HEF4021BP - Brand New PHILIPS Shifting Register
- One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
DESCRIPTION
The HEF4021B is an 8-bit static shift register (parallel-to-serial converter)
with a synchronous serial data input (DS), a clock input (CP), an asynchronous
active HIGH parallel load input (PL), eight asynchronous parallel data inputs
(P0 to P7) and buffered parallel outputs from the last three stages (05 to
O7).
Each register stage is a D-type master-slave flip-flop with a set direct/clear
direct input. Information on P0 to P7 is asynchronously loaded into the
register while PL is HIGH, independent of CP and DS. When PL is LOW, data on
DS is shifted into the first register position and all the data in the
register is shifted one position to the right on the LOW to HIGH transition of
CP. Schmitt-trigger action in the clock input makes the circuit highly
tolerant to slower clock rise and fall times.
