100316 Low Power Quad Differential Line Driver with Cut-Off
100316
Low Power Quad Differential Line Driver with Cut-Off
General Description
The 100316 is a quad differential line driver with output cutoff capability. The outputs are designed to drive a doubly
terminated 50Ω transmission line (25Ω equivalent impe dance) in an ECL backplane. Th e 10 031 6 i s idea l fo r dr ivi ng
low noise, differential E CL backp lanes. A LOW on the ou tput enable (OE) will s et both the true an d complementary
outputs into a high impedance or cut-off state, isolating
them from the backpla ne. The cut-off state is designed to
be more negative than a normal ECL LOW state.
Unlike most 100K device s, the data inputs (D
n
, Dn) do not
have input pull-down resistors. An internal reference supply
(V
BB
) is available for single-ended operation.
