The Analog Devices LT1138ACG#PBF is an RS232 full-duplex transceiver with five drivers and three receivers in a 28-SSOP package.
Rated at 250 KBd, the LT1138ACG#PBF covers the standard RS232 range with headroom for 250 kbps links. The 400 mV receiver hysteresis helps reject noise on longer runs.
That means no last-time-buy scramble and no forced requalification for existing designs.
The LT1138ACG#PBF is rated for 250 KBd, which covers standard RS232 rates up to 115.2 kbps with margin for 250 kbps links.
The ADM202JRWZ-REEL is a functional RS232 transceiver but offers only 2 drivers and 2 receivers versus the LT1138ACG#PBF's 5/3 configuration. For a closer channel count match, the ADM241LJRZ provides 4 drivers and 5 receivers, though at 120 Kbps data rate. Neither is pin-compatible — verify footprint before substituting.
