SN74CBT16212ADL

Overview

The SN74CBT16212ADL is a 24-bit FET bus-exchange switch from the Widebus family, housed in a 56-pin SSOP (DL) package. It operates on a single supply voltage ranging from 4 V to 5.5 V within an industrial temperature range of -40°C to +85°C. The device provides low on-state resistance, typically 7 Ω at VCC = 4.5 V and 12 Ω at VCC = 4 V. Propagation delay is specified at 0.35 ns maximum at VCC = 5 V. It features TTL-compatible input levels and latch-up performance exceeding 250 mA per JESD 17.

Feature Summary

• Functions as either a 24-bit bus switch or a 12-bit bus exchanger utilizing three data-select terminals for routing signals between four ports.
• Provides high-speed switching with minimal propagation delay due to low on-state resistance characteristics.
• Includes ESD protection that exceeds JESD 22 standards, specifically 200-V Machine Model ratings.

Applications

• High-speed digital bus switching applications
• Data exchanging between multiple signal ports
• TTL-compatible logic interface circuits

Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP-56 tube packaging configuration. Confirm the operating temperature range matches the -40°C to +85C specification required for your application environment. Ensure control inputs are tied to VCC or GND to prevent undefined states during operation.

Selection Notes

Select this component when a 24-bit wide bus architecture requires dynamic signal routing between four distinct ports. The device is suitable for systems demanding TTL-compatible logic levels and low insertion loss. Consider the 56-pin SSOP package constraints regarding PCB space and thermal management requirements for surface-mount assembly.

Part Context

This part belongs to Texas Instruments' Widebus family of bus-exchange switches. It shares functional similarities with other members like the SN74CBT16212ADGGR but differs in package type. The DL suffix specifically denotes the shrink small-outline package variant designed for high-density board layouts.

Replacement Considerations

SN74CBT16212ADLR offers identical electrical specifications but utilizes tape-and-reel packaging instead of tubes. SN74CBT16212ADGGR provides the same functionality in a TSSOP-56 package. Verify pinout compatibility before substituting packages.
