Shared details from SKU000628

MAX238 RS-232 transceiver

These details belong to the SKU and are shared by its batches.

Maxim MAX238CWG RS-232 line-interface IC with four transmitters and four receivers. Converts TTL/CMOS serial signals to/from EIA/TIA-232E and V.28/V.24 levels. Integrated charge pump operates from a single nominal 5 V supply, with four external charge-pump capacitors required. Useful for legacy serial ports, equipment interfaces and diagnostics; serial protocol/UART control is provided by other circuitry. The label and visible chip identify MAX238CWG, without a + suffix; no lead-free suffix is inferred from newer catalog entries.
