SN74CBT16245CDGVR

Overview

The SN74CBT16245CDGVR is an octal FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 4V to 5.5V and features bidirectional data transmission across eight independent channels. The device utilizes a 48-pin TVSOP package with a 0.25-inch body width. It supports low-voltage TTL (LVTTL) input levels and includes an active-low enable control function. The component is designed for surface-mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent bidirectional bus switching channels
• Low on-resistance design ensures minimal signal attenuation during conduction
• Active-low enable pin allows precise control over data flow direction and state

Applications

• High-speed data routing in portable consumer electronics
• Signal isolation between different voltage domains in embedded systems
• Bus expansion interfaces in industrial control equipment

Procurement Notes

Verify the specific suffix CDGVR against official Texas Instruments documentation to confirm the exact package type, tape-and-reel specifications, and moisture sensitivity level. Ensure compatibility with existing PCB footprints and reflow soldering profiles before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring efficient management of multiple parallel data lines under a single 5V supply. It serves as a suitable alternative for applications needing compact packaging and reliable signal integrity without the complexity of dual-supply translation mechanisms.

Part Context
