BUF634FKTTTE3

Overview

The BUF634FKTTTE3 is a high-speed buffer amplifier manufactured by Texas Instruments. It provides a 250 mA output current capability and operates within a supply voltage range of ±2.25 V to ±18 V (4.5 V to 36 V). The device features a bandwidth of 180 MHz and a slew rate of 2000 V/µs. It is housed in a TO-263 (DDPAK-5) package with an operating temperature range from -40°C to 125°C.

Feature Summary

• High-speed buffering with 180 MHz bandwidth
• 250 mA output drive capability
• Wide single or dual supply operation

Applications

• Video signal buffering
• High-speed data line termination
• Driving capacitive loads

Procurement Notes

Verify the exact suffix FKTTTE3 against official Texas Instruments documentation to confirm pinout, thermal pad configuration, and RoHS compliance status. Ensure the ordering part number matches the specific package variant required for your PCB layout and thermal management design.

Selection Notes

Select this component when a high-current buffer is needed for driving transmission lines or heavy capacitive loads. Compare the 180 MHz bandwidth and 250 mA drive against the upgraded BUF634A if higher speed or lower noise is required. Verify that the TO-263 package fits the available board space and thermal constraints.

Part Context

This part belongs to the BUF634 family of high-speed buffers originally developed by Burr-Brown and acquired by Texas Instruments. It serves as a robust solution for applications requiring significant current drive without sacrificing signal integrity at high frequencies.

Replacement Considerations

The BUF634A series offers improved performance metrics such as higher bandwidth and lower noise. Verify electrical compatibility before substituting.
