MAX3232ECDR is a Texas Instruments dual RS-232 transceiver in SOIC-16, tape and reel — 3 V to 5.5 V supply, 2 drivers / 2 receivers at 250 kbps, ±15 kV IEC ESD protection on the bus pins, 300 µA typical operating current, 4 external 0.1 µF capacitors, accepts 5 V logic inputs while running at 3.3 V, rated 0 °C to +70 °C. The 3 V operation with 5 V-tolerant inputs is the selection point: it runs straight from a 3.3 V MCU rail in mixed-voltage designs with no level translation, while the charge pump still generates true RS-232 levels from a single supply. Selection advice: this exact code is TI second-source MAX3232E series — the TI suffix system applies (D = SOIC-16, R = reel 2,500), not the Maxim/ADI coding; the MAX3232ECD is the tube version, MAX3232ECDBR the SSOP reel, MAX3232ECPWR the TSSOP reel, and MAX3232EIDR the −40 °C to +85 °C industrial version. TI lists this code Active and recommends the MAX3232E for new designs; DigiKey also lists it as Active. Evidence: the TI MAX3232E datasheet SLLS664 packaging addendum confirms the ordering code, 250 kbps, ±15 kV ESD, SOIC-16 reel and Active status. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
MAX3232ECDR is a RS-232 transceiver from Texas Instruments, orderable in the SOIC-16 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.
When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. MAX3232ECDR names the SOIC-16 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
The package (SOIC-16) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Add MAX3232ECDR to your RFQ with the complete ordering code, the manufacturer (Texas Instruments), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
