DS34C86M

HGSEMI · RS-485 / RS-422 ICs · SOP-16

DS34C86M from HGSEMI, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN_A- input Receiver A inverting differential input. Part of the balanced RS-422/RS-423 pair for channel A; ±0.2 V sensitivity over ±7 V common mode.
2 IN_A+ input Receiver A non-inverting differential input. Part of the balanced RS-422/RS-423 pair for channel A.
3 OUT_A tri_state Receiver A TRI-STATE CMOS output. Sources/sinks 6 mA; enabled by TRI-STATE CONTROL A/C (pin 4).
4 EN_AC input TRI-STATE CONTROL A/C enable input. Independently enables the output buffers of receivers A and C. VIH = 2.0 V min, VIL = 0.8 V max; input rise/fall time ≤ 500 ns.
5 OUT_C tri_state Receiver C TRI-STATE CMOS output. Sources/sinks 6 mA; enabled by TRI-STATE CONTROL A/C (pin 4).
6 IN_C+ input Receiver C non-inverting differential input. Balanced RS-422/RS-423 pair for channel C.
7 IN_C- input Receiver C inverting differential input. Balanced RS-422/RS-423 pair for channel C.
8 GND power_in Ground reference for the device (0 V).
9 IN_D- input Receiver D inverting differential input. Balanced RS-422/RS-423 pair for channel D.
10 IN_D+ input Receiver D non-inverting differential input. Balanced RS-422/RS-423 pair for channel D.
11 OUT_D tri_state Receiver D TRI-STATE CMOS output. Sources/sinks 6 mA; enabled by TRI-STATE CONTROL B/D (pin 12).
12 EN_BD input TRI-STATE CONTROL B/D enable input. Independently enables the output buffers of receivers B and D. VIH = 2.0 V min, VIL = 0.8 V max; input rise/fall time ≤ 500 ns.
13 OUT_B tri_state Receiver B TRI-STATE CMOS output. Sources/sinks 6 mA; enabled by TRI-STATE CONTROL B/D (pin 12).
14 IN_B+ input Receiver B non-inverting differential input. Balanced RS-422/RS-423 pair for channel B.
15 IN_B- input Receiver B inverting differential input. Balanced RS-422/RS-423 pair for channel B.
16 VCC power_in Positive supply input. Operating range 4.75 V to 5.25 V (5 V nominal); ICC ≈ 12 mA typical.
