The SY89306V and SY89316V are a high-speed buffer/
receivers. The devices are functionally equivalent to the
10/100EP16 buffers, but feature a 70% smaller footprint.
The SY89306/316V includes a V
BB
reference for single-
ended AC-coupling applications. Whenever used, the V
BB
pin should be bypassed to ground via a 0.01
F capacitor.
V
BB
reference can only sink/source 0.5mA.
Under open input conditions (pulled to V
EE
), internal
input clamps will force the Q output LOW.

Notes:
1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied at
conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions for extended periods
may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
