If your board runs a 3.3V logic rail, you will need a separate 5V supply or a level-shifter ahead of the transceiver. The 120 kbps data rate covers standard UART speeds up to 115200 baud with margin; no need to hunt for a faster part if your application tops out there. ## Active lifecycle — no LTB worry For new designs or sustaining a legacy BOM, this part is a safe pick from a lifecycle standpoint.","metaTitle":"MAX232D RS-232 Transceiver, 120 kbps, 16-SOIC","metaDescription":"Texas Instruments MAX232D RS-232 transceiver, full duplex, 2/2 drivers/receivers, 120 kbps data rate, 4.5V to 5.5V supply, 16-SOIC.

Check your board footprint — if it was designed for a 16-pin SOIC, this part drops in."},{"question":"What is the data rate of MAX232D?","answer":"The MAX232D supports data rates up to 120 kbps.
