NTE1581
Integrated Circuit
CMOS, Frequency Divider/Counter for VCR
Description:
The NTE1581 is a frequency divider manufactured by aluminum CMOS technology. It produces a fre-
quency 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 Oscilla-
tion Output
Dwww.DataSheet4U.com Derives a Vertial Scanning Frequency from TV Color Subcarrier
Applications:
D Frequency Divider for VTR
