ICS87004BGI-03LF Datasheet, PDF (1/12 Pages) Integrated Device Technology – LVCMOS/LVTTL FANOUT BUFFER/DIVIDER

LVCMOS/LVTTL FANOUT BUFFER/DIVIDER
PRELIMINARY
ICS87004I-03
GENERAL DESCRIPTION
The ICS87004I-03 is a low skew, ÷1, ÷2 ÷3, ÷4 ÷5,
ICS
÷6 ÷8, ÷16 LVCMOS/LVTTL Fanout Buffer/Divider
HiPerClockS™ _{and a member of theHiPerClockS™ family of High}
Perfor mance Clock Solutions from IDT. The
ICS87004I-03 has selectable clock inputs that
accept single ended input levels. Output enable pin controls
whether the output is in the active or high impedance state.
The ICS87004I-03 is characterized at 3.3V, 2.5V and mixed
3.3V/2.5V, 3.3V/1.8V, 2.5V/1.8V input/output supply operating
modes.Guaranteed bank, output, and par t-to-part skew
characteristics make the ICS87004I-03 ideal for those
applications demanding well defined performance and
repeatability.
