F1144H

TTL CLOCK OSCILLATOR F1100H The F1100H Clock Oscillator is TTL compatible. It has been designed for low current consumption and fast rise time. Its standard 45/55% symmetry allows it to directly drive microprocessors that previously used a divide-by-2 stage in applications up to 50MHz. The package is all metal with pin 7 as case ground which provides shielding to help minimize EMI radiation.
