ISL3179EIRZ-T from RENESAS, in a DFN-10-EP(3x3). 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, high if A-B >= -50mV, low if A-B <= -200mV, and high if the inputs are floating, shorted, or on a terminated undriven bus; high impedance when RE is high. |
| 2 | RE | input | Active-low receiver output enable: RO is enabled when RE is low and high impedance when RE is high; connect directly to GND if the Rx enable function is not required. |
| 3 | DE | input | Driver output enable: driver outputs are enabled when DE is high and high impedance when DE is low; if the Tx enable function is not required, connect DE to VCC through a 1kΩ or greater resistor. |
| 4 | DI | input | Driver input: a low forces output Y low and Z high, and a high forces Y high and Z low. |
| 5 | NC | unconnected | No internal connection. |
| 6 | GND | power_in | Ground connection, which is also the potential of the DFN's exposed metal pad. |
| 7 | A/Y | bidirectional | ±16.5kV IEC61000 ESD protected RS-485/RS-422 noninverting receiver input and noninverting driver output; an input (A) if DE = 0 and an output (Y) if DE = 1. |
| 8 | B/Z | bidirectional | ±16.5kV IEC61000 ESD protected RS-485/RS-422 inverting receiver input and inverting driver output; an input (B) if DE = 0 and an output (Z) if DE = 1. |
| 9 | NC | unconnected | No internal connection. |
| 10 | VCC | power_in | System power supply input, 3.0V to 3.6V. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
