ABSTRACT:
A hand-shake type control circuit for controlling a data transfer circuit according to the status of a data transfer request signal. The data transfer request signal is initially received at a NAND gate and is also directly coupled to the reset input of are set flip-flop. The output of the NAND gate is used as a first control signal to set the flip-flop and to cause another circuit to activate data transfer. The flip-flop output is a second control signal which is reset only when the transfer request signal changes from an active to an inactive status. The second control signal is coupled to an input of the NAND gate and inactivates the first control signal. Thus, data transfer cannot recur until after the data transfer request signal changes to an inactive status so that parasitic oscillations are eliminated. The flip-flop consists of two, two input NAND gates that are located out of the path of data transfer and that are easier to fabricate than the prior art D flip-flop.
