The 100323 is a monolithic device containing six bus drivers capable of driving terminated lines with terminations as low as 25 Ohm. 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 (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 k Ohm pull-down resistors.

The output voltage LOW level is designed to be more negative 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 impedance to the data bus.
