SC-142A Datasheet | Unknown Manufacturer

Description The SC-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS patible signals for bus connected systems. Supplying Pin 1 of the SC-1420 units with a logic “1" or open enables its Pin 3 output. In the disable mode, Pin 3 presents a high impedance to the load. Features - Wide frequency range- 1.0MHz to 80.0MHz - User specified tolerance available - Will withstand vapor phase temperatures of 253°C for 4 minutes maximum - Space-saving alternative to discrete ponent oscillators - High shock resistance, to 1000g - Low Jitter - No internal PLL avoids cascading PLL problems - Metal lid electrically connects to ground to reduce EMI - Gold plated pads Electrical Connection Pin 1 2 3 4 Connection Enable/Disable Ground Output VDD 357 Beloit Street, P.O.
