Low Skew, 1-TO-4 LVCMOS / LVTTL 8304-01 Inverting Fanout Buffer PRODUCT DISCONTINUATION NOTICE - LAST TIME BUY EXPIRES MAY 6, 2017 DATASHEET GENERAL DESCRIPTION FEATURES The 8304-01 is a low skew, 1-to-4 Inverting Fanout Buffer. 4 LVCMOS / LVTTL outputs The 8304-01 is characterized at full 3.3V for input V , and DD LVCMOS/LVTTL clock input mixed 3.3V and 2.5V for output operating supply modes (V ). Guaranteed output and part-to-part skew characteris- Maximum output frequency: 166MHz DDO tics make the 8304-01 ideal for those clock distribution Output skew: 50ps (maximum) applications demanding well de ned performance and re- peatability. Part-to-part skew: 600ps (maximum) Small 8 lead SOIC package saves board space 3.3V input, outputs may be either 3.3V or 2.5V supply modes 0C to 70C ambient operating temperature Lead-Free package fully RoHS compliant For functional replacement part use 8304AMLF BLOCK DIAGRAM PIN ASSIGNMENT nQ0 VDDO 1 8 nQ3 VDD 2 7 nQ2 CLK 3 6 nQ1 nQ1 GND 4 5 nQ0 CLK nQ2 8304-01 8-Lead SOIC 3.8mm x 4.8mm x 1.47mm package body nQ3 M Package Top View 8304-01 REVISION D 5/9/16 1 2016 Integrated Device Technology, Inc.8304-01 DATA SHEET TABLE 1.
