General Description MIC4467/4468/4469 Power Logic CMOS Quad Drivers Bipolar/CMOS/DMOS Features The MIC4467/8/9 family of 4-output CMOS buffer/drivers is * Built using reliable, low power CMOS processes an expansion from the earlier single- and dual-output drivers, * Latchproof. Withstands 500mA Inductive Kickback to which they are functionally closely related. Because pack- 3 Input Logic Choices / age pin count permitted it, each driver has been equipped * Symmetrical Rise and Fall TIMES ......... ee eeeeeee 25ns with a 2-input logic gate for added flexibility.

The MIC446X series drivers are built using a BCD process. They will not latch under any conditions within their power and voltage ratings. They are not subject to damage when up to Micrel! 5V of noise spiking (either polarity) occurs on the ground line. They can accept up to half an amp of inductive kickback current (either polarity) into their outputs without damage or logic upset. Ordering Information Truth Table Part No. Package _ Temp.
