The AD236JR is an RS-232 transceiver from Analog Devices, configured as a full-duplex interface with four drivers and three receivers.
Package and footprint — what the 24-SOIC means for your board
For a clean RS-232 layout, keep the charge-pump capacitors and the RS-232 connector close to the device to minimise trace inductance on the high-voltage rails. The package is listed as Bulk delivery — verify reel or tube quantity with your distributor when ordering production volumes.
Lifecycle and compliance — active but RoHS non-compliant
If your BOM requires lead-free assembly or RoHS-10 conformity, this device will not meet that requirement without an exemption. For lead-free builds, evaluate the ADM238LJRZ-REEL (same 4-driver/3-receiver count, full duplex, 120 kbps data rate, 650 mV hysteresis, also 0°C to 70°C) as a potential alternative.
