Allegro MicroSystems Inc. Latched Sink Driver 8 Channel 500Ma Dip-18; Supply Voltage Min Allegro Microsystems A6841SA-T

The Latched Sink Driver 8 Channel 500mA DIP-18, part number A6841, is designed for applications requiring high-voltage current-sinking capabilities. It operates within a supply voltage range of 3.3V to 5V and features eight outputs, each capable of sinking up to 500mA. The device supports a maximum output voltage of 50V, making it suitable for driving inductive loads such as relays and solenoids. This driver incorporates a serial input interface with a data input rate of up to 10 MHz and is compatible with both CMOS and TTL logic levels. It includes features such as power-on reset, Schmitt trigger inputs for improved noise immunity, and internal transient protection diodes. The A6841 is available in an 18-pin DIP package and is RoHS compliant. However, it is classified as a last time buy product, indicating that it is obsolete and should not be used for new designs.
