CS1112 ON Semiconductor, CS1112 Datasheet - Page 5

• Manufacturer Part Number: CS1112
• Description: Quad Power Output Driver
• Manufacturer: ON Semiconductor

Typical Operation
Peripheral Interface (SPI) port using the Data Input
information in Table 1, or the outputs can be controlled via
the parallel inputs (IN0, IN1, IN2, IN3). IN0 controls OUT0,
IN1 controls OUT1, IN2 controls OUT2, and IN3 controls
