TRSF3243 SLLS862B – AUGUST 2007 – REVISED OCTOBER 2022 3-V to 5.5-V Multichannel RS-232 Compatible Line Driver and Receiver 1 Features 3 Description • • The TRSF3243 consists of three line drivers, five line receivers, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND). This device provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. In addition, this device includes an always-active noninverting output (ROUT2B), which allows applications using the ring indicator to transmit data while the device is powered down. The device operates at data signaling rates up to 1 Mbit/s and an increased slew-rate range of 24 V/μs to 150 V/μs. • • • • • • Operates with 3-V to 5.5-V VCC supply Always-active noninverting receiver output (ROUT2B) Low standby current: 1 μA typical External capacitors: 4 × 0.1 μF Accepts 5-V logic input with 3.3-V supply Inter-operable with SN65C3238, SN75C3238 Supports operation from 250 kbit/s to 1 Mbit/s RS-232 Bus-pin esd protection exceeds ±15 kV using human-body model (HBM) 2 Applications • • • • • • Battery-powered systems PDAs Notebooks Laptops Palmtop PCs Hand-held equipment Package Information PACKAGE(1) PART NUMBER TRS3243 (1) 3.3 V, 5 V BODY SIZE (NOM) SSOP (DB) 10.20 mm × 5.30 mm SOIC (DW) 17.90 mm x 7.50mm TSSOP (PW) 9.70 mm × 4.40 mm For all available packages, see the orderable addendum at the end of the data sheet.

The autopowerdown 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, both drivers and receivers (except ROUT2B) 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 device is activated automatically 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 all receiver input voltages are between –0.3 V and 0.3 V for more than 30 μs. Refer to Figure 7-5 for receiver input levels. 7.2 Device Functional Modes 7.2.1 Function Tables EACH DRIVER(1) INPUTS (1) OUTPUT DOUT DRIVER STATUS X Z Powered off DIN FORCEON FORCEOFF VALID RIN RS-232 LEVEL X X L L H H X H H H H X L L L H Yes H H L H Yes L L L H No Z H L H No Z Normal operation with auto-powerdown disabled Normal operation with auto-powerdown enabled Powered off by auto-powerdown feature H = high level, L = low level, X = irrelevant, Z = high impedance EACH RECEIVER(1) INPUTS RIN1, RIN3–RIN5 RIN2 (1) 12 OUTPUTS FORCEOFF VALID RIN RS-232 LEVEL ROUT2B ROUT2 ROUT1, ROUT3–5 L X L X L Z Z H X L X H Z Z L L H YES L H H L H H YES L L L H L H YES H H H H H H YES H L L Open Open H YES L H H RECEIVER STATUS Powered off while ROUT2B is active Normal operation with auto-powerdown disabled/enabled H = high level, L = low level, X = irrelevant, Z = high impedance (off), Open = input disconnected or connected driver off Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated Product Folder Links: TRSF3243 TRSF3243 www.ti.com SLLS862B – AUGUST 2007 – REVISED OCTOBER 2022 DIN1 DIN2 DIN3 FORCEOFF 14 9 DOUT1 13 10 DOUT2 12 11 DOUT3 22 21 23 INVALID Auto-Powerdown FORCEON ROUT1 19 4 RIN1 20 ROUT2B ROUT2 18 5 RIN2 17 6 ROUT3 ROUT4 ROUT5 RIN3 7 16 RIN4 15 8 RIN5 Figure 7-1.

Tools and software to evaluate the performance of the device, generate code, and develop solutions are listed below. 8.1 Receiving Notification of Documentation Updates To receive notification of documentation updates, navigate to the device product folder on ti.com. Click on Subscribe to updates to register and receive a weekly digest of any product information that has changed. For change details, review the revision history included in any revised document. 8.2 Support Resources TI E2E™ support forums are an engineer's go-to source for fast, verified answers and design help — straight from the experts. Search existing answers or ask your own question to get the quick design help you need. Linked content is provided "AS IS" by the respective contributors. They do not constitute TI specifications and do not necessarily reflect TI's views; see TI's Terms of Use. 8.3 Trademarks TI E2E™ is a trademark of Texas Instruments. All trademarks are the property of their respective owners. 8.4 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 8.5 Glossary TI Glossary This glossary lists and explains terms, acronyms, and definitions. 9 Mechanical, Packaging, and Orderable Information The following pages include mechanical, packaging, and orderable information.
