SN74CBT16245CDGGR

Overview

The SN74CBT16245CDGGR is a Texas Instruments bus switch featuring two independent 8-bit (16-channel) bidirectional switches. It operates on a single 4.5V to 5.5V supply voltage and utilizes a 48-pin TSSOP package with a 0.240-inch width. The device supports an operating temperature range from -40°C to +85°C and includes ESD protection exceeding 2000V per the Human Body Model specification.

Feature Summary

Provides two independent 8-bit bidirectional data paths for efficient signal routing
Features low on-resistance to minimize signal attenuation across the bus
Includes built-in ESD protection to safeguard against electrostatic discharge events

Applications

High-speed data bus switching in consumer electronics
Signal routing in industrial control systems
Memory interface expansion modules

Procurement Notes

Verify the specific suffix 'CDGGR' to confirm the commercial temperature grade and tape-and-reel packaging format. Ensure the design accommodates the 4.5V to 5.5V supply requirement. Confirm RoHS compliance status matches current manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when a dual 8-bit bidirectional switch is required for 5V logic systems. It serves as a direct replacement for legacy CBT series devices requiring similar pinouts. Consider the TSSOP-48 footprint constraints during PCB layout planning to ensure adequate thermal dissipation and signal integrity.

Part Context

This part belongs to the Texas Instruments 74CBT16245 family of FET-based bus switches. These devices are designed to replace mechanical relays and discrete transistor switches, offering smaller form factors and faster switching speeds. The family provides scalable solutions for managing multiple data lines in complex digital circuits.
