100341 100341 Low Power 8-Bit Shift Register Literature Number: SNOS130 100341 Low Power 8-Bit Shift Register General Description Features The 100341 contains eight edge-triggered, D-type flip-flops with individual inputs (Pn) and outputs (Qn) for parallel operation, and with serial inputs (Dn) and steering logic for bidirectional shifting. The flip-flops accept input data a setup time before the positive-going transition of the clock pulse and their outputs respond a propagation delay after this rising clock edge. The circuit operating mode is determined by the Select inputs S0 and S1, which are internally decoded to select either "parallel entry", "hold", "shift left" or "shift right" as described in the Truth Table. All inputs have 50 k pull-down resistors. n n n n n 35% power reduction of the 100141 2000V ESD protection Pin/function compatible with 100141 Voltage compensated operating range = -4.2V to -5.7V Standard Microcircuit Drawing (SMD) 5962-9459101 Logic Symbol Pin Names Description CP Clock Input S0, S1 Select Inputs D0, D7 Serial Inputs P0-P7 Parallel Inputs Q0-Q7 Data Outputs DS100315-1 (c) 1998 National Semiconductor Corporation DS100315 www.national.com 100341 Low Power 8-Bit Shift Register August 1998 Connection Diagrams 24-Pin DIP 24-Pin Quad Cerpak DS100315-3 DS100315-2 www.national.com 2 Logic Diagram DS100315-5 Truth Table Function Inputs Outputs D7 D0 S1 S0 CP Q7 Q6 Q5 Q4 Q3 Q2 Q1 Q0 Load Register X X L L N P7 P6 P5 P4 P3 P2 P1 P0 Shift Left X L L H N Q6 Q5 Q4 Q3 Q2 Q1 Q0 L Shift Left X H L H N Q6 Q5 Q4 Q3 Q2 Q1 Q0 H Shift Right L X H L N L Q7 Q6 Q5 Q4 Q3 Q2 Q1 Shift Right H X H L N H Q7 Q6 Q5 Q4 Q3 Q2 Q1 Hold X X H H X Hold X X X X H Hold X X X X L No Change H = HIGH Voltage Level L = LOW Voltage Level X = Don't Care N = LOW-to-HIGH Transition 3 www.national.com Absolute Maximum Ratings (Note 1) 2000V ESD (Note 2) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
