1 standard ics single inverter BU4SU69 the BU4SU69 is an ultra-compact ic with one circuit of the bufferless inverter, bu4069ub, built into the smp pack- age. the single-stage gate configuration enables a short propagation time. features 1) low current dissipation. 2) super-mini mold package designed for surface mounting. 3) wide range of operating power supply voltage. 4) direct drive of 2 l-ttl inputs and 1 ls-ttl input. block diagram 54 123 v dd y nc a v ss absolute maximum ratings (ta = 25?) parameter symbol limits unit power supply voltage v dd v ss ? 0.3 ~ v ss + 18 v power dissipation pd 170 mw input current i in 10 ma operating temperature topr ? 40 ~ + 85 c storage temperature tstg ? 55 ~ + 150 c input voltage v in v ss ? 0.3 ~ v dd + 0.3 v * 1 these values indicate the range limits of the voltage that can be applied to each pin without destroying it. operation is not guaranteed at these values. * 2 power dissipation is reduced by 1.7mw for each increase in ta of 1 c over 25 c. recommended operating conditions (ta = 25?, v ss = 0v) parameter symbol min. typ. max. unit power supply voltage v dd 3 16 v input voltage v in 0 v dd v
