SN74LS629N

The SN74LS629N from Texas Instruments is a dual voltage-controlled oscillator (VCO) integrated circuit designed for clock and timing applications. This device operates within a supply voltage range of 4.75V to 5.25V and can generate frequencies up to 20MHz.

These VCOs are improved versions of earlier families, offering enhanced voltage-to-frequency linearity, range, and compensation. The SN74LS629N features two independent VCOs on a single monolithic chip. The output frequency of each VCO is determined by a single external component, such as a capacitor or crystal, in conjunction with voltage-sensitive inputs for frequency control and range.

The device is housed in a 16-PDIP package, suitable for through-hole mounting. It operates within a temperature range of 0°C to 70°C and has a typical current consumption of 35 mA. Separate supply voltage pins are provided for isolation between frequency control inputs and the output circuitry, contributing to highly stable operation.

This component is part of the LS technology family and is designed for applications requiring stable and controllable oscillation frequencies. Its dual VCO configuration and separate supply pins offer design flexibility and improved system isolation.
