The M C14500B I ndustrial C ontrol Unit (ICU) i s a single–bit C MOS processor. The ICU is designed for use in systems requiring decisions based on successive single–bit information. An external ROM stores the control program. With a program counter (and output latches and input multiplexers, if required) the ICU in a system forms a stored–program controller that replaces combinatorial logic. Applications include relay logic processing, serial data manipulation and control. The ICU also may control an MPU or be controlled by an MPU.

#Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high–impedance circuit. For proper operation, Vin and V

out

should be constrained

to the range VSS v (Vin or V

out

) v VDD.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either V

SS

or VDD). Unused outputs must be left open.
