GENERAL DESCRIPTION

The 8304I is a low skew, 1-to-4 Fanout Buffer. The 8304I is charac-

terized at full 3.3V for input V

DD

, and mixed 3.3V and 2.5V for output

operating supply modes (V

DDO

). Guaranteed output and part-to-part

skew characteristics make the 8304I ideal for those clock distribution

applications demanding well defined performance and repeatability.

FEATURES

• Four LVCMOS / LVTTL outputs

• LVCMOS clock input

• CLK can accept the following input levels: LVCMOS, LVTTL

• Maximum output frequency: 166MHz

• Output skew: 60ps (maximum)

• Part-to-part skew: 650ps (maximum)

• Small 8 lead SOIC package saves board space

• 3.3V input, outputs may be either 3.3V or 2.5V supply modes

• -40°C to 85°C ambient operating temperature

• Available in lead-free (RoHS 6) compliant package
