74ACT715SCX

Overview

The onsemi 74ACT715SCX is a programmable video sync generator in a 20-lead SOIC package. It generates horizontal, vertical, and composite sync/blank signals for interlaced and non-interlaced modes. The device supports input clock frequencies exceeding 130 MHz with TTL-compatible inputs. It features 8 mA output drive capability and includes registers for defining pulse widths and timing intervals.

Feature Summary

• Generates horizontal, vertical, and composite sync and blank signals
• Supports interlaced and non-interlaced operation formats
• Allows complete user definition of pulse widths via register programming
• Includes mask-programmed default RS170/NTSC values

Applications

• Television signal generation
• Monitor timing circuits
• Composite sync signal creation

Procurement Notes

Verify the specific suffix 'SCX' indicates the SOIC tape and reel packaging variant. Confirm the manufacturer origin as Fairchild Semiconductor or onsemi through official datasheets. Ensure compatibility with existing TTL logic levels and power supply requirements before integration.

Selection Notes

Select this component for applications requiring precise, programmable video timing control. The ACT family ensures high-speed performance suitable for modern display interfaces. Verify that the required output drive current and voltage levels match the system design specifications.

Part Context
