SN74CBT16800CDL

Overview

The SN74CBT16800CDL is a high-speed, TTL-compatible FET bus switch manufactured by Texas Instruments. It features 20 channels configured as ten 1:1 single-pole single-throw (SPST) switches. The device operates at a supply voltage of 5 V and includes precharged outputs to minimize switching noise. It provides –2-V undershoot protection for robust signal integrity. The component is housed in a 48-pin SSOP package and supports surface-mount installation.

Feature Summary

• Features ten independent 1:1 SPST FET bus switches for parallel data routing
• Includes precharged output architecture to reduce transient current spikes during switching
• Provides –2-V undershoot protection to safeguard against input signal anomalies
• Maintains low ON-state resistance for efficient signal transmission

Applications

• High-speed data bus switching in computer systems
• Signal routing in telecommunications equipment
• Interface bridging between different logic families
• Data acquisition systems requiring low distortion

Procurement Notes

Verify the specific ordering suffix DL confirms the 48-pin SSOP package configuration. Ensure the revision level matches your design requirements. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement. Cross-reference the full part number with distributor catalogs to ensure exact component matching.

Selection Notes

Select this component when designing 5-V logic interfaces requiring twenty isolated switching paths. The 48-pin SSOP package suits applications needing high channel density in compact footprints. Consider the precharged output feature if minimizing electromagnetic interference is critical. Verify that the TTL compatibility aligns with your system's input logic levels.

Part Context

This device belongs to the SN74CBT series of bus switches from Texas Instruments. It is functionally related to the SN74CBT16800C but differs in packaging. The SN74CBT16800CDL specifically denotes the SSOP variant. This family focuses on high-speed, low-power switching solutions for digital systems.

Replacement Considerations

The SN74CBT16800C is the functional equivalent within the same series. However, pinout and package dimensions differ due to the SSOP versus other package types. Verify mechanical fit and electrical parameters before substitution.
