cmos dual 4-stage static shift register
DESCRIPTION
UCD4015 consists of two identical,independent,4-stage
serial-input/parallel-output registers. Each register has
independent CLOCK and RESET input as well as a single serial
DATA input. ”Q” outputs are available from each of the four
stages on both registers. All registers stages are D-type,
master-slave flip-flops. The logic level present at the DATA input
is transferred into the first register stage and shifted over one
stage at each positive-going clock transition. Resetting of all
stages is accomplished by a high level on the reset line. Register
expansion to 8 stages using one UCD4015 package or to more
than 8 stages using additional UCD4015’s is possible.
FEATURES
* 12MHz (typ.) clock rate at 10V
* Maximum input current of 1μA at 18V
* Fully static operation
* 8 master-slave flip-flops plus input and output buffering |
