The other resistor is a non-critical open collector pull-up (fOUT to +VCC). The VFC320 is available in two performance levels. The operating temperature of the VFC320 ranges from -25 ° C to +85 ° C
The MIC4467/8/9 family of four output CMOS buffer/drivers is an expansion from the earlier singleand dual-output drivers, to which they are functionally closely related.

Placing four high-power drivers in a single package also improves system reliability and reduces total system cost. In some applications, one of these drivers can replace not only two packages of single-input drivers, but some of the associated logic as well
