100323

Low Power Hex Bus Driver

General Description

The 100323 is a monolithic device containing six bus driv-

ers capable of driving terminated lines with terminations as

low as 25

Ω. To reduce crosstalk, each output has its own

respective ground connection. Transition times were

designed to be longer than on other F100K devices. The

driver itself performs the positive logic AND of a data input

Enabling of data is possible in multiples of two, i.e., 2, 4 or

all 6 paths. All inputs have 50 k

Ω pull-down resistors.

The output voltage LOW level is designed to be more neg-

ative than normal ECL outputs (cut off state). This allows

an emitter-follower output transistor to turn OFF when the

termination supply is

−2.0V and thus present a high imped-

ance to the data bus.
