NTH/NTT Series, Type H
Crystal Clock Oscillator
3.3 & 5V, HCMOS, TTL, SMD
Product Description
A crystal controlled, 3.3 or 5 volt, low current
oscillator designed to drive low power, high
performance microprocessors. The plastic-molded
surface mountable package is ideal for today’s
automated assembly environments. J-leads are
compatible with EIA standard footprints. The
HCMOS device is capable of driving both CMOS
and TTL loads.
Frequency Range:
• 1 MHz to 70 MHz
Temperature Range:
• Operating: 0 to +70°C or -40 to +85°C
• Storage: –55 to +125°C
Frequency Stability Tolerance:
±50 or ±100 ppm over all conditions: calibration tolerance,
operating temperature, input voltage change, load change, aging,
shock and vibration.
Product Features
• Footprint compatible and direct replacement for
SG615 series
• Frequency range from 1 to 70 MHz
• 3.3V and 5V operations
• Tri-State output standard
• EIA standard SO-J-20 foot-print
