HT6506ARZ

HTCSEMI · RS-485/RS-422 ICs · SOP-8

HT6506ARZ from HTCSEMI, 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, three-state, driven high if the A/B inputs are open, and high impedance when RE is high; limited to -0.3V to (VCC+0.3V).
2 RE input Active-low receiver output enable; RE low enables the receiver and RE high puts RO in high impedance, with VIH min 2.0V and VIL max 0.8V.
3 DE input Driver output enable; DE high enables the driver outputs and DE low puts them in high impedance, with VIH min 2.0V and VIL max 0.8V.
4 DI input Driver input; a low on DI with the driver enabled drives the non-inverting output low and the inverting output high, rated -0.3V to 7V.
5 GND power_in Ground reference for all device voltages.
6 A bidirectional Bus line A, serving as both receiver input and driver output, rated -7.5V to +12.5V.
7 B bidirectional Bus line B, serving as both receiver input and driver output, rated -7.5V to +12.5V.
8 VCC power_in Single 3.3V supply input (3.3V ±0.3V operating), with an absolute maximum of 7V.
