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 backp l ane . Th e 10 031 6 i s idea l fo r dr ivi ng

low noise, differe ntial E CL backp lanes. A LOW on the out-

put enable (OE) will set both the tru e and complementary

outputs into a high impedance or cut-off state, isolating

them from the ba ckplane. The cut-o ff state is designed to

be more negative than a normal ECL LOW state.

Unlike mo st 100K d evices, the data in puts (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

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 c ho-

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