These voltage-controlled oscillators (VCOs) are improved versions of the original VCO family: SN54LS124, SN54LS324 thru SN54LS327, SN74LS124, and SN74LS324 thru SN74LS327. These new devices feature improved voltage-to-frequency linearity, range, and compensation. With the exception of the ‘LS624 and ‘LS628, all of these devices feature two independent VCOs in a single monolithic chip. The ‘LS624, ‘LS625, ‘LS626, and ‘LS628 have complementary Z outputs. The output frequency for each VCO is established by a single external component (either a capacitor or crystal) in combination with voltage-sensitive inputs used for frequency control and frequency range. Each device has a voltage-sensitive input for frequency control; however, the ‘LS624, ‘LS628, and ‘LS629 devices also have one for frequency range.
1. Separate Supply Voltage Pins for Isolation of Frequency Control Inputs and Oscillators from Output Circuitry
2. Highly Stable Operation over Specified Temperature and/or Supply Voltage Ranges
