PIN FUNCTION
Pin Function SP487
Pin 1 - DI1 - Driver 1 Input - If driver 1 output is
enabled, a logic 0 on DI1 forces driver output DO1A
low and DO1B high. A logic 1 on DI1 with driver 1
output enabled forces driver DO1A high and DO1B
low.
Pin 2 - DO1A - Driver 1 output A.
Pin 3 - DO1B - Driver 1 output B.
Pin 4 - EN1/EN2 - Driver 1 and 2 Output Enable;
Please refer to SP487 truth table (2).
Pin 5 - DO2B - Driver 2 output B.
Pin 6 - DO2A - Driver 2 output A.
Pin 7 - DI2 - Driver 2 Input - If driver 2 output is
enabled, a logic 0 on DI2 forces driver output DO2A
low and DO2B high. A logic 1 on DI2 with driver 2
output enabled forces driver DO2A high and DO2B
low.
Pin 8 - GND - Ground.
Pin 9 - DI3 - Driver 3 Input - If driver 3 output is
enabled, a logic 0 on DI1 forces driver output DO3A
low and DO3B high. A logic 1 on DI3 with driver 3
output enabled forces driver DO3A high and DO3B
low.
Pin 10 - DO3A - Driver 3 output A.
Pin 11 - DO3B - Driver 3 output B.
Pin 12 - EN3/EN4 - Driver 3 and 4 Output Enable;
Please refer to SP487 truth table (2)..
Pin 13 - DO4B - Driver 4 output B.
Pin 14 - DO4A - Driver 4 output A.
Pin 15 - DI4 - Driver 4 Input - If driver 4 output is
enabled, a logic 0 on DI4 forces driver output DO4A
low and DO4B high. A logic 1 on DI4 with driver 4
output enabled forces driver DO4A high and DO4B
low.
Pin 16 - Supply Voltage - +4.75V ⤠Vcc ⤠+5.25V.
