HEF4517B Dual 64-bit static shift register Rev. 7 11 November 2011 Product data sheet 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 power supply range of 3 V to 15 V referenced to V DD SS (usually ground). Unused inputs must be connected to V , V , or another input. DD SS 2. Features and benefits Tolerant of slow clock rise and fall times Fully static operation 5 V, 10 V, and 15 V parametric ratings Standardized symmetrical output characteristics Specified from 40 C to +85 C Complies with JEDEC standard JESD 13-B 3.
