PIN FUNCTION
SP487
Pin Function SP487
Pin - DI
- Driver Input - If driver output is
enabled, a logic 0 on DI
forces driver output DOA
low and DO
B high. A logic on DI with driver
output enabled forces driver DO
A high and DOB
low.
Pin 2 - DO
A - Driver output A.
Pin 3 - DO
B - Driver output B.
Pin 4 - EN
/EN2 - Driver and 2 Output Enable;
Please refer to SP487 truth table (2).
Pin 5 - DO
2B - Driver 2 output B.
Pin 6 - DO
2A - Driver 2 output A.
Pin 7 - DI
2 - Driver 2 Input - If driver 2 output is
enabled, a logic 0 on DI
2 forces driver output DO2A
low and DO
2B high. A logic on DI2 with driver 2
output enabled forces driver DO
2A high and DO2B
low.
Pin 8 - GND - Ground.
Pin 9 - DI
3 - Driver 3 Input - If driver 3 output is
enabled, a logic 0 on DI
forces driver output DO3A
low and DO
3B high. A logic on DI3 with driver 3
output enabled forces driver DO
3A high and DO3B
low.
Pin 0 - DO
3A - Driver 3 output A.
Pin - DO
3B - Driver 3 output B.
Pin 2 - EN
3/EN4 - Driver 3 and 4 Output Enable;
Please refer to SP487 truth table (2)..
Pin 3 - DO
4B - Driver 4 output B.
Pin 4 - DO
4A - Driver 4 output A.
Pin 5 - DI
4 - Driver 4 Input - If driver 4 output is
enabled, a logic 0 on DI
4 forces driver output DO4A
low and DO
4B high. A logic on DI4 with driver 4
output enabled forces driver DO
4A high and DO4B
low.
Pin 16 - Supply Voltage - +4.75V ≤ Vcc ≤ +5.25V.
