Full Size Clock Oscillators TTL Compatible

XO-53

Vishay Dale

The XO-53 series oscillator is TTL compatible and features

fast rise/fall times with high reliability at low cost. The metal

package with pin 7 case ground acts as shielding to

minimize EMI radiation.

FEATURES

• 10 TTL output load

• Size: 14 pin full size

• Industry standard

• Wide frequency range

•Low cost

• Resistance weld package

• Compliant to RoHS Directive 2002/95/EC

• Halogen-free according to IEC 61249-2-21 definition
