Revised November 1999 100319 Low Power Hex Line Driver with Cut-Off General Description Features 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. Differential outputs Output cut-off capability Drives a 25 ECL load 2000V ESD protection Voltage compensated range = -4.2V to -5.7V Available to industrial grade temperature range Ordering Code: Order Number Package Number Package Description 100319QC V28A 28-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.450 Square 100319QI V28A 28-Lead Plastic Lead Chip Carrier (PLCC), JEDEC MO-047, 0.450 Square Industrial Temperature Range (-40C to +85C) Devices also available in Tape and Reel.

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.
