Product details

The Texas Instruments MAX3232EIPWG4 is a full-duplex RS-232 transceiver with two drivers and two receivers, designed to translate between a UART's logic-level signals and the ±5V to ±15V swing required by the RS-232 bus. The 250 kbps data rate covers the majority of legacy serial links (115200 baud and below) with margin, though it will not support higher-speed protocols like RS-232 at 1 Mbps.

Supply range and charge pump — design-in notes

The 16-TSSOP footprint (4.40 mm width) is a space-efficient surface-mount package, but the narrow lead pitch (0.65 mm) demands careful PCB layout and solder-paste stencil design to avoid bridging.

Sourcing reality — obsolete, not end-of-life support

That means no last-time-buy window, no factory production, and no official successor from TI. If you are filling a BOM line for a legacy board, the EIPWG4 is the exact code — we can source it.

Frequently asked questions

Where can I buy MAX3232EIPWG4 and get a price?

Submit an RFQ for current availability and pricing — both confirmed at quote time. No stock figures or prices are published here because supply is sourced per request.

Is MAX3232EIPWG4 obsolete?

Yes, Texas Instruments lists the MAX3232EIPWG4 as Obsolete. It is no longer in factory production. The part can still be sourced through surplus and broker channels while inventory lasts.

Can I use MAX3232EIPWG4 with a 5V supply?

Yes. The supply range is specified from 3V to 5.5V, so a 5V rail is within spec. The internal charge pump will generate the RS-232 bus voltages from 5V without issue.
