1 / 5 page © Semiconductor Components Industries, LLC, 2014 July, 2014 − Rev. 9 1 Publication Order Number: MC14517B/D MC14517B Dual 64-Bit Static Shift Register The MC14517B dual 64−bit static shift register consists of two identical, independent, 64−bit registers. Each register has separate clock and write enable inputs, as well as outputs at bits 16, 32, 48, and 64. Data at the data input is entered by clocking, regardless of the state of the write enable input. An output is disabled (open circuited) when the write enable input is high. During this time, data appearing at the data input as well as the 16−bit, 32−bit, and 48−bit taps may be entered into the device by application of a clock pulse. This feature permits the register to be loaded with 64 bits in 16 clock periods, and also permits bus logic to be used. This device is useful in time delay circuits, temporary memory storage circuits, and other serial shift register applications. Features • Diode Protection on All Inputs • Fully Static Operation • Output Transitions Occur on the Rising Edge of the Clock Pulse • Exceedingly Slow Input Transition Rates May Be Applied to the Clock Input • 3−State Output at 64th−Bit Allows Use in Bus Logic Applications • Shift Registers of any Length may be Fully Loaded with 16 Clock Pulses • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low−Power TTL Loads or One Low−Power Schottky TTL Load Over the Rated Temperature Range • NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable • This Device is Pb−Free and is RoHS Compliant MAXIMUM RATINGS (Voltages Referenced to VSS) Parameter Symbol Value Unit DC Supply Voltage Range VDD − 0.5 to +18.0 V Input or Output Voltage Range (DC or Transient) Vin, Vout −0.5 to VDD + 0.5 V Input or Output Current (DC or Transient) per Pin Iin, Iout ±10 mA Power Dissipation per Package (Note 1) PD 500 mW Operating Temperature Range TA − 55 to +125 °C Storage Temperature Range Tstg − 65 to +150 °C Lead Temperature (8−Second Soldering) TL 260 °C Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. Temperature Derating: Plastic “D/DW” Package: –7.0 mW/ _C From 65_C to 125 _C This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.
