also incorporates automatic leading and trailing-edge zero-blanking control. Its open-collector outputs are capable of driving indicators directly, and the circuit provides lamp intensity modulation capability.

 

This decoder/driver is available in a 16-lead PDIP package. The DM7447AN is designed for applications requiring the conversion of Binary Coded Decimal (BCD) input to a 7-segment display output, with added features for display control and blanking.
