The SY10/100EP11U is a precision, high-speed 1:2
differential fanout buffer. Having within-device skews and
Wide temperature range: 40C to +85C
output transition times significantly improved over the
Available in 8-pin (3mm) MSOP and SOIC packages
EL11V, the EP11U is ideally suited for those applications
which require the ultimate in AC performance.
The differential inputs of the EP11U employ clamping
circuitry to maintain stability under open input conditions.
If the inputs are left open, the Q outputs will go LOW.
