ADM3068EBRZ

Analog Devices · RS-485/RS-422 ICs · SOIC-14

ADM3068EBRZ from Analog Devices, in a SOIC-14. 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 VIO power_in 1.62 V to 5.5 V logic supply; a 0.1 µF decoupling capacitor to GND is recommended.
2 RO output Receiver output data, high when (A − B) ≥ −30 mV and low when (A − B) ≤ −200 mV, tristated when RE is driven high.
3 DE input Driver enable; a high level enables driver outputs Y and Z and a low level places them in high impedance.
4 RE input Active-low receiver enable; driving low enables the receiver and driving high disables it.
5 DI input Transmit data input; data to be transmitted by the driver is applied to this input.
6 GND power_in Ground.
7 NIC unconnected No internal connection; this pin is not internally connected.
8 GND power_in Ground.
9 Y output Driver noninverting output, put into high impedance when the driver is disabled or VCC is powered down.
10 Z output Driver inverting output, put into high impedance when the driver is disabled or VCC is powered down.
11 B input Inverting receiver input.
12 A input Noninverting receiver input.
13 NIC unconnected No internal connection; this pin is not internally connected.
14 VCC power_in 3.0 V to 5.5 V power supply; a 0.1 µF decoupling capacitor to GND is recommended.
