ISL3179EIRZ-T

RENESAS · RS-485/RS-422 ICs · DFN-10-EP(3x3)

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).
