Features

The MAX3232ESE from UMW is a stable RS-232 transceiver designed to link serial-port connections to asynchronous communication controllers. The following enumerates its key attributes:

Robust ESD Protection and Compliance:

Features_MAX3232ESE

The MAX3232ESE provides superior electrostatic discharge (ESD) protection, exceeding ±8 kV (HBM) for RS-232 I/O pins. It also meets TIA/EIA-232-F and ITU V.28 standards, ensuring reliable performance and compatibility with industry communication protocols.

Wide Voltage Range and High Data Rate:

It operates over a wide supply voltage range of 3.0V to 5.5V, accommodating various system requirements. With a high driver output slew rate of 35V/μs and support for data signaling rates up to 250 kbit/s, this device enables quick and effective data transmission.

Efficient Charge-Pump Design:

The MAX3232ESE integrates a dual charge-pump circuit that, in conjunction with four small external capacitors (0.1μF each), enables operation from a single voltage supply. This design simplifies circuit requirements and enhances overall efficiency.

Versatile Logic Level Compatibility:

The transceiver can accept 5.0V logic inputs while operating on a 3.3V supply. The fact that it is compatible allows it to be easily integrated into a wide range of digital systems and adapt to varied logic levels.

Package details

The 16-SOIC package that holds the MAX3232ESE has a surface-mount design with a width of 3.90 mm. The device has a small footprint that makes it appropriate for a range of electronic applications because it is packaged in a 16-SOP (Small Outline Package) configuration. With a basic amount of 2500 pieces per reel, it is packaged in tape and reel form, which makes automated placement and efficient handling possible during high-volume manufacturing.
