Additional Information

  • Summary
  • Tech Specs
  • Reviews
The NTE74LS624 is a voltage controlled oscillator in a 14-lead plastic DIP-type package that is an improved version of the original NTE 74LS324 VCO. This new device features improved voltage-to-frequency linearity, range, and compensation 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 as well as one for frequency range. The NTE74LS624 features a 600 internal timing resistor. A single 5V supply can be used; however, one set of supply voltage and ground pins (VCC and GND) is provided for the enable, synchronization-gating and output sections and a separate set (OSC VCC and OSC GND) is provided for the oscillator and associated frequency control circuits so that effective isolation can be accomplished in the system. For operation of frequencies greater than 10MHz, it is recommended that two independent supplies be used. When the enable input is low, the output is enabled; when the enable input is high, the internal oscillator is disabled, Y is high and Z is low. The pulse-synchronization-gating section ensures that the first output pulse is neither clipped nor extended. The duty cycle of the square-wave output is fixed at approximately 50 percent.

Data Sheet
