Description and Introduction

Voltage-Controlled Oscillators The SN54LS628J is a voltage-controlled oscillator (VCO) manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Series:** SN54LS  
- **Type:** Voltage-Controlled Oscillator (VCO)  
- **Package:** Ceramic DIP (Dual In-Line Package)  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Output Frequency Range:** Adjustable via external components (varies with application)  
- **Logic Family:** LS (Low-Power Schottky)  

### **Descriptions:**  
The SN54LS628J is a precision voltage-controlled oscillator designed for military and industrial applications requiring high reliability. It generates a square wave output whose frequency is controlled by an external voltage input. The device is part of the SN54LS series, which is known for its robustness in harsh environments.  

### **Features:**  
- **Voltage-Controlled Operation:** Output frequency varies with input control voltage.  
- **Wide Operating Temperature Range:** Suitable for extreme conditions.  
- **Low-Power Schottky (LS) Technology:** Balances speed and power efficiency.  
- **Ceramic Package:** Ensures durability in high-reliability applications.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Adjustable Frequency Range:** Configured using external resistors and capacitors.  

This information is strictly based on the device's datasheet and manufacturer-provided details.

Alternative Part Number

  • MC74LS628N --: Same LS628 voltage-controlled oscillator function in a DIP package, pin-compatible with the SN54LS628J and widely available.
  • DM74LS628N --: Direct LS628 VCO equivalent from a different series prefix, same logic family and DIP footprint for drop-in replacement.
  • SN74LS628N --: Commercial-temperature version of the same LS628 VCO from TI, functionally identical with a different prefix and wider availability.
  • MC14538BCP --: Dual precision monostable multivibrator with similar timing and trigger functions, widely used as a functional substitute for the LS628 voltage-controlled oscillator in timing circuits.
  • CD74HC221E --: High-speed CMOS dual monostable multivibrator offering comparable timing control and logic compatibility, suitable for replacing the LS628 in many pulse-generation applications.
  • 74LS123 --: Dual retriggerable monostable multivibrator in the same LS logic family, providing similar timing and output pulse generation capability as a practical alternative.
