Supply current drops to zero in the shutdown mode. This pin should be decoupled with a 0.1 µF ceramic capacitor close to the package pin. Insuffi- cient supply bypassing can result in low output drive levels and erratic charge pump operation. GND: Ground Pin. ON/OFF: Control the operation mode of the device and is TTL/CMOS compatible. A logic low puts the device in the shutdown mode which reduces input supply curent to zero and places all of the drivers and receivers in high imped- ance state. A logic high fully enables the transceiver. DRIVER DISABLE: This pin provides an alternate control for the charge pump and RS232 drivers. A logic high on this pin shuts down the charge pump and places all drivers in a high impedance state. Receivers remain active under these conditions. Floating the DRIVER DISABLE pin or driving it to a logic low level fully enables the transceiver. A logic low on the ON/OFF pin supersedes the state of the DRIVER DISABLE pin. Supply current drops to 4mA when in driver disable mode. V+: Positive Supply Output (RS232 Drivers). V+ ≈ 2VCC – 1.5V. This pin requires an external charge storage capaci- tor C ≥ 1.0µF, tied to ground or VCC. Larger value capaci- tors may be used to reduce supply ripple. With multiple transceivers, the V + and V – pins may be paralleled into common capacitors. For large numbers of transceivers, increasing the size of the shared common storage capaci- tors is recommended to reduce ripple.
