Product Details
MAX3232ECUE+T - Maxim ±15kV ESD-Protected +3V to +5.5V RS-232 Transceiver, 2-Tx/2-Rx (TSSOP-16)
The MAX3232ECUE+T from Maxim Integrated (Analog Devices) is the TSSOP version of the ±15kV ESD-protected MAX3232E RS-232 transceiver - two drivers, two receivers, +3V to +5.5V, with the slim 16-pin TSSOP body for height- and space-constrained boards. A dual charge pump and 0.1µF capacitors deliver true RS-232 from 3.3V, with ±15kV ESD on the I/O.
Product Introduction
The MAX3232ECUE+T is the slim-TSSOP grade of Maxim's ±15kV ESD-protected MAX3232E RS-232 transceiver (MAX3222E-MAX3241E family). It delivers two drivers and two receivers from a +3V to +5.5V supply, with the same electrical performance as the SSOP MAX3232ECAE but in the lower-profile 16-pin TSSOP outline preferred for thin and dense assemblies.
A dual charge pump makes the RS-232 line levels from 3.3V using only 0.1µF capacitors, and every RS-232 input/output is hardened to ±15kV Human Body Model ESD. The receivers carry a 5kΩ input pulldown and translate RS-232 to TTL/CMOS.
Sharing the universal MAX3232E pinout, the TSSOP MAX3232ECUE drops into any MAX3232E layout where the thinner TSSOP package is needed - notebooks, hand-held terminals and compact peripherals whose serial connector is exposed to ESD.
Expert Technical Insight
Why the TSSOP MAX3232ECUE?
- Low-profile TSSOP: the 16-pin TSSOP is thinner and narrower than the SSOP, fitting tight, low-height assemblies while keeping the full MAX3232E function.
- 3.3V RS-232 + ±15kV ESD: true RS-232 levels from a 3.3V rail with ±15kV HBM on the connector pins - the modern low-voltage, ESD-robust combination.
- 0.1µF, shared pinout: small 0.1µF charge-pump capacitors and the common MAX3232E pinout make it a drop-in for SSOP/TQFN siblings.
Key Benefits
Thin 16-pin TSSOP for height- and space-constrained boards.
±15kV HBM ESD on all RS-232 I/O pins.
True RS-232 from 3.3V via dual charge pump; only 0.1µF capacitors.
Two Tx + two Rx; common MAX3232E pinout across SSOP/TSSOP/TQFN.

Package Information
The MAX3232ECUE+T is supplied in a 16-pin TSSOP package, indicated by the CUE suffix - a thinner, narrower body than the SSOP MAX3232ECAE while sharing the identical MAX3232E pinout.
The "+" suffix indicates lead-free, RoHS-compliant finish and the "T" suffix tape-and-reel packing. Standard 16-lead TSSOP land patterns and reflow profiles apply; place the four 0.1µF charge-pump capacitors and VCC bypass close to the device. The diagram below shows the typical operating circuit.
Pin Configuration (TSSOP-16)
The MAX3232E uses a 16-pin RS-232 pinout (top view):
- Pin 1 - C1+ / Pin 3 - C1- / Pin 4 - C2+ / Pin 5 - C2-: Charge-pump capacitor connections.
- Pin 2 - V+ / Pin 6 - V-: Charge-pump outputs (+5.5V / -5.5V).
- Pin 11 - T1IN / Pin 10 - T2IN: Driver TTL/CMOS inputs.
- Pin 14 - T1OUT / Pin 7 - T2OUT: Driver RS-232 outputs (±15kV ESD).
- Pin 13 - R1IN / Pin 8 - R2IN: Receiver RS-232 inputs (±15kV ESD, 5kΩ pulldown).
- Pin 12 - R1OUT / Pin 9 - R2OUT: Receiver TTL/CMOS outputs.
- Pin 15 - GND / Pin 16 - VCC: Ground and +3V-+5.5V supply.
Connect the four 0.1µF capacitors, route T_IN/R_OUT to the UART and the ESD-protected T_OUT/R_IN to the RS-232 connector. Confirm the exact pin assignment against the datasheet image below before layout.
