... MIC4467/4468/4469 General Description The MIC4467/8/9 family of 4-output CMOS buffer/drivers is an expansion from the earlier single- and dual-output drivers, to which they are functionally closely related. Because pack- age pin count permitted it, each driver has been equipped with a 2-input logic gate for added flexibility. Placing four high- power drivers in a single package also improves system reliability and reduces total system cost ...
