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 units 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 to 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)
