The T124 logic buffer provides a fast 1 to 4 fanout buffer/inverter for digital logic signals. Input features a switchable 50R or high-impedance termination, as well as a switchable 10MHz bandpass filter for use as a clock distribution amplifier. Outputs can be switched between a low-impedance or 50R source, and the output high voltage is switchable between 3.3V and 5V. The short-circuit protected outputs can be used for any digital logic distribution application.
