DM74LS126A Quad 3-STATE Buffer
August 1986
Revised March 2000
DM74LS126A
Quad 3-STATE Buffer
General Description
This device contains four independent gates each of which
performs a non-inverting buffer function. The outputs have
the 3-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-imped-
ance state to the bus line. Thus the output will act neither
as a significant load nor as a driver. To minimize the possi-
bility 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.
