SN74CBTS3384PWR

Overview

The SN74CBTS3384PWR is a 10-bit FET bus switch manufactured by Texas Instruments, housed in a 24-pin TSSOP 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 Schottky diode clamping on I/Os to prevent undershoot. Electrical characteristics include a maximum on-state resistance of 7 Ω at VCC = 4.5 V and a typical propagation delay of 0.25 ns at VCC = 5 V.

Feature Summary

• Provides ten bits of high-speed TTL-compatible bus switching with integrated Schottky diodes for input/output undershoot clamping.
• Organized as two independent 5-bit bus switches, each equipped with separate output-enable (OE) inputs for precise control.
• Features low on-state resistance to facilitate signal connections with minimal propagation delay.

Applications

• High-speed data bus routing
• Portable equipment signal switching
• Consumer electronics bus management

Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the active production status aligns with long-term manufacturing availability requirements. Ensure the TSSOP-24 footprint matches the target PCB design guidelines provided in the official datasheet documentation.

Selection Notes

Select this component when designing circuits requiring 10-bit bidirectional data transfer with TTL-compatible logic levels. The inclusion of Schottky diodes makes it suitable for applications where signal integrity protection against undershoot is necessary. Verify that the 4 V to 5.5 V supply voltage range meets the system power specifications.
