NTE1581

NTE1581 Integrated Circuit CMOS, Frequency Divider/Counter for VCR Description: The NTE1581 is a frequency divider manufactured by aluminum CMOS technology. It produces a frequency of 1/59719 or 1/88672 of the input frequency (3.58MHz to 60Hz or 4.43MHz to 50Hz). Features: D Makes Possible a Crystal Oscillator Circuit D Capable of Handling Small−Amplitude Input Signals as low as 0.3Vpp D Frequency−Dividing Ratio Selected Through Terminal N D Reset Function D Produces a Shaped−Waveform Output of the same Frequency as the Input Signal or Oscillation Output www.DataSheet4U.com D Derives a Vertial Scanning Frequency from TV Color Subcarrier Applications: D Frequency Divider for VTR Absolute Maximum Ratings: Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3V to 9V Input Voltage, VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
