DM54125

DM54125 contains four independent gates each of which performs a non-inverting buffer function The outputs of DM54125 have the TRI-STATE feature. When enabled, the outputs exhibit the low impedance characteristics of a standard TTL output with additional drive capability at the high Logic level to permit the driving of bus lines without external pull-up 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 opp-osite logic levels the disable time is shorter than the enable time of the outputs of DM54125.
