The 14-DIP (0.300" width) through-hole package is breadboard-friendly and easy to hand-solder. For MRO teams repairing legacy PLCs, CNC controllers, or point-of-sale terminals, the DIP form factor means no adapter board needed.
If a line-down situation hits, the through-hole DIP and mature process mean surplus stock is also widely available on the spot market.
The SN75188N is Active in production and ROHS3 compliant. There is no end-of-life notice or last-time-buy window in effect.
The SN75188N is a quad RS-232 driver (4 drivers, 0 receivers). The SN75189N is a quad RS-232 receiver (0 drivers, 4 receivers). They are complementary parts for the same RS-232 interface — one drives the line, the other receives.
