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 25
Ω. 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 (D
1–D6) and
the OR of two select inputs (E and either DE
1,DE2,orDE3).
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 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.
