The wide supply range (3V to 5.5V) means you can drop this into a 3.3V system without extra regulators, or run it straight off a 5V rail. The 300 mV receiver hysteresis gives clean logic transitions even on noisy cables. Not for a motor drive or an outdoor telecom cabinet. The MAX3232CDE4 is officially marked obsolete. TI no longer manufactures this specific suffix (the 'C' commercial grade in a tube). If you have a legacy design that uses it, you are looking at the surplus and broker channel. No last-time-buy window remains; this is strictly a replacement or bridge-buy scenario.","metaTitle":"MAX3232CDE4 RS-232 Transceiver, 250 kbps, 3V-5.5V, 16-SOIC","metaDescription":"MAX3232CDE4 is a full-duplex RS-232 transceiver with 2/2 drivers/receivers, 250 kbps data rate, 3V to 5.5V supply, 16-SOIC.
