TPT75176A-SO1R

3PEAK · Buffers, Drivers, Receivers, Transceivers · SOP-8

TPT75176A-SO1R from 3PEAK, 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 R output Receiver output, driven high when A-B is above VIT+ or inputs are open/shorted/terminated (full fail-safe), high-Z when /RE is high; VOL 0.4 V max at IOL = 8 mA.
2 RE input Receiver enable, active low (/RE); logic low enables the receiver and high puts R in high-impedance, with VIH 2 V min and VIL 0.8 V max.
3 DE input Driver enable, active high; high enables the driver outputs A/B and low (or open) disables them to high-Z, with VIH 2 V min and VIL 0.8 V max.
4 D input Driver input; with the driver enabled, high drives A high and B low, and low drives A low and B high, with VIH 2 V min and VIL 0.8 V max.
5 GND power_in Ground reference for the device.
6 A bidirectional Non-inverting RS-485 bus pin (driver output / receiver input), range -9 V to +14 V absolute max, ±12 kV HBM ESD.
7 B bidirectional Inverting RS-485 bus pin (driver output / receiver input), range -9 V to +14 V absolute max, ±12 kV HBM ESD.
8 VCC power_in Supply voltage input, 3 V to 5.5 V recommended operating range, -0.3 V to +7 V absolute maximum.
