CMOS
HS-1450 Series
Description
The HS-1450 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HS-1450 unit s with a logic “1" or open enables its pin 8
output. In the disabled mode, pin 8 presents a high impedance to the load. All units are designed to
survive wave soldering operations without damage.
Features
• Wide frequency range– 4.0MHz t o 40.0MHz
• User specified tolerance available
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 3000g
• All metal, resistance weld, hermetically sealed
package
• Low Jitter
• High Q Crystal actively tuned oscillator circuit
• Power supply decoupling internal
• No internal PLL avoids cascading PLL problems
• Low power consumption
• Gold plated leads - Solder dipped leads available
upon request
• TTL compatible (HCT) at specified supply voltage
• RoHS Compliant, Lead Free Construction
(unless solder dipped leads are supplied)
