i want circuit designe of security monitoring system using 74HC151 connected with 74HC138, BCD 7490

thanx for all

 

what kind of security device are you looking for...

These specific parts are good for part of the circuit, but need sensors, monitors, and power.

Is this just for a homework project, or for an actual design.
