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 Electrical Connection Pin 1 7 8 14 Connection Enable Input Grd & Case Output VDD • 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)
Dimensions are in inches and (MM)
