Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Receiver enable input: when EN is high the receiver outputs ROUT are forced high-impedance, and logic inputs accept 0 V to 5.5 V with VIL max 0.8 V and VIH min 2.4 V at VCC = 5 V. |
| 2 | C1+ | passive | Positive terminal of charge-pump flying capacitor C1, which is 0.1 µF at VCC = 3.3 V or 0.047 µF at VCC = 5 V with nonpolarized ceramic capacitors acceptable. |
| 3 | V+ | power_out | Positive charge-pump output that supplies the RS-232 driver, with an absolute maximum of −0.3 V to 7 V and a V+ to V− difference of 13 V maximum. |
| 4 | C1− | passive | Negative terminal of charge-pump flying capacitor C1, connected across C1+ with the same 0.1 µF or 0.047 µF value depending on VCC. |
| 5 | C2+ | passive | Positive terminal of charge-pump flying capacitor C2, which is 0.1 µF at VCC = 3.3 V or 0.33 µF at VCC = 5 V. |
| 6 | C2− | passive | Negative terminal of charge-pump flying capacitor C2, connected across C2+ with the same value as C2. |
| 7 | V− | power_out | Negative charge-pump output that supplies the RS-232 driver, with an absolute maximum magnitude of 7 V and a V+ to V− difference of 13 V maximum. |
| 8 | DOUT2 | output | RS-232 driver 2 output, rated to ±13.2 V absolute maximum and protected to ±15 kV HBM ESD. |
| 9 | RIN2 | input | RS-232 receiver 2 input, rated to ±25 V with a 3 kΩ to 5 kΩ input resistance and ±15 kV HBM ESD protection. |
| 10 | ROUT2 | output | Receiver 2 CMOS output that swings to VCC − 0.1 V minimum high at IOH = −1 mA and goes high-impedance when EN is high. |
| 11 | INVALID | output | Output that is high when any receiver input exceeds ±2.7 V or has been between −0.3 V and 0.3 V for less than 30 µs, and low when the input stays within that band for more than 30 µs. |
| 12 | DIN2 | input | Driver 2 logic input that accepts 5 V logic levels with a 3.3 V supply, with the input range 0 V to 5.5 V. |
| 13 | DIN1 | input | Driver 1 logic input that accepts 5 V logic levels with a 3.3 V supply, with the input range 0 V to 5.5 V. |
| 14 | FORCEON | input | Auto-powerdown control input: with FORCEON low and FORCEOFF high auto-powerdown is enabled, and with FORCEON and FORCEOFF both high it is disabled. |
| 15 | ROUT1 | output | Receiver 1 CMOS output that swings to VCC − 0.1 V minimum high at IOH = −1 mA and goes high-impedance when EN is high. |
| 16 | RIN1 | input | RS-232 receiver 1 input, rated to ±25 V with a 3 kΩ to 5 kΩ input resistance and ±15 kV HBM ESD protection. |
| 17 | DOUT1 | output | RS-232 driver 1 output, rated to ±13.2 V absolute maximum and protected to ±15 kV HBM ESD. |
| 18 | GND | power_in | Network ground, to which all voltages are referenced. |
| 19 | VCC | power_in | Supply voltage input, which operates from 3 V to 3.6 V (3.3 V nominal) or 4.5 V to 5.5 V (5 V nominal) with an absolute maximum of 6 V. |
| 20 | FORCEOFF | input | Active-low shutdown input: when low, both drivers and receivers are shut off and the supply current drops to 1 µA typical, with a 0 V to 5.5 V input range. |
