| Standard ICs Quad 2-input NAND Schmitt trigger BU4093B / BU4093BF / BU4093BFV The BU4093B, BU4093BF, and BU4093BFV are 4-circuit, 2-input NAND gates whose input pins all have a Schmitt trigger function. As the circuit threshold voltages are different when the input waveform rises and when it falls (VIH, VIL), they can be used for line receivers, waveform rectification, multivibrators, and other purposes in addition to the customary usage as a NAND gate. They may be used in place of the BU4011B which uses the same pin connection. *Features dissipation. 1) Low power 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 A1 1 14 VDD 13 A4 12 B4 11 O4 10 O3 9 B1 2 O1 3 O2 4 B2 5 A2 6 B3 VSS 7 8 A3 *Truth table INPUT A L L H H B L H L H OUTPUT H H H L 1 Standard ICs BU4093B / BU4093BF / BU4093BFV *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 *Electrical characteristics otherwise noted, VSS = 0V, Ta = 25C) DC characteristics (unless Parameter Symbol Min. 3.5 Input high level voltage VIH 7.0 11.0 -- Input low level voltage VIL -- -- Input high level current Input low level current IIH IIL -- -- 4.95 Output high level voltage VOH 9.95 14.95 -- Output low level voltage VOL -- -- - 0.44 Output high level current IOH - 1.1 - 3.0 0.44 Output low level current IOL 1.1 3.0 -- Static current dissipation IDD -- -- 0.17 Hysteresis voltage VH 0.25 0.33 Typ. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Max. -- -- -- 1.5 3.0 4.0 0.3 - 0.3 -- -- -- 0.05 0.05 0.05 -- -- -- -- -- -- 1 2 4 0.39 0.60 0.90 V A mA mA V V A A V V Unit VDD (V) 5 10 15 5 10 15 15 15 5 10 15 5 10 15 5 10 15 5 10 15 5 10 15 5 10 15 -- Fig.3 VI = VDD or GND Fig.1 VOH = 4.6V VOH = 9.5V VOH = 13.5V VOL = 0.4V VOL = 0.5V VOL = 1.5V Fig.1 Fig.1 IO = 0mA Fig.1 IO = 0mA Fig.1 VIH = 15V VIL = 0V Fig.1 Fig.1 -- Fig.1 -- Fig.1 Conditions Measurement circuit 2 Standard ICs BU4093B / BU4093BF / BU4093BFV Switching characteristics (unless otherwise noted, VSS = 0V, Ta = 25C, CL = 50pF) Parameter Symbol Min. -- Output rise time tTLH -- -- -- Output fall time tTHL -- -- Propagation delay time, "L" to "H" -- tPLH -- -- -- Propagation delay time, "H" to "L" Input capacitance CIN tPHL -- -- -- Typ. 100 50 40 100 50 40 125 50 40 125 50 40 5 Max. -- -- -- -- -- -- -- -- -- -- -- -- -- pF ns ns ns ns Unit.
