| Standard ICs Hex Schmitt trigger BU4584B / BU4584BF / BU4584BFV The BU4584B, BU4584BF, and BU4584BFV are inverter-type Schmitt trigger circuits, with six circuits mounted on a single chip. These are ideal when enhanced noise immunity is required, and when wave form rectification circuits with slow rise or fall input times are involved. *Features dissipation. 1) Low power 2) Wide range of operating power supply voltage. 3) High input impedance. 4) High fan-out. 5) Direct drive of 2 L-TTL inputs and LS-TTL input. *Block diagram I1 1 14 VDD 13 I6 12 O6 11 I5 10 O5 9 O1 2 I2 3 O2 4 I3 5 O3 6 I4 VSS 7 8 O4 *Absolute maximum ratings (VSS = 0v, Ta = 25C) Parameter Power supply voltage Power dissipation Operating temperature Storage temperature Input voltage Symbol VDD Pd Topr Tstg VIN Limits - 0.3 ~ + 18 1000 (DIP), 450 (SOP), 350 (SSOP) - 40 ~ + 85 - 55 ~ + 150 - 0.3 ~ VDD + 0.3 Unit V mW C C V 1 Standard ICs BU4584B / BU4584BF / BU4584BFV *Electrical characteristics otherwise noted, VSS = 0V, Ta = 25C) DC characteristics (unless Parameter Symbol Min. 3.5 7.0 11.0 -- -- -- -- -- 4.95 9.95 14.95 -- -- -- - 0.44 - 1.1 - 3.0 0.44 1.1 3.0 -- -- -- 0.15 0.25 0.40 Typ. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Max. -- -- -- 1.5 3.0 4.0 0.3 - 0.3 -- -- -- 0.05 0.05 0.05 -- -- -- -- -- -- 1 2 4 0.6 1.0 1.5 Unit Input high level voltage VIH V VDD (V) 5 10 15 5 10 15 15 15 5 10 15 5 10 15 5 10 15 5 10 15 5 10 5 5 10 15 Conditions Measurement circuit -- Input low level voltage Input high level current Input low level current Output high level voltage VIL IIH IIL VOH V A A V -- VIH = 15V VIL = 0V IO = 0mA Fig.1 Output low level voltage VOL V IO = 0mA VOH = 4.6V VOH = 9.5V VOH = 13.5V VOL = 0.4V VOL = 0.5V VOL = 1.5V -- -- Output high level current IOH mA Output low level current IOL mA Static current consumption IDD A Hysteresis voltage VH V -- Fig.1 Switching characteristics (unless otherwise noted, Ta = 25C, VSS = 0 V, CL =50pF) Parameter Symbol Min. -- -- -- -- -- -- -- -- -- -- -- -- Typ. 100 50 40 100 50 40 125 60 50 125 60 50 Max. -- -- -- -- -- -- -- -- -- -- -- -- Unit VDD (V) 5 10 15 5 10 15 5 10 15 5 10 15 Conditions Measurement circuit Fig.2 Output rise time tTLH ns -- Output fall time tTHL ns -- Fig.2 Propagation delay time, "L" to "H" Propagation delay time, "H" to "L" tPLH ns -- Fig.2 tPHL ns -- Fig.2 2 Standard ICs BU4584B / BU4584BF / BU4584BFV *Measurememt circuits VDD VDD 20ns 20ns Input A V GND P.
