100319
Low Power Hex Line Driver with Cut-Off
General Description
The 100319 is a Hex Line Driver with output cut-off capabil-
ity. The 100319 has single ended ECL inputs and differen-
tial ECL outputs, designed to drive a differential, doubly
terminated 50Ω transmission line (25Ω equivalent imped-
ance) in an ECL backplane. A LOW on the Output Enable
(OE) will set both the true and complementary outputs, to a
high impedance or cut-off state. The cut-off state is
designed to be more negative than a normal ECL LOW
state.
