9ĆBit Shift Register
The MC10E/100E142 is a 9-bit shift register, designed with byte-parity applications in mind. The E142 performs serial/parallel in and serial/parallel out, shifting in one direction. The nine inputs D0 – D8 accept parallel input data, while S-IN accepts serial input data. The Qn outputs do not need to be terminated for the shift operation to function. To minimize noise and power, any Q output not used should be left unterminated.
• 700MHz Min. Shift Frequency • 9-Bit for Byte-Parity Applications • Asynchronous Master Reset • Dual Clocks • Extended 100E VEE Range of – 4.2V to – 5.46V • 75kΩ Input Pulldown Resistors
The SEL (Select) input pin is used to switch between the two modes of operation — SHIFT and LOAD.
