(tri-stated) and the charge pump is turned
off with V+ pulled down to Vcc and V- pulled
to GND. The time required to exit shutdown
is typically 100ms. Connect SHDN to Vcc if
the shutdown mode is not used. SHDN has
no effect on RxOUT. Note that the driver is
enabled only when the magnitude of V- ex-
ceeds approximately 3V.
Receiver
The receiver converts EIA/TIA-232 levels
to TTL or CMOS logic output levels. The
receiver has an inverting high-impedance
output. This receiver output (RxOUT) is at
high-impedance when the enable control
EN = HIGH. In the shutdown mode, the
receiver can be active or inactive. EN has
no effect on TxOUT. The truth table logic
of the
SP3220E/EB/EU driver and receiver
outputs can be found in Table 2.

Shutdown and Enable Control

Circuit
Since receiver input is usually from a trans-
mission line where long cable lengths and
system interference can degrade the signal,
the inputs have a typical hysteresis margin
of 300mV. This ensures that the receiver
is virtually immune to noisy transmission
lines. Should an input be left unconnected,
an internal 5K pulldown resistor to ground
will commit the output of the receiver to a
HIGH state.
