SY89311U

In Production

The SY89311U is a precision, high-speed 1:2 differential fanout buffer. Having within-device skews and output transition times significantly improved over the EL11V, the SY89311U is ideally suited for those applications which require the ultimate in AC performance in a small package.The differential inputs of the SY89311U employ clamping circuitry to maintain stability under open input conditions. If the inputs are left open, the Q outputs will be LOW.The differential inputs can accept 10/100K ECL/PECL signals (external termination required) and the outputs are 100K ECL/PECL compatible.....
