CD4043BDR TI Latches

The CD4043B is a quad NOR R-S latch with 3-state outputs, operating from 3 V to 18 V supply. It features four independent latches with complementary outputs (Q and Q̄), each with a set (S) and reset (R) input. The device uses NOR logic, meaning the latch is set when S is high and R is low, and reset when R is high and S is low. 3-state outputs allow bus sharing. Packaged in a 16-pin SOIC, the CD4043B is ideal for high-voltage CMOS systems requiring quad set-reset latches with 3-state outputs. Applications include I/O port expansion, data storage, control registers, and bus-interface storage in industrial controls, automotive electronics, and consumer systems.
