TL52055DR

Analog Switches - Special Purpose Overview

The TL52055DR is a wide-bandwidth, 2-input, 1-output, 3-circuit video switch manufactured by Texas Instruments. It utilizes BiCMOS technology and operates within a supply voltage range of 4.5 V to 9 V. The device provides no signal loss (0 dB) up to a frequency bandwidth of 40 MHz at VCC = 5 V. Electrical characteristics include a typical operating current of 10.3 mA at 9 V and 9.4 mA at 5 V. Switch crosstalk and channel crosstalk are specified at -75 dB at 4.43 MHz. Differential gain and differential phase are both limited to 0.3%. The component is housed in a 16-pin SOIC package.

Analog Switches - Special Purpose Feature Summary

• Supports switching of separate video signals and component-video signals for high-quality AV systems
• Features low crosstalk and maintains signal integrity without loss up to 40 MHz
• Includes latch-up performance exceeding 250 mA per JESD 17 standard

Analog Switches - Special Purpose Applications

• Digital TV, LCD TV, PDP TV, and CRT TV systems
• VCR, projector, and DVD player applications
• Component-video signaling in consumer electronics

Analog Switches - Special Purpose Procurement Notes

Verify the current marketing status before procurement, as the TL52055DR is listed as obsolete in official documentation. Confirm availability through authorized distributors or check for lifetime-buy periods if existing stock is required. Ensure that the specific ordering suffix matches the desired packaging format and verify RoHS compliance details against the latest environmental data sheets prior to finalizing orders.

Analog Switches - Special Purpose Selection Notes

Select this component for designs requiring wide-bandwidth video switching with minimal signal degradation. Ensure the design accommodates the 4.5 V to 9 V supply range and the specific control input voltage requirements relative to VCC. Consider the obsolete status when planning long-term production runs and evaluate alternative devices if new design implementation is intended.

Analog Switches - Special Purpose Part Context

The TL52055 belongs to the TL520 family of wide-bandwidth video switches from Texas Instruments. It is functionally similar to parts such as the M52055, NJM2283, MM1231, and BA7602. The DR suffix indicates the SOIC package variant supplied in tape and reel format, distinguishing it from tube-packaged versions like the TL52055D.

Analog Switches - Special Purpose Replacement Considerations

Functionally similar part numbers include M52055, NJM2283, MM1231, and BA7602. Verify pin compatibility and electrical specifications against these alternatives before substitution.

Analog Switches - Special Purpose FAQ

What is the maximum frequency bandwidth of the TL52055DR?

The device provides no loss (0 dB) up to a frequency bandwidth of 40 MHz when operated at a supply voltage of 5 V.

How is the control logic configured for the TL52055DR?

The select inputs (1C, 2C, 3C) control the signal path between the A port and B port to the Y port. A High level connects A to Y, while a Low level connects B to Y.

What is the recommended output drive current for the TL52055DR?

When using this device, the output drive current should be maintained at 5 mA or less to ensure proper operation.
