TTL TRI-STATE HIGH FREQUENCY CLOCK OSCILLATOR F1100HT The F1100HT Clock Oscillator is designed to drive high frequency TTL applications (up to 10 TTL gates). This part has a tri-state enable/disable function on pin 1 to facilitate testing with automatic test equipment (ATE). • PART NUMBER SELECTION FEATURES High Frequency TTL Fast Rise/Fall Times 45/55 Symmetry (1.544 ~ 80 MHz) Tri-state Enable/Disable Frequency Stability ±100PPM ±50PPM (to 90 MHz) ±25PPM (to 50 MHz) Part Number F1100HT F1145HT F1144HT Note: -40ºC ~ +85ºC "R" version available (ex: F1100HTR) to 90 MHz Actual Size Discontinued OSCILLATORS • ELECTRICAL CHARACTERISTICS (Ta = 25°C, VDD = 5.0V, RL =400W) PARAMETERS Frequency Range Frequency Stability Temperature Operating Storage Supply Voltage Input Current FREQUENCY RANGE (Fo) (TOPR) (TSTG) (VDD) (IDD) Output Symmetry Rise Time Fall Time Output Voltage Output Current Output Load Start-up Time (TR) (TF) (VOL) (VOH) (IOL) (IOH) (TS) 1.544 1.544 1.544 1.544 25.000+ 50.000+ 80.000+ 1.544 80.000+ 1.544 ~ 110.000 ~ 110.000 ~ ~ ~ ~ ~ ~ ~ ~ 110.000 25.000 50.000 80.000 110.000 80.000 110.000 110.000 1.544 ~ 110.000 1.544 ~ 110.000 1.544 1.544 ~ 110.000 ~ 110.000 CONDITIONS All Conditions* 1.4V Level 0.4V to 2.4V 2.4V to 0.4V IOL = 16 mA IOH = -4 mA VOL = 0.4 V VOH = 2.4 V RL = 400Ω 1.544 -100 MIN 110.000 +100 MAX UNITS -10 -55 +4.5 +70 +125 +5.5 16 30 60 75 55 60 5 5 0.4 ºC 45 40 2.4 * Inclusive of 25ºC tolerance, operating temperature range, input voltage change, load change, aging, shock, and vibration. ***An internal pullup resistor from pin 1 to pin 14 allows active output if pin 1 is left open.
