description

The 'S134 feature three-state outputs that, when enabl-
ed, have the low impedance characteristics of a TTL
output with additional drive capability at high logic
levels to permit driving heavily lcaded lines without ex-
ternal pull-up resistors. When disabled, both output
transistors are turned off presenting a high-impedance
state to the bus so the output will act neither as a signifi-
cant load nor as a driver. The ‘S134 outputs are diabled
when G is high.
