Product details

Active RS-232 driver for single-supply serial links

The MAX3188EEUT+T: Rated for 250kbps data rate and full-duplex operation, this driver handles typical serial communication with peripherals like barcode scanners, GPS modules, or industrial controllers over standard RS-232 levels.

Supply voltage and signal integrity at the board level

The 4.5V to 6V supply range means it runs from a 5V rail with margin — no charge-pump or dual supplies needed. The 100 mV receiver hysteresis adds noise margin on the input side, which matters when the cable run picks up common-mode noise in an industrial enclosure. Housed in a SOT-23-6 package, the footprint is 2.9 mm × 1.6 mm typical — small enough for a multi-channel RS-232 bank on a compact PCB.

Frequently asked questions

Where can I buy the MAX3188EEUT+T and check availability?

The MAX3188EEUT+T is an active Analog Devices part sourced through independent distribution. Submit an RFQ for current pricing and stock confirmation against your BOM quantity.

What is the data rate of the MAX3188EEUT+T?

The data rate is 250kbps, sufficient for most RS-232 serial peripherals including GPS modules, barcode scanners, and industrial controllers.

What package does the MAX3188EEUT+T come in?

The MAX3188EEUT+T is supplied in a SOT-23-6 surface-mount package, also designated as SOT-6 by the supplier.

What is the equivalent or alternative to the MAX3188EEUT+T?

The MAX3188EEUT+T is a driver-only RS-232 part (1 driver, 0 receivers) — a functional alternative would require a different pinout or a full transceiver like the MAX3232 series, which includes both drivers and receivers.
