100316
Low Power Quad Differential Line Driver with Cut-Off
General Description
The 100316 is a quad differential line driver with output cut-
off capability. The outputs are designed to drive a doubly
terminated 50Ω transmission line (25Ω equivalent imped-
ance) in an ECL backplane. The 100316 is ideal for driving
low noise, differential ECL backplanes. A LOW on the out-
put enable (OE) will set both the true and complementary
outputs into a high impedance or cut-off state, isolating
them from the backplane. The cut-off state is designed to
be more negative than a normal ECL LOW state.
Unlike most 100K devices, the data inputs (D
n
, D
n
) do not
have input pull-down resistors. An internal reference supply
(V
BB
) is available for single-ended operation.
