Product Summary

The SN74LS628N is a voltage-controlled oscillator. The voltage controlled ocillator is improved version of the original VCD. The SN74LS628N features improved voltage to frequency linearity, range and compensation. With the exception of the SN74LS628N it features two independent VCOs in a single monolithic chip.

Parametrics

SN74LS628N absolute maximum ratings: (1)Frequency: 1.1 MHz to 25 MHz; (2)Voltage - Supply 4.75 V ~ 5.25 V ; (3)Minimum Operating Temperature: 0℃; (4)Maximum Operating Temperature: +70℃; (5)Duty Cycle (Max): 50 %; (6)Load Capacitance: 45 pF; (7)Mounting Style: Through Hole; (8)Standard Pack Qty: 25.0; (9)Supply Voltage (Max): 5.25 Volts; (10)Supply Voltage (Min): 4.75 Volts.

Features

SN74LS628N features: (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.
