Overview
The SN74CBT16861DL is a 20-bit FET bus switch manufactured by Texas Instruments, housed in a 48-pin SSOP (DL) package. It operates within a supply voltage range of 4 V to 5.5 V and supports an operating temperature from -40°C to 85°C. The device features a maximum on-state resistance of 22 Ohms at VCC = 4 V and a typical propagation delay of 0.25 ns at VCC = 5 V. It includes latch-up performance exceeding 100 mA per JESD 78, Class II.
Feature Summary
- Provides high-speed TTL-compatible bus switching with low on-state resistance for minimal propagation delay.
- Organized as one dual 10-bit switch with separate output-enable inputs for independent port control.
Applications
- High-speed data routing between ports
- Bus switching applications requiring TTL compatibility
- Portable equipment utilizing widebus family components
Procurement Notes
Verify the DL suffix corresponds to the SSOP package when ordering. Confirm that the specific revision level matches your design requirements, as datasheet revisions may occur. Ensure all unused control inputs are tied to VCC or GND to maintain proper operation. Check for RoHS compliance status if environmental regulations apply to your assembly process.
Selection Notes
Select this component for designs requiring 20-bit parallel switching capability in a single package. The SSOP package offers a compact footprint suitable for space-constrained layouts. Consider the 4V to 5.5V operating range to ensure compatibility with your system's power supply rails and logic levels.
Part Context
This part belongs to Texas Instruments' Widebus family, designed for efficient data transfer across multiple lines. The SN74CBT16861 series provides a cost-effective solution for managing bidirectional data flow in digital systems without significant signal degradation or timing loss.

FAQ
What is the function of the OE input?
When OE is low, the switch connects Port A to Port B. When OE is high, the switch disconnects the ports, placing them in a high-impedance state.
How is the on-state resistance measured?
On-state resistance is determined by the lowest voltage of the two terminals (A or B) and is measured by the voltage drop between them at a specified current.
