TRANSLATOR DESCRIPTION FEATURES

в– The SY10H350 consists of 4 translators with differential
inputs and TTL outputs. The 3-state outputs can be
disabled by applying a HIGH TTL logic level on the
common OE input.
The SY10H350 is designed to be used primarily in
systems incorporating both ECL and TTL logic operating
off a common 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. Single 5V power supply
Propagation delay, 3.5ns typical
Fully compatible with MC10H350
