NTE74LS624

NTE74LS625 : The NTE74LS625 is a dual voltage controlled oscillator in a 16−Lead plastic DIP type package that is an improved version of the original NTE74LS325 VCO. This new device features improved voltage−to−frequency linearity, range, and compensation as well as two independent VCO’s and has complementary Z outputs. The output frequency is established by a single external capacitor in combination with voltage−sensitive inputs used for frequency control and frequency range. This device has a voltage−sensitive input for frequency control. A single 5V supply can be used; however, one set of supply voltage and ground pins (VCC and GND) is provided fo the enable, synchronization−gating, and output sectio.

NTE74LS629 : The NTE74LS629 is a dual voltage controlled oscillator in a 16−Lead plastic DIP type package that is an improved version of the original NTE74LS124 VCO. This new device features improved voltage−to−frequency linearity, range, and compensation and features two independent VCO’s is a single monolithic chip. The output frequency for each VCO is established by a single external capacitor in combination with voltage−sensitive inputs used for frequency control and frequency range. This device has a voltage−sensitive input for frequency control as well as one for frequency range. A single 5V supply can be used; however, one set of supply voltage and ground pins (VCC and GND) is provided fo the ena.
