MC10EP142, MC100EP142
3.3 V / 5 V ECL 9-Bit Shift Register
The MC10EP/100EP142 is a 9−bit shift register, designed with byte-parity applications in mind. The MC10/100EP142 is capable of performing serial/parallel data into serial/parallel out and shifting in only one direction. The nine inputs D0 − D8 accept parallel input data, while S−IN accepts serial input data. The QT0:87 outputs do not need to be terminated for the shift operation to function. To minimize power, any Q output not used should be left unterminated.
The SEL (Select) input pin is used to switch between the two modes of operation − SHIFT and LOAD. The shift direction is from Bit 0 to Bit 8.
