TPT75176H-VS1R

3PEAK · Global Sourcing Parts · MSOP-8

TPT75176H-VS1R from 3PEAK, in a MSOP-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: drives valid bus High when VID is above VIT+ and valid bus Low when VID is below VIT-, and goes high-Z when RE is high; outputs are rated for high drive (typically >25mA at VOL = 1V).
2 RE input Active-low receiver enable: RE low enables the receiver output, and RE high disables it to high-Z; logic input with VIH of 2V minimum and VIL of 0.8V maximum.
3 DE input Driver enable: DE high enables the driver outputs A and B, and DE low (or open, which defaults to disabled) puts them in high-Z; logic input with VIH of 2V minimum and VIL of 0.8V maximum.
4 D input Driver data input: D high drives A high and B low, and D low drives A low and B high when DE is high; logic input with VIH of 2V minimum and VIL of 0.8V maximum, and absolute maximum of VCC + 0.3V.
5 GND power_in Ground reference for the device supply (VDD to GND absolute maximum range is -0.3V to +7V).
6 A bidirectional Non-inverting RS-485 bus pin: bus common-mode range is -7V to +12V, with ±15 kV HBM and ±15 kV IEC-ESD protection and an input/output absolute voltage range of -15V to +15V.
7 B bidirectional Inverting RS-485 bus pin: bus common-mode range is -7V to +12V, with ±15 kV HBM and ±15 kV IEC-ESD protection and an input/output absolute voltage range of -15V to +15V.
8 VCC power_in Supply voltage: 3V to 5.5V recommended operating range; the device keeps its Tx and Rx outputs disabled when VCC is below about 2.5V (Hot Plug).
