Low Skew, 1-to-4 Multiplexed Differential/

LVCMOS-to-LVCMOS/LVTTL Fanout Buffer

ICS8305

DATA SHEET

General Description

The ICS8305 is a low skew, 1-to-4, Differential/ LVCMOS-to-

LVCMOS/LVTTL Fanout Buffer. The ICS8305 has selectable clock

inputs that accept either differential or single ended input levels. The

clock enable is internally synchronized to eliminate runt pulses on

the outputs during asynchronous assertion/deassertion of the clock

enable pin. Outputs are forced LOW when the clock is disabled. A

separate output enable pin controls whether the outputs are in the

active or high impedance state.

Guaranteed output and part-to-part skew characteristics make the

ICS8305 ideal for those applications demanding well defined

performance and repeatability.
