100319 Low Power Hex Line Driver with Cut-Off
May 1991 Revised November 1999
100319 Low Power Hex Line Driver with Cut-Off
General Description
The 100319 is a Hex Line Driver with output cut-off capability. The 100319 has single ended ECL inputs and differential ECL outputs, designed to drive a differential, doubly terminated 50 transmission line (25 equivalent impedance) in an ECL backplane. A LOW on the Output Enable (OE) will set both the true and complementary outputs, to a high impedance or cut-off state. The cut-off state is designed to be more negative than a normal ECL LOW state.
Features
s Differential outputs s Output cut-off capability s Drives a 25 ECL load s 2000V ESD protection s Voltage compensated range = -4.2V to -5.7V s Available to industrial grade temperature range

Absolute Maximum Ratings(Note 1)
Storage Temperature (TSTG) Maximum Junction Temperature (TJ) Pin Potential to Ground Pin (VEE) Input Voltage (DC) Output Current (DC Output HIGH) ESD (Note 2) -65C to +150C +150C -7.0V to +0.5V VEE to +0.5V -100 mA 2000V
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.
