The MC10E/100E160 is a 12-bit parity generator/checker. The Q output is HIGH when an odd number of inputs are HIGH. A HIGH on the Enable input (EN) forces the Q output LOW. The E160 also features an output register. Multiplexers direct the register input, giving the option of holding present data by asserting HOLD LOW, or of shifting data in through the S-IN pin by asserting SHIFT HIGH. The output register itself is clocked by a positive edge on CLK1 or CLK2 (or both). A HIGH on the reset pin (R) overrides to force the Y output LOW.
