Low Power Hex Bus Driver
100323 Low Power Hex Bus Driver July 1988 Revised August 2000 100323 Low Power Hex Bus Driver General Description Features The 100323 is a monolithic device containing six bus driv-50% power reduction of the 100123 ers capable of driving terminated lines with terminations as2000V ESD protection low as 25Ω. To reduce crosstalk, each output has its own −4.2V to −5.7V operating range respective ground connection. Transition times were Drives 25Ω load designed to be longer than on other F100K devices. The driver itself performs the positive logic AND of a data input (D –D ) and the OR of two select inputs (E and either DE , 1 6 1 DE , or DE ). 2 3 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 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.
