XOR gate, quad, 4.75 ... 5.25 V, DIL-14

Description
These voltage-controlled oscillators (VCOs) are improved versions of the origingal 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 asinglie monolithic chip. The 'LS624, 'LS626, and 'LS628 have complementary Z outputs. The output frequency for each VCO is established by a single external component (either a capacitor or crystall) 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.
