TYPICAL PERFOR
CE
V
CC
:
5V Input Supply Pin. This pin should be decoupled
with a 0.1
μ
F ceramic capacitor close to the package pin.
Insufficient supply bypassing can result in low output
drive levels and erratic charge pump operation.
V
L
:
3V Logic Supply Pin for all RS232 Receivers. Like V
CC
,
the V
L
input should be decoupled with a 0.1
μ
F ceramic
capacitor. This pin may also be connected to 5V.
GND:
Ground Pin.
ON/OFF:
TTL/CMOS Compatible Operating Mode Control.
A logic low puts the device in the low power shutdown
mode. All three drivers and four receivers (RX1, RX2, RX3,
and RX4) assume a high impedance output state in shut-
down. Only receiver RX5 remains active while the trans-
ceiver is in shutdown. The transceiver consumes only
PI FU
U
60
μ
A of supply current while in shutdown. 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 driver
outputs in a high impedance state. All five 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
3mA when in driver disable mode.

– 1.5V. This pin
requires an external charge storage capacitor, C
