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 impedance) in an ECL backplane. The 100316 is ideal for driving low noise, differential ECL backplanes. A LOW on the output 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 (Dn, Dn) do not have input pull-down resistors. An internal reference supply (VBB) is available for single-ended operation.
