BU4015BF-E2

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 outputs Q0 to Q3 to “L”. •1)Features Low power dissipation. 2) Wide range of operating power supply voltages. 3) High input impedance. •Block diagram 4) High fan-out. 5) Direct drive of 2 L-TTL inputs and 1 LS-TTL input. •Logic circuit diagram Q1 Q0 CLOCK B 1 16 VDD Q3B 2 15 DB Q2B 3 14 RESET B Q1A 4 13 Q0B Q0A 5 12 Q1B 11 Q2B D CL R D Q3 Q2 Q1 Q0 CLOCK D Q CLR Q D Q CLR Q Q2 D Q CLR Q Q3 D Q CLR Q RESET Q 0 Q1 Q2 Q3 RESET A 6 DA 7 10 Q3A VSS 8 9 CLOCK A CL R D •Truth table CLOCK X D RESET Q0 Q1 Q2 Q3 L H L L Q0 Q1 Q2 L H Q0 Q1 Q2 X L X H No Change L L L L X : Irrelevant 1 Standard ICs BU4015B / BU4015BF •Absolute maximum ratings (V SS = 0V, Ta = 25°C) Parameter Symbol Limits Power supply voltage VDD – 0.3 ~ + 18 V Power dissipation Pd 1000 (DIP), 500 (SOP) mW Operating temperature Topr – 40 ~ + 85 °C Storage temperature Tstg – 55 ~ + 150 °C – 0.3 ~ VDD + 0.3 V Input voltage VIN characteristics •DCElectrical characteristics (unless otherwise noted, Ta = 25°C, V Parameter Input high level voltage Input low level voltage = 0V) Symbol Min. 3.5 — — VIH 7.0 — — 11.0 — — 15 — — 1.5 5 — — 3.0 — — 4.0 VIL Typ.
