BU4021BF-E2

Standard ICs 8-bit static shift register BU4021B / BU4021BF The BU4021B and BU4021BF are 8-bit static shift registers consisting of 8 register cells, each of which has parallel input. Control of the parallel / serial control input (P / S) enables serial input / serial output with clock synchronization, as well as parallel input / serial output conversions. •Absolute maximum ratings (V SS Parameter Power supply voltage = 0V, Ta = 25°C) Symbol Limits Unit 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 •Logic circuit diagram •Block diagram P8 P/S (9) Ds (11) CLOCK (10) P1 (7) P2 (6) P3 (5) P4 (4) P5 (13) P6 (14) P8 (1) P7 (15) Q6 Q8 D Q D Q D Q D Q D Q C C C C C D Q D Q Q C Q C Q C P4 (12) Q7 P7 Q6 P6 Q8 P5 P4 Q7 P3 DS 3 4 5 16 VDD 15 P7 14 P6 13 P5 12 Q7 P2 6 P2 CLOCK 11 DS P1 7 P1 P/S 10 CLOCK VSS 8 9 P/S (3) Q8 Truth table •Serial operation P8 2 D P3 (2) Q6 1 Parallel operation P/S Q6 Q7 Q8 (t = n + 6) (t = n + 7) (t = n + 8) t CLOCK DS n L L 0 ? ? n+1 H L 1 0 ? n+2 L L 0 1 0 n+3 H L 1 0 1 X L Q6 Q7 Q8 CLOCK DS P / S Dm Qm∗ X H L L X H H H X: Irrelevant ∗: Q6, Q7, and Q8 are external 1 Standard ICs BU4021B / BU4021BF characteristics •DCElectrical characteristics (unless otherwise noted, Ta = 25°C, V Parameter Input high level voltage 3.5 — — VIH 7.0 — — 11.0 — — 15 — — 1.5 5 — — 3.0 — — 4.0 — — Input high level current IIH Input low level current IIL Output low level voltage Output high level current Output low level current Static current dissipation 2 Min.
