HEF4517BT集成电路（IC）的移位寄存器规格书PDF中文资料

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.
