SN74CBT16212ADGVR

Overview

The SN74CBT16212ADGVR is a 24-bit FET bus-exchange switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 4 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device provides TTL-compatible input levels and features low on-state resistance, with maximum values of 20 Ω at 4 V and 12 Ω at 4.5 V. Propagation delay is specified at a maximum of 0.35 ns at 5 V. It utilizes a 56-pin TSSOP package.

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.
• Features low on-state resistance to enable high-speed connections with minimal propagation delay.
• Includes ESD protection that exceeds JESD 22 standards, specifically 200-V machine model performance.

Applications

• High-speed digital bus switching applications
• Data exchanging between multiple signal ports
• Systems requiring TTL-compatible logic interfaces

Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TSSOP-56 package and tape-and-reel quantity of 2000 units. Confirm the component status is listed as Active for new designs. Ensure the datasheet revision matches the required specifications for your application environment.

Selection Notes

Select this component when a 24-bit wide bus interface is required within a compact surface-mount footprint. The device is suitable for designs needing flexible port configuration via external control inputs. Consider the thermal impedance of the TSSOP package if high current loads are anticipated in the design.

Part Context

This part belongs to the Widebus family of bus switches from Texas Instruments. It is designed to provide efficient signal routing in complex digital systems. The device offers a balance of speed and density, allowing for significant bandwidth management in a single integrated circuit package.

Replacement Considerations

SN74CBT16212ADGGR is a direct pin-compatible alternative available in the same TSSOP-56 package but supplied in a standard tube rather than tape and reel.
