9-Bit Shift Register
HIGH-PER.ORMANCE PRODUCTS Description
The SK10E/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. 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. Input data is accepted by the registers at set-up time before the posiitive going edge of CLK1 or CLK2. Shifting is also accomplished on the positive clock edge. A HIGH on the Master Reset pin (MR) asynchronously resets all the registers to zero.

NOTES: 1. Datums -L-, -M-, and -N- determined where top of lead shoulder exits plastic body at mold parting line. 2. DIM G1, true position to be measured at Datum -T-, Seating Plane. 3. DIM R and U do not include mold flash. Allowable mold flash is 0.010 (0.250) per side. 4. Dimensioning and tolerancing per ANSI Y14.5M, 1982. 5. Controlling Dimension: Inch. 6. The package top may be smaller than the package bottom by up to 0.012 (0.300). Dimensions R and U are determined at the outermost extremes of the plastic body exclusive of mold flash, tie bar burrs, gate burrs and interlead flash, but including any mismatch between the top and bottom of the plastic body. 7. Dimension H does not include Dambar protrusion or intrusion. The Dambar protrusion(s) shall not cause the H dimension to be greater than 0.037 (0.940). The Dambar intrusion(s) shall not cause the H dimension to be smaller than 0.025 (0.635).
