Clock and Voltage Requirements
Clocks requirements are relatively simple. As it was indicated in Figure 5 and Table 1, there
are only three input signals that require clocked inputs. They are CLK, the clock for the shift
register, START, the shift register start pulse, and RESET, the reset control gate. However, in
certain applications where the internal reset circuitry is unused, RESET can be tied to ground.
