This 6/10 driver/receiver count is unusually high for a single transceiver IC — most RS232 parts offer 2/2 or 5/3 — making this part suited for applications requiring many serial ports or multi-drop RS232 buses without external multiplexing. Data rate is specified at 120 Kbps, which covers standard RS232 communication up to 115.2 Kbps with margin. ## Supply and temperature range The PLCC-44 package (J-Lead, 16.59 x 16.59 mm body) is a surface-mount form factor with leads on all four sides. The J-lead geometry provides a smaller footprint than a DIP while still allowing visual inspection of solder joints — a practical advantage for rework and prototype builds compared to fine-pitch QFP or BGA packages.","metaTitle":"MAX249CQH+D RS232 Transceiver, 6/10 Drivers, 120Kbps","metaDescription":"MAX249CQH+D Analog Devices RS232 transceiver, full duplex, 6 drivers / 10 receivers, 120Kbps data rate, 44-PLCC package.
