STMicroelectronics HCC4031B

The HCC4031B (extended temperature range) and HCF4031B (intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line plastic or ceramic package. The HCC/HCF4031B is a static shift register that contains 64 D-type, master-slave flip-flop stages and one stage which is a D-type master flip-flop only (referred to as a 1/2 stage). The logic level present at the DATA input is transferred into the first stage and shifted one stage at each positive-going clock transition.

DESCRIPTION

Maximum clock frequencies up to 16 Megahertz (typical) can be obtained. Because fully static operation is allowed, information can be permanently stored with the clock line in either the low or high state. The HCC/HCF4031B has a MODE CONTROL input that, when in the high state, allows operation in the recirculating mode. The MODE CONTROL input can also be used to select between two separate data sources. Register packages can be cascaded and the clock lines driven directly for high-speed operation. Alternatively, a delayed clock output(CLD) is provided that enables cascading regJune 1989 1/12 HCC/HCF4031B ister packages while allowing reduced clock drive fan-out and transition-time requirements. A third cascading option makes use of the Q’ output from the 1/2 stage, which is available on the next negative-going transition of the clock after the Q output occurs.
