CC
:
3.3V Input Supply Pin. Supply current 0.2
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 which reduces
the supply current to 0.2
μ
A and places all drivers and
receivers in high impedance state. This pin cannot float.
V
+
:
Positive Supply Output (EIA/TIA-562 Drivers).
V
+
2V
CC
– 1V. This pin requires an external capacitor
U
C = 0.1
μ
F for charge storage. The capacitor may be tied to
ground or 3.3V. 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 (EIA/TIA-562 Drivers).
V
– (2V
CC
– 1.3). This pin requires an external capacitor
C = 0.1

F for a charge storage.
