For MRO teams repairing legacy PLCs, CNC controllers, or point-of-sale terminals, the DIP form factor means no adapter board needed. The 0°C to 70°C commercial temperature grade limits it to indoor, conditioned environments — not for unheated enclosures or under-hood automotive use. ## Lifecycle and sourcing The SN75188N is listed as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window has been announced. If a line-down situation hits, the through-hole DIP and mature process mean surplus stock is also widely available on the spot market.","metaTitle":"SN75188N RS-232 Driver, 4/0, 14-DIP, Active","metaDescription":"SN75188N is a TI RS-232 line driver with 4 drivers, 0 receivers, ±7.5V to 15V supply, 14-DIP package.
