MAX13487EESA+T-JSM

JSMSEMI · RS-485 / RS-422 ICs · SOP-8

MAX13487EESA+T-JSM from JSMSEMI, in a SOP-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: RO is high if A-B ≥ -50mV and low if A-B ≤ -200mV when the receiver is enabled.
2 /RE input Receiver output enable, active low: RO is enabled when /RE is low, and when /RE is high the auto-direction control circuit controls the receiver; /RE is a hot-swap input.
3 /SHDN input Shutdown enable: device operates normally when /SHDN is high and enters low-power shutdown mode when /SHDN is low.
4 DI input Driver input: low forces the non-inverting output low and inverting output high, high forces the reverse; DI also feeds the internal state machine that controls driver enable, and is a hot-swap input.
5 GND power_in Ground.
6 A bidirectional Non-inverting receiver input and non-inverting driver output.
7 B bidirectional Inverting receiver input and inverting driver output.
8 VCC power_in Positive supply, 4.5V ≤ VCC ≤ 5.5V, with a 0.1µF capacitor connected between VCC and GND.
