1 / 4 page 1 Standard ICs Dual 4-bit static shift register BU4015B / BU4015BF The BU4015B and BU4015BF are 4-stage static shift registers, each consisting of two circuits. The D flip-flops for each stage share a common reset input, enabling external asynchronous reset at any point. Also, the flip-flops at each stage are triggered by the rising edge of the clock input. “H” level reset input resets the contents of all stages to “L”, regardless of the clock and data input, and sets data out- puts Q0 to Q3 to “L”. •Features 1) Low power dissipation. 2) Wide range of operating power supply voltages. 3) High input impedance. 4) High fan-out. 5) Direct drive of 2 L-TTL inputs and 1 LS-TTL input. •Block diagram 2 Q3B Q1A Q0A DA Q2B 3 4 5 6 RESET A 7 8 15 14 13 12 11 10 9 VSS 1 CLOCK B DB VDD Q0B Q1B Q2B Q3A RESET B CLOCK A 16 Q3 Q2 Q1 CL R D Q0 CL R D Q0 Q1 Q2 Q3 •Logic circuit diagram D Q0 Q1 Q2 Q3 CLOCK RESET DQ CL Q R DQ CL Q R DQ CL Q R DQ CL Q R •Truth table CLOCK D RESET Q0 Q1 Q2 Q3 LL L Q0 Q1 Q2 HL H Q0 Q1 Q2 X L No Change XX H L L L L X : Irrelevant |
