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 signifi-
cant 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
