DM54367 Hex TRI-STATE

Buffers

General Description

This device contains six 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 to permit the driving of bus

lines without external resistors When disabled both the

output transistors are turned off presenting a high-imped-

ance state to the bus line Thus the output will act neither as

a signficant load nor as a driver To minimize the possibility

that two outputs will attempt to take a common bus to oppo-

site logic levels the disable time is shorter than the enable

time of the outputs
