SN74CBT16245CDL

Overview

The SN74CBT16245CDL is a 16-bit FET bus switch manufactured by Texas Instruments. It operates with a supply voltage range of 2.7 V to 3.6 V and features low ON-state resistance. The device provides -2 V undershoot protection, ensuring robust performance in high-speed digital applications. It utilizes a 48-pin SSOP package and supports non-inverting logic functionality.

Feature Summary

• Provides 16-bit bidirectional data transfer capability
• Includes -2 V undershoot protection for signal integrity
• Features low ON-state resistance for efficient switching

Applications

• High-speed data bus switching
• Memory module interfacing
• Portable equipment internal communication

Procurement Notes

Verify the specific suffix 'CDL' corresponds to the SSOP-48 package variant. Confirm that the -2 V undershoot protection specification aligns with your system's input requirements. Ensure the operating temperature range meets your environmental constraints before finalizing procurement.

Selection Notes

Select this component when a 16-bit wide bus interface is required with low insertion loss. The -2 V undershoot tolerance makes it suitable for systems experiencing signal ringing or ground bounce. Compare propagation delay specifications against other LVTH or AHCT series alternatives if timing margins are critical.

Part Context

This part belongs to the SN74CBT16245C family of 16-bit FET bus switches. It is designed as a cost-effective solution for replacing mechanical relays or discrete transistor switches in compact electronic designs requiring high-density interconnects.

Replacement Considerations

SN74CBT16245CDLRG4 is a verified lead-free replacement within the same package and electrical specification family.
