SN74TVC16222DGGR

Specialty Logic Overview

The SN74TVC16222DGGR is a 22-bit voltage clamp digital bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.2 V to 3.6 V and features a maximum on-resistance of 12.5 Ohms with a propagation delay of 4 ns. The device supports bidirectional data transmission and includes voltage clamping on all inputs and outputs to protect against system transients exceeding the supply rails. Designed for surface-mount applications, it is housed in a 48-pin TVSOP package and functions reliably across an operating temperature range from -40°C to +85°C.

Specialty Logic Feature Summary

• Integrates 22-bit bidirectional bus switching capability for high-density data routing
• Provides input and output voltage clamping to safeguard against system transients exceeding supply rails
• Supports low-voltage operation ranging from 1.2 V to 3.6 V for compatibility with diverse logic families

Specialty Logic Applications

• High-speed data bus protection in portable computing devices
• Voltage level translation between different logic domains
• System transient protection for I/O interfaces

Specialty Logic Procurement Notes

Verify the specific suffix 'DGGR' confirms the TSSOP-48 reel packaging variant. Confirm RoHS compliance status through the manufacturer's current documentation. Ensure the design accommodates the specified thermal and electrical characteristics for the intended operating environment.

Specialty Logic Selection Notes

Select this component when 22-bit wide bus switching with integrated overvoltage protection is required. The low on-resistance and fast propagation delay make it suitable for high-speed data lines. Verify that the 1.2 V to 3.6 V supply range aligns with the target system voltage requirements.

Specialty Logic Part Context

This part belongs to the SN74TVC16222A family of 22-bit voltage clamps. It shares functional similarities with other TI bus switches but is distinguished by its specific bit width and integrated clamping diodes. The DGGR suffix denotes the tape-and-reel packaging format used for automated assembly processes.

Specialty Logic Replacement Considerations

Direct substitutes include SN74TVC16222ADGVR and SN74TVC16222ADL, which share identical electrical specifications. Verify package compatibility (TVSOP vs SSOP) before substitution.
