54LS368A DM54LS368A DM74LS368A Hex TRI-STATE Inverting Buffers
General Description
This device contains six independent gates each of which performs an inverting buffer function The outputs have the TRI-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
