Housed in a 20-TSSOP (4.40 mm width, 0.65 mm pitch), the surface-mount package keeps the footprint compact — about 6.5 mm × 6.4 mm — fitting into space-constrained designs alongside the MCU or SoC. The 20-TSSOP is a common logic-package footprint; the PCB land pattern matches the JEDEC MO-153 standard, so the layout is reusable across multiple transceiver or level-shifter variants in the same family.","metaTitle":"MAX3223EUP+ RS-232 Transceiver, 2/2, 120 kbps, 20-TSSOP","metaDescription":"Maxim Integrated MAX3223EUP+ RS-232 transceiver, full duplex 2/2 drivers/receivers, 120 kbps, 3V to 5.5V supply, 20-TSSOP.
