RS-232 port on a 3 V rail
The ICL3207ECAZ-T: Rated at 250 kbps, it handles standard UART traffic at common baud rates without pushing the edge of the part's timing budget. The 300 mV receiver hysteresis filters out noise on longer cable runs, reducing false start-bit detection in electrically noisy panels.
Channel count and supply compatibility
With five drivers and three receivers, this transceiver suits equipment that needs multiple RS-232 ports on a single IC — for example, a terminal server or multi-port industrial controller.
