DESCRIPTION/
ORDERING INFORMATION
The TRSF3223E consists of two line drivers, two line
receivers, and a dual charge-pump circuit with
15-kV ESD protection pin to pin (serial-port
connection pins, including GND). This device meets
the requirements of TIA/EIA-232-F and provides the
electrical
interface
between
communication
controller
and
connector. The charge pump and four small external
capacitors allow operation from a single 3-V to 5.5-V
supply. The TRSF3223E operates at typical data
signaling rates up to 1000 kbit/s.
Flexible control options for power management are available when the serial port is inactive. The
auto-powerdown feature functions when FORCEON is low and FORCEOFF is high. During this mode of
operation, if the device does not sense a valid RS-232 signal, the driver outputs are disabled. If FORCEOFF is
set low and EN is high, both drivers and receivers are shut off, and the supply current is reduced to 1 mA.
Disconnecting the serial port or turning off the peripheral drivers causes auto-powerdown to occur.
Auto-powerdown can be disabled when FORCEON and FORCEOFF are high. With auto-powerdown enabled,
the device is automatically activated when a valid signal is applied to any receiver input. The INVALID output is
used to notify the user if an RS-232 signal is present at any receiver 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 μs. INVALID is low (invalid data) if the receiver input voltage is between –0.3 V and 0.3 V for more than
30 μs. Refer to Figure 4 for receiver input levels.
