7.4 Device Functional Modes
Table 7-1 Driver
| INPUTS(1) | OUTPUT | DRIVER STATUS | |||
|---|---|---|---|---|---|
| DIN | FORCEON | FORCEOFF | VALID RIN RS-232 LEVEL | DOUT | |
| X | X | L | X | Z | Powered off |
| L | H | H | X | H | Normal operation with automatic power down disabled |
| H | H | H | X | L | |
| L | L | H | Yes | H | Normal operation with automatic power down enabled |
| H | L | H | Yes | L | |
| L | L | H | No | Z | Powered off by automatic power-down feature |
| H | L | H | No | Z | |
(1) H = high level, L = low level, X = irrelevant, Z = high impedance, Yes = |RIN| > 2.7 V, No = |RIN| < 0.3 V
Table 7-2 Receiver
| INPUTS(1) | OUTPUT | RECEIVER STATUS | ||
|---|---|---|---|---|
| RIN | EN | VALID RIN RS-232 LEVEL | ROUT | |
| X | H | X | Z | Output off |
| L | L | X | H | Normal operation |
| H | L | X | L | |
| Open | L | No | H | |
(1) H = high level, L = low level, X = irrelevant, Z = high impedance (off), Open = input disconnected or connected driver off
