Description
The HS-A1450 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HS-A1450 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
• Space-saving alternative to discrete component
• High shock resistance, to 3000g
• All metal, resistance weld, hermetically sealed
• 3.3 Volt operation
