description/ordering information
The ’C3238 devices consist of five line drivers, three line receivers, and a dual charge-pump circuit with ±15-kV
ESD protection pin to pin (serial-port connection pins, including GND). 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 (ROUT1B), which allows applications using the ring indicator to transmit data while the
device is powered down. These devices operate at data signaling rates up to 1 Mbit/s and at an increased
slew-rate range of 24 V/µs to 150 V/µs.

description/ordering information (continued)
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 30 s, the
built-in charge-pump and drivers are powered down, reducing the supply current to 1 µA. By disconnecting the
serial port or placing the peripheral drivers off, auto-powerdown plus will occur 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 automatically activates once 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 µs. INVALID 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.

† 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.

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)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
