54125 DM54125 DM74125 Quad TRI-STATE Buffers June 1989 54125 DM54125 DM74125 Quad TRI-STATE Buffers General Description This device contains four independent gates each of which performs a non-inverting buffer function The outputs 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...
