Product details

Through-hole DIP — repair and prototype staple

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. 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.

Frequently asked questions

Is SN75188N obsolete or still active?

The SN75188N is Active in production and ROHS3 compliant. There is no end-of-life notice or last-time-buy window in effect.

What is the difference between SN75188N and SN75189N?

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.
