THS7374IPWR

Overview

The THS7374IPWR is a four-channel SDTV video amplifier fabricated using Texas Instruments' SiGe BiCom3X process. It operates on a single supply voltage ranging from 3 V to 5 V and features integrated sixth-order Butterworth low-pass filters with a 9.5-MHz bandwidth, which can be bypassed for a 150-MHz mode. The device provides a fixed 6-dB gain, rail-to-rail output capability, and supports DC-coupled or AC-coupled inputs with sync-tip clamp functionality.

Feature Summary

• Integrated sixth-order Butterworth filter with selectable bypass mode
• Rail-to-rail output stage supporting both AC and DC line driving
• Versatile input biasing including DC coupling and sync-tip clamp options

Applications

• Low-cost SCART systems
• Set-top box output video buffering
• Surveillance systems

Procurement Notes

Verify the specific ordering suffix 'IPWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards and lead-free manufacturing specifications as defined by the manufacturer's green product guidelines before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring multiple channels of SDTV signal processing within a compact footprint. The integrated filtering simplifies design complexity compared to discrete solutions. Ensure the application environment remains within the specified operating temperature range and power supply constraints to maintain optimal signal integrity and performance stability.

FAQ

How does the bypass mode affect the filter characteristics?

Activating the bypass mode disables the internal sixth-order Butterworth filter, allowing the device to operate with a significantly wider 150-MHz bandwidth.

What is the function of the disable pin?

The disable pin controls the operational state of the amplifier; applying a logic high voltage disables the part to minimize power consumption, while a logic low enables normal operation.
