100323
Low Power Hex Bus Driver
General Description
The 100323 is a monolithic device containing six bus drivers
capable of driving terminated lines with terminations as low
as 25Ω. To reduce crosstalk, each output has its own re-
spective 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 (D1–D6) and
the OR of two select inputs (E and either DE1, DE2, or DE3).
Enabling of data is possible in multiples of two, i.e., 2, 4 or all
6 paths. All inputs have 50 kΩ pull-down resistors.
The output voltage LOW level is designed to be more nega-
tive than normal ECL outputs (cut off state). This allows an
emitter-follower output transistor to turn off when the termi-
nation supply is −2.0V and thus present a high impedance to
the data bus.

Note 7: The specified limits represent the “worst case” value for the parameter. Since these “worst case” values normally occur at the temperature extremes, ad-
ditional noise immunity and guard banding can be achieved by decreasing the allowable system operating ranges.
Note 8: Conditions for testing shown in the tables are chosen to guarantee operation under “worst case” conditions.
