1. General description
The HEF4517B consists of two identical, independent 64-bit static shift registers. Each
register has separate clock (nCP), data input (nD), parallel input-enable/output-enable
(nPE/OE) and four 3-state outputs of the 16th, 32nd, 48th, and 64th bit positions (nQ16 to
nQ64). Data at the nD input is entered into the first bit on the LOW-to-HIGH transition of
the clock, regardless of the state of nPE/OE.
When nPE/OE is LOW, the outputs are enabled and it is in the 64-bit serial mode.
When nPE/OE is HIGH, the outputs are disabled (high-impedance OFF-state), the 64-bit
shift register is divided into four 16-bit shift registers with nD, nQ16, nQ32 and nQ48 as
data inputs of the 1st, 17th, 33rd, and 49th bit respectively. Schmitt-trigger action in the
clock input makes the circuit highly tolerant of slower clock rise and fall times.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input.
