SN74S124 双路压控震荡器
The 'S124 features two independent voltage-controlled oscillators (VCO) in a single monolithic chip. The output frequency of each VCO is established by an external capacitor in combination with two voltage-sensitive inputs, one for frequency range and one for frequency control. These inputs can be used to vary the output frequency as shown under typical characteristics. These highly stable oscillators can be set to operate at any frequency typically between 0.12 hertz and 85 megahertz.
While the enable input is low, the output is enabled. While the enable input is high, the output is high.
These devices can operate from a single 5-volt supply. 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 (
GND) and is provided for the oscillator and associated frequency-control circuits so that effective isolation can be accomplished in the system
