Overview
DM74LS125A Quad 3-STATE Buffer August 1986 Revised March 2000 DM74LS125A Quad 3-STATE Buffer General Description This device contains four independent gates each of which performs a non-inverting buffer function.
The outputs have the 3-STATE feature.
When enabled, the outputs exhibit the low impedance characteristics of a standard LS output with additional drive capability to permit the driving of bus lines without external resistors.
When disabled, both the output transistors are turned off presenting a high-impedance state to the bus line.
Thus the output will act neither as a significant load nor as a driver.
To minimize the possibility that two outputs will attempt to take a common bus to opposite logic levels, the disable time is shorter than the enable time of the outputs.
