TC4021BP

IC 4000/14000/40000 SERIES, 8Bit RIGHT PARALLEL IN SERIAL OUT SHIFT REGISTER, TRUE OUTPUT, PDIP16, 0.3INCH, 2.54MM PITCH, PLASTIC, DIP-16, Shift Register

TC4021B is 8 stage parallel in/serial out shift register, which can be used also for serial in/serial out operations. In the case of parallel operation, the data of PARALLEL IN is input to each F/F asynchronously with CLOCK and the output is obtained. In the case of serial operations, each F/F is triggered by rising edge of CLOCK. asynchronous parallel or synchronous serial input Switching of PARALLEL operation and SERIAL operation is achieved by P/ S CONTROL input. When P/ S CONTROL input is “H”, PARALLEL operation is designated and when it is “L”, SERIAL operation is designated.
