3V power.
The SY89321L is functionally equivalent to the SY100EPT21L, but in an ultra-small 8-pin MLF® package that features a 70% smaller footprint.
This ultra-small package and low skew single gate design make the SY89321L ideal for applications that require the translation of a clock or data signal where minimal space, low power and low cost are critical.
VBB allows a differential, single-ended, or AC-coupled interface to the device.
If used, the VBB output should be bypassed to VCC with 0.
01µF capacitor.
Under open input conditions, the /IN will be biased at a VCC/2 voltage level and the IN input will be pulled to ground.
This condition will force the Q output low to provide added stability.
The SY89321L is compatible with positive ECL 100k logic levels.
