saa1042V

The SAA1042V is a stepper motor driver IC manufactured by Motorola Semiconductor Products. It is designed to drive a two-phase stepper motor in bipolar mode. The device integrates input stages, a logic section, and output stages, all housed within a 16-pin dual-in-line heat tab plastic package for enhanced heatsinking.

Key features include a drive capability of 500 mA per coil, suitable for motors operating at 6.0 V and 12 V. It incorporates built-in clamp diodes for overvoltage suppression and offers a wide logic supply voltage range. The IC accepts commands for both clockwise/counter-clockwise and half/full step operations, with inputs compatible with popular logic families like MOS, TTL, and DTL.

This component is ideal for motor control applications, particularly in legacy electronic systems, industrial automation equipment, and vintage electronic projects. Its through-hole terminals in the DIP-16 package facilitate easy integration into existing designs. The SAA1042V operates on a nominal 5V power supply, ensuring compatibility with standard logic circuits for reliable motor regulation in older equipment or projects.

The package is a 16-pin DIP with through-hole mounting. The terminal finish is Tin/Lead (Sn/Pb). While the product page indicates RoHS compliance as 'No (not RoHS certified)', the MSL is listed as '1 Unlimited' and REACH status as 'REACH Unaffected'.
