BA7615N

Overview

The BA7615N is a video signal switcher manufactured by ROHM Semiconductor, designed for use in VTR and TV applications. It features a built-in 6dB amplifier, a 75Ω driver, and a mute function. The device operates with four inputs (IN1-IN4) and one output (OUT), controlled via three control lines. It supports an operating supply voltage range of 4.5V to 13V and draws a typical operating supply current of 19.5mA. The component dissipates up to 850mW of power and functions within a temperature range of -25°C to +75°C. It is housed in a 10-SIP through-hole package.

Feature Summary

• Integrates a 6dB amplifier and 75Ω driver for video signal conditioning
• Includes a mute function for signal control
• Provides switching capability between four input channels and one output

Applications

• Video Tape Recorder (VTR) systems
• Television (TV) signal routing
• Video signal switching circuits

Procurement Notes

Verify end-of-life status before design finalization, as discontinuance notifications may apply. Confirm RoHS compliance details directly from the manufacturer's documentation. Ensure the 10-SIP through-hole package fits the target PCB layout constraints. Validate that the 4.5V to 13V supply range aligns with system power requirements. Check for recommended alternative parts if long-term availability is critical.

Selection Notes

Select this component when a dedicated video switch with integrated amplification is required. The 75Ω driver impedance matches standard video transmission lines. The 6dB gain helps compensate for signal loss in switching paths. Consider the 10-SIP package size for through-hole assembly processes. Evaluate the single-output architecture against multi-output system needs.

Part Context

This part belongs to ROHM Semiconductor's video IC family, specifically categorized under video signal switches and multiplexers. It serves as a specialized solution for analog video routing in consumer electronics. The device complements other video processing components by handling signal selection and basic amplification. Its design focuses on simplicity and direct integration into video signal chains.

Replacement Considerations

Check for official recommended alternatives listed in the datasheet or discontinuance notices. Verify pin compatibility and electrical specifications if substituting with similar video switches. Ensure the replacement maintains the 75Ω output impedance and 6dB gain characteristics if required.
