V
CC
:
5V Input Supply Pin. Supply current is typically 35
μ
A
in the SHUTDOWN mode. This pin should be decoupled
with a 0.1
μ
F ceramic capacitor.
GND:
Ground Pin.
ON/OFF:
TTL/CMOS Compatible SHUTDOWN Pin. A logic
low puts the device in SHUTDOWN mode, with receivers
4 and 5 kept alive and the supply current equal to 35
μ
A. All
driver outputs and other receiver outputs are in high
impedance state. This pin can not float.
V
+
:
Positive Supply Output (RS232 Drivers). V
+
2V
CC
–
1V. This pin requires an external capacitor C = 0.1
μ
F for
charge storage. The capacitor may be tied to ground or 5V.

pins may be paral-
leled into common capacitors. For large numbers of de-
vices, increasing the size of the shared common storage
capacitors is recommended to reduce ripple.
