VCC: 5V Input Supply Pin. Supply current drops to zero in  
the shutdown mode. This pin should be decoupled with a  
0.1µF ceramic capacitor close to the package pin. Insuffi-

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.  
GND: Ground Pin.

ON/OFF: Control the operation mode of the device and is

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.  
DRIVER DISABLE: This pin provides an alternate control  
for the charge pump and RS232 drivers. A logic high on
