DS34LV87TM

Texas Instruments · RS-485 / RS-422 ICs · SOIC-16

DS34LV87TM from Texas Instruments, in a SOIC-16. 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 DI1 input Driver 1 input, LVTTL/LVCMOS compatible with VIH 2.0V min and VIL 0.8V max, protected by ESD diodes.
2 DO1+ output Driver 1 non-inverting differential output, TRI-STATE when EN is low, RS-422 compliant with ESD of 7 kV or more (HBM).
3 DO1- output Driver 1 inverting differential output, TRI-STATE when EN is low, RS-422 compliant with ESD of 7 kV or more (HBM).
4 EN input Enable input for drivers 1 and 2; outputs are TRI-STATE when low and active when high.
5 DO2- output Driver 2 inverting differential output, TRI-STATE when EN is low, RS-422 compliant with ESD of 7 kV or more (HBM).
6 DO2+ output Driver 2 non-inverting differential output, TRI-STATE when EN is low, RS-422 compliant with ESD of 7 kV or more (HBM).
7 DI2 input Driver 2 input, LVTTL/LVCMOS compatible with VIH 2.0V min and VIL 0.8V max, protected by ESD diodes.
8 GND power_in Ground reference for the device.
9 DI3 input Driver 3 input, LVTTL/LVCMOS compatible with VIH 2.0V min and VIL 0.8V max, protected by ESD diodes.
10 DO3+ output Driver 3 non-inverting differential output, TRI-STATE when EN is low, RS-422 compliant with ESD of 7 kV or more (HBM).
11 DO3- output Driver 3 inverting differential output, TRI-STATE when EN is low, RS-422 compliant with ESD of 7 kV or more (HBM).
12 EN input Enable input for drivers 3 and 4; outputs are TRI-STATE when low and active when high.
13 DO4- output Driver 4 inverting differential output, TRI-STATE when EN is low, RS-422 compliant with ESD of 7 kV or more (HBM).
14 DO4+ output Driver 4 non-inverting differential output, TRI-STATE when EN is low, RS-422 compliant with ESD of 7 kV or more (HBM).
15 DI4 input Driver 4 input, LVTTL/LVCMOS compatible with VIH 2.0V min and VIL 0.8V max, protected by ESD diodes.
16 VCC power_in Supply voltage of 3.0V to 3.6V (3.3V typical), with 0.1 µF in parallel with 0.01 µF bypass recommended.
