CC
:
5V Input Supply Pin. Supply current is typically 80
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 the shutdown mode with all receiv-
ers kept alive, and the supply current is 80
μ
A. All driver
outputs are in high impedance state. This pin cannot float.
V
+
:
Positive Supply Output (RS232 Drivers).
V
+
2V
CC
– 1V. This pin requires an external capacitor C
U
= 0.1
μ
F for charge storage. The capacitor may be tied to
ground or V
CC
. With multiple devices, the V
+
and V
pins
may be paralleled into common capacitors. For large
numbers of devices, increasing the size of the shared
common storage capacitors is recommended to reduce
ripple.
V
:
Negative Supply Output (RS232 Drivers).
V
– (2V
CC
– 1.5V). This pin requires an external
capacitor C = 0.1
μ
F for charge storage.
