100319

Low Power Hex Line Driver with Cut-Off

General Description

The 100319 is a Hex Line Driver with output cut-off capabil-

ity. The 100319 has sing le ended ECL input s and differen-

tial ECL outputs, designed to drive a differential, doubly

terminated 50Ω transmission line (25Ω equivalent imped-

ance) in an ECL backpl ane. 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

■Differential outputs

■Output cut-off capability

■Drives a 25Ω ECL load

■2000V ESD protection

■Voltage compensated range = −4.2V to −5.7V

■Available to industrial grade temperature range

Ordering Code:

Devices also available in Tape and R eel. Speci fy by append ing the suffix let t er “X” to the o rdering c ode.

Absolute Maximum Ratings(Note 1) Recommended Operating

Conditions

Note 1: The “A bsolute Maximum Ratings” are thos e values bey ond which

the saf ety of the device cannot be gu aranteed. Th e device shou ld not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the absolute maximum rating.

The “R ecomm ended Ope rating Co ndition s” table will define the condit ions

for actu al device operation.

Note 2: ESD testing conforms to MIL-STD-883, Method 3015.

DC Electrical Characteristics (Note 3)

VEE = −4.2V to −5.7V, VCC = VCCA = GND, TC = 0°C to +85°C

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 an d gu ardband ing c an be achi eved by d ecre asin g the al l owable syste m operating ranges. Condit i ons fo r t estin g sho w n in the tables are cho-

sen to guarante e operation under “worst case” conditions.
