SN74CBT16244CDGGR

Overview

The SN74CBT16244CDGGR is a 16-bit FET bus switch manufactured by Texas Instruments. It provides high-speed TTL-compatible switching in a standard pinout configuration. The device consists of four independent 4-bit low-impedance switches with separate output-enable inputs. It operates within a supply voltage range of 4 V to 5.5 V and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16 bits of high-speed bus switching functionality
• Features low on-state resistance for minimal propagation delay
• Organized as four independent 4-bit low-impedance switches
• Supports bidirectional data flow between ports

Applications

• High-speed data routing applications
• Portable systems requiring low power consumption
• Battery-powered consumer electronics
• Communications equipment signal switching

Procurement Notes

Verify the specific ordering suffix 'CDGGR' against official documentation, as datasheets primarily list 'DGGR'. Confirm that the component meets the required industrial temperature specifications (-40°C to +85°C) and ensure all unused control inputs are tied to VCC or GND during operation to maintain proper device function.

Selection Notes

Select this component when a standard 16-bit bus switch topology is required. It is suitable for designs needing bidirectional data transfer with low insertion loss. Ensure the system logic levels are compatible with the specified TTL input thresholds and that the operating voltage remains within the 4 V to 5.5 V range.

Part Context

This part belongs to the Widebus family of bus switches from Texas Instruments. It utilizes a 48-pin TSSOP package (DGG). The device is designed to replace older discrete switching solutions, offering integrated performance in a compact surface-mount form factor suitable for modern PCB layouts.

FAQ

How does the device handle data direction?

Data can flow bidirectionally from port A to port B, or vice versa, when the output-enable input is low.

What happens when the output-enable input is high?

When the output-enable input is high, the switch opens, creating a high-impedance state between the two ports.
