The SN65C23243 and SN75C23243 consist of
24
25
two ports, each containing three line drivers and
five line receivers, and a dual charge-pump circuit
with ±15-kV ESD protection pin to pin (serial-port
connection pins, including GND). These devices meet the requirements of TIA/EIA-232-F and provide the
electrical interface between an asynchronous communication controller and the serial-port connector. This
combination of drivers and receivers matches that needed for two typical serial ports used in an IBM PC/AT, or
compatible. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V
supply. In addition, these devices include an always-active noninverting output (ROUT2) per port, which allows
applications using the ring indicator to transmit data while the devices are powered down. The devices operate
at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew-rate.

description/ordering information (continued)
Flexible control options for power management are available when either or both serial ports are 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 of its respective port are
disabled. If FORCEOFF is set low, both drivers and receivers (except ROUT2) are shut off, and the supply
current is reduced to 1 µA. Disconnecting the serial port or turning off the peripheral drivers causes the
auto-powerdown condition to occur.
Auto-powerdown can be disabled when FORCEON and FORCEOFF are high and should be done when driving
a serial mouse. With auto-powerdown enabled, the RS-232 port is activated automatically when a valid signal
is applied to any respective receiver input. The INV output is used to notify the user if an RS-232 signal is present
at any receiver input. INV 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. INV is low (invalid data) if all receiver input voltages
are between −0.3 V and 0.3 V for more than 30 µs. Refer to Figure 5 for receiver input levels.

Figure 1 shows how the two independent serial ports can be enabled or disabled. As shown by the logic states,
depending on the FORCEOFF, FORCEON, and receiver input levels, either port can be powered down.
Intermediate receiver input levels indicate a 0-V input. Also, it is assumed a pulldown resistor to ground is used
for the receiver outputs. The INV pin goes low when its respective receiver input does not supply a valid RS-232
level. For simplicity, voltage levels, timing differences, and input/output edge rates are not shown.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages are with respect to network GND.
2. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
