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 (Dn, Dn) do not

have input pull-down resistors. An internal reference supply

(VBB) is available for single-ended operation.
