DM54LS125A

This DM54LS125A device contains four independent gates each of which performs a non-inverting buffer function. The outputsof DM54LS125A have the TRI-STATE feature. When enabled, the outputs of DM54LS125A 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 outputsof DM54LS125A.
