The 74HC86D, 7486D, HC86D are contain four independent 2-input exclusive-OR gates. They perform the Boolean function Y = A B or Y = AB + A(B) in positive logic. A common application is as a true/complement element.
The CD4040BM is ripple-carry binary counters. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transition of each input pulse, a high level on the RESET line resets the counter to its all zeros stat
The 2SC3679, 2SC-3679, 3679 is a 900V 5A 100W Silicon NPN Triple Diffused Planar High Voltage Switching Transistor TO-218 Package, Manufactured By SANKEN Semiconductor.
The CD4026B- and CD4033B-series types are supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
