DESCRIPTION
Precision Edge^®
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.
