TC7WP3125FC(TE85L)

Overview

The TC7WP3125FC(TE85L) is a dual-supply, advanced high-speed CMOS 2-bit bus buffer fabricated with silicon gate technology. It provides voltage translation between low-voltage buses (1.2 V to 2.5 V) and higher-voltage buses (1.8 V to 3.6 V). The device features overvoltage tolerant inputs and outputs up to 3.6 V, ensuring safe operation in mixed-supply systems. It includes an enable input (OE) for signal isolation and offers power-down protection. The component operates within a temperature range of -40°C to 85°C and utilizes the US8 package.

Feature Summary

• Dual-supply architecture supporting mixed-voltage system interfaces
• Overvoltage tolerant inputs and outputs up to 3.6 V
• Power-down protection capability for all pins
• Enable input allows effective signal line isolation

Applications

• Interface between 1.2-V, 1.5-V, 1.8-V, or 2.5-V buses and 1.8-V, 2.5-V, or 3.6-V buses
• Mixed supply voltage systems requiring level shifting
• Battery-driven applications such as PDAs and cellular phones

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm the operating temperature range. Devices ending in (CT) are rated for -40°C to 85°C, while other suffixes may support -40°C to 125°C. Ensure the selected variant matches the thermal requirements of the target application environment before procurement.

Selection Notes

Select this component when interfacing logic families with different supply voltages, specifically where A-inputs operate at lower levels than B-outputs. Consider the propagation delay specifications relative to the chosen VCCA and VCCB combinations. Verify that the output current drive capabilities meet the load requirements of the destination bus lines.
