TRANSLATOR

to-LVTTL translator requiring only a single +3.3V power.

The SY89321L is functionally equivalent to the

SY100EPT21L, but in an ultra-small 8-pin MLF

that features a 70% smaller footprint. This ultra-small

package and low skew single gate design make the

SY89321L ideal for applications that require the translation

of a clock or data signal where minimal space, low power

and low cost are critical.

DESCRIPTION

The SY89321L is a differential LVPECL/CML/LVDS-

Under open input conditions, the /IN will be biased at

The SY89321L is compatible with positive ECL 100k
