Rated for a 250kbps data rate, it covers the common 115.2kbps and 230.4kbps UART speeds with margin. This is a 5V-only part — the supply range is 4.5V to 5.5V — so it's a direct drop into a legacy 5V logic rail. The base part number MAX232 is a decades-old industry standard, so the die and package are mature, well-characterised, and supported by multiple foundry sources within TI. This reduces the risk of a sudden supply disruption compared to a newer, single-sourced interface IC. ## Pin-compatible alternatives within the family The MAX232EID is part of a broad family. The MAX232AID is a direct pin-compatible upgrade that doubles the data rate to 1Mbps while keeping the same 5V supply and 16-SOIC footprint. If your design needs higher throughput — say, for a faster firmware download or a multi-drop polled network — the 'A' variant swaps in without a board spin. The MAX232EID is a current-production, widely stocked part.","metaTitle":"MAX232EID RS-232 Transceiver, 250kbps, 16-SOIC","metaDescription":"MAX232EID is an active RS-232 transceiver IC from TI.
