Block Diagram
LOW SKEW, 1-TO-12 LVCMOS/LVTTL
FANOUT BUFFER
General Description
The low impedance LVCMOS outputs are designed to drive 50Ω
series or parallel terminated transmission lines. The effective
fanout can be increased from 12 to 24 by utilizing the ability of the
outputs to drive two series terminated lines.
The ICS8312I is characterized at full 3.3V, 2.5V, and 1.8V, mixed
3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply
modes. Guaranteed output and part-to-part skew characteristics
along with the 1.8V output capabilities makes the ICS8312I ideal
for high performance, single ended applications that also require a
limited output voltage.
