DESCRIPTION

■ Differential LVPECL inputs

■ 24mA LVTTL outputs

■ Flow-through pinouts

The SY89321L is a differential LVPECL-to-LVTTL

translator requiring only a single +3.3V power. Because

LVPECL (Low Voltage Positive ECL) levels are used, only

+3.3V and ground are required. The SY89321L is functionally

equivalent to the SY100EPT21L, but in an ultra-small

■ Internal input resistors: pulldown on IN, pulldown

and pullup on /IN

■ Q output will default LOW with inputs open

8-lead MLF package that features a 70% smaller footprint.

■ V output

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.

■ Available in ultra-small 8-pin MLF (2mm x 2mm)

package

allows a differential, single-ended, or AC-coupled

interface to the device. If used, the V output should be

bypassed to V

with 0.01µF capacitor.

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

a V /2 voltage level and the IN input will be pulled to

ground. This condition will force the Q output low to

provide added stability.

The SY89321L is compatible with positive ECL 100k

logic levels.
