100316 Low Power Quad Differential Line Driver with Cut-Off
May 1991 Revised November 1999
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 50 transmission line (25 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.

Absolute Maximum Ratings(Note 1)

Recommended Operating Conditions
Case Temperature (TC) Commercial Industrial Supply Voltage (VEE) 0C to +85C -40C to +85C -5.7V to -4.2V
Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: ESD testing conforms to MIL-STD-883, Method 3015.

Note 3: The specified limits represent the "worst case" value for the parameter. Since these values normally occur at the temperature extremes, additional noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are chosen to guarantee operation under "worst case" conditions.
