The 3-state outputs can be disabled by applying a HIGH TTL logic level on the mon OE input. The SY10H350 is designed to be used primarily in systems incorporating both ECL and TTL logic operating off a mon power supply. The separate VCC power pins are not connected internally and thus isolate the noisy TTL VCC runs from the relatively quiet ECL VCC runs on the printed circuit board. The differential inputs allow the H350 to be used as an inverting or noninverting translator, or a differential line receiver. The H350 can also drive CMOS with the addition of a pullup resistor.
