CD4517BMS dual 64-stage static shift
register consists of two independent registers
each having a clock, data, and write enable
input and outputs accessible at taps following
the 16th, 32rd, 48th, and 64th stages. These
taps also serve as input points allowing data
to be inputted at the 17th, 33rd, and 49th
stages when the write enable input is a logic
1 and the clock goes through a low-to-high
transition. The truth table indicates how the
clock and write enable inputs control the
opeation of the CD4517BMS. Inputs at the
intermediate taps allow entry of 64 bits into
the register with 16 clock pulses. The 3-state
outputs permit connection of this device to an
external bus.
The CD4517BMS is supplied in these 16 lead
