Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | C1+ | passive | Positive terminal of the voltage-doubler flying capacitor; connect a 0.1µF capacitor between C1+ and C1− for +3.3V operation (see Table 2 for other supply voltages). |
| 2 | V+ | power_out | Internal charge-pump positive supply output, nominally +5.5V; connect 0.1µF reservoir capacitor C3 from V+ to GND. |
| 3 | C1- | passive | Negative terminal of the voltage-doubler flying capacitor; connect a 0.1µF capacitor between C1+ and C1−. |
| 4 | C2+ | passive | Positive terminal of the inverting charge-pump flying capacitor; connect a 0.1µF capacitor between C2+ and C2−. |
| 5 | C2- | passive | Negative terminal of the inverting charge-pump flying capacitor; connect a 0.1µF capacitor between C2+ and C2−. |
| 6 | V- | power_out | Internal charge-pump negative supply output, nominally −5.5V; connect 0.1µF reservoir capacitor C4 from V− to GND. |
| 7 | T2OUT | output | RS-232 transmitter output 2 (inverting); ±5V minimum swing into 3kΩ load (typ ±5.4V), 250kbps guaranteed, ±15kV ESD-protected (HBM), short-circuit current ±60mA continuous. |
| 8 | R2IN | input | RS-232 receiver input 2; accepts ±25V input range, 3kΩ-7kΩ input resistance, input threshold low 0.6-1.5V / high 1.5-2.4V (VCC = +3.3V), ±15kV ESD-protected (HBM, IEC 1000-4-2). |
| 9 | R2OUT | output | TTL/CMOS receiver output 2 (inverting); VOL ≤ 0.4V at IOUT = 1.6mA, VOH ≥ VCC−0.6V at IOUT = −1.0mA. |
| 10 | T2IN | input | TTL/CMOS transmitter input 2; VIL ≤ 0.8V, VIH ≥ 2.0V at VCC = +3.3V (2.4V at +5V), 0.5V hysteresis; connect to GND or VCC if unused. |
| 11 | T1IN | input | TTL/CMOS transmitter input 1; VIL ≤ 0.8V, VIH ≥ 2.0V at VCC = +3.3V (2.4V at +5V), 0.5V hysteresis; connect to GND or VCC if unused. |
| 12 | R1OUT | output | TTL/CMOS receiver output 1 (inverting); VOL ≤ 0.4V at IOUT = 1.6mA, VOH ≥ VCC−0.6V at IOUT = −1.0mA. |
| 13 | R1IN | input | RS-232 receiver input 1; accepts ±25V input range, 3kΩ-7kΩ input resistance, 0.5V input hysteresis, ±15kV ESD-protected (HBM, IEC 1000-4-2). |
| 14 | T1OUT | output | RS-232 transmitter output 1 (inverting); ±5V minimum swing into 3kΩ load (typ ±5.4V), 250kbps guaranteed, ±15kV ESD-protected (HBM), output resistance ≥300Ω when VCC = 0V. |
| 15 | GND | power_in | Ground (0V) reference for all internal circuitry and charge-pump returns. |
| 16 | VCC | power_in | +3.0V to +5.5V supply voltage; typical quiescent current 1mA (max), bypass with 0.1µF capacitor placed close to the IC. |
