Description for device types 03 and 04
These flip-flops are based on the master slave principle and each has AND gate inputs for entry into
the master section which are controlled by the clock pulse. The clock pulse also regulates the state of
the coupling transistors which connect the master and slave sections. The sequence of operation as
controlled by the clock pulse is as follows:
1.
Isolate slave from master.
2.
Enter information from AND gate inputs to master.
3.
Disable AND gate inputs.
4.
Transfer information from master to slave.
