The AV-144 series accepts a TTL level input and provides a fixed level output. +10 Volt, +20 Volt and +30 Volt models are available. Units with a "1 or "3 suffix feature extremely fast rise and fall times and require a 50 Ohm load. Models AV-144B1-PS and AV-144C1-PS provide outputs of +20 and +30 Volts with rise times of 2.5 and 10 ns, respectively.
