PIN-TO-PIN ALTERNATIVE
SIT3232E is a Chinese-manufactured pin-to-pin drop-in replacement for MAX3232 (Maxim / Analog Devices).
RS-232 cross-reference with wide supply range and 15 kV ESD protection.
SIT3232E — Alternative to MAX3232
SIT3232E from SIT {BRAND} is supplied by JTDZ Tech (Shenzhen Jingteng Electronics) as a cost-effective, short-lead-time alternative to the imported MAX3232 (Maxim / Analog Devices). Chinese-sourced semiconductors have moved well beyond "cheap substitute" status: the parts below are production-validated in industrial, automotive and consumer designs, and they remove both the allocation risk and the long lead times that come with imported.
