DESCRIPTION/ORDERING INFORMATION (CONTINUED)
MAX3238E
3-V TO 5.5-V MULTICHANNEL RS-232 LINE DRIVER/RECEIVER
WITH ± 15-kV ESD (HBM) PROTECTION
SLLS710A – FEBRUARY 2006 – REVISED APRIL 2006
Flexible control options for power management are featured when the serial port and driver inputs are inactive.
The auto-powerdown plus feature functions when FORCEON is low and FORCEOFF is high. During this mode
of operation, if the device does not sense valid signal transitions on all receiver and driver inputs for
approximately 30 s, the built-in charge pump and drivers are powered down, reducing the supply current to
1 µ A. By disconnecting the serial port or placing the peripheral drivers off, auto-powerdown plus occurs if there
is no activity in the logic levels for the driver inputs. Auto-powerdown plus can be disabled when FORCEON and
FORCEOFF are high. With auto-powerdown plus enabled, the device activates automatically when a valid signal
is applied to any receiver or driver input. INVALID is high (valid data) if any receiver input voltage is greater than
2.7 V or less than –2.7 V, or has been between –0.3 V and 0.3 V for less than 30 µ s. INVALID is low (invalid
data) if all receiver input voltages are between –0.3 V and 0.3 V for more than 30 µ s. Refer to Figure 5 for
receiver input levels.
