Dual 64-bit static shift register HEF4517B
LSI
DESCRIPTIONThe HEF4517B consists of two identical, independent
64-bit static shift registers. Each register has separate
clock (CP), data input (D), parallel
input-enable/output-enable (PE/EO) and four 3-state
outputs of the 16th, 32nd, 48th and 64th bit positions
(O16 to O64). Data at the D input is entered into the first bit
on the LOW to HIGH transition of the clock, regardless of
the state of PE/EO.
When PE/EO is LOW the outputs are enabled and the
device is in the 64-bit serial mode.
When PE/EO is HIGH the outputs are disabled (high
impedance OFF-state), the 64-bit shift register is divided
into four 16-bit shift registers with D, O16, O32 and O48as
data inputs of the 1st, 17th, 33rd, and 49th bit respectively.
Schmitt-trigger action in the clock input makes the circuit
highly tolerant to slower clock rise and fall times.
