SP483EN-L

MaxLinear · Pre-ordered Chips · SOIC-8

SP483EN-L from MaxLinear, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RO output Receiver output, tri-stated when RE is HIGH and driven HIGH when the A/B inputs are open (fail-safe).
2 RE input Receiver output enable, active LOW; a logic HIGH disables the receiver, and RE HIGH with DE LOW puts the SP483 into Shutdown mode.
3 DE input Driver output enable, active HIGH; a logic LOW tri-states the driver outputs, and DE LOW with RE HIGH puts the SP483 into Shutdown mode.
4 DI input Driver input, with a logic level input high of 2.0V minimum and low of 0.8V maximum.
5 GND power_in Ground connection.
6 A bidirectional Non-inverting driver output and receiver input, with a -7V to +12V receiver common mode range.
7 B bidirectional Inverting driver output and receiver input, with a -7V to +12V receiver common mode range.
8 VCC power_in Positive supply, 4.75V ≤ Vcc ≤ 5.25V (absolute maximum +7V).
