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
