PRODUCTION DATA
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
C1+ | 2 | — | Positive terminals of the voltage-doubler charge pump capacitors |
C2+ | 5 | ||
C1– | 4 | — | Negative terminals of the voltage-doubler charge pump capacitors |
C2– | 6 | ||
DIN | 11 | I | Driver input |
DOUT | 13 | O | RS-232 driver output |
EN | 1 | I | Low input enables receiver ROUT output. High input sets ROUT to high impedance. |
FORCEOFF | 16 | I | Automatic power-down control input |
FORCEON | 12 | I | Automatic power-down control input |
GND | 14 | — | Ground |
INVALID | 10 | O | Invalid output pin. Output low when RIN input is unpowered. |
RIN | 8 | I | RS-232 receiver input |
ROUT | 9 | O | Receiver output |
VCC | 15 | — | 3V to 5.5V supply voltage |
V+ | 3 | O | 5.5V supply generated by the charge pump |
V– | 7 | O | –5.5V supply generated by the charge pump |
