description/ordering information
The SN65C23243 and SN75C23243 consist of
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
RIN5B
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.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
