TC7WPN3125FK(T5L,F

Overview

The TC7WPN3125FK is a dual-supply, advanced high-speed CMOS 2-bit bus buffer fabricated with silicon gate CMOS 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-voltage systems. It includes an enable input (OE) for signal isolation and protection circuits against static discharge. The component operates within a wide temperature range of -40°C to 125°C and is housed in an ultra-small US8 package.

Feature Summary

• Dual-supply architecture enabling interface between 1.2-V/1.5-V/1.8-V/2.5-V buses and 1.8-V/2.5-V/3.6-V buses
• Overvoltage-tolerant inputs and outputs rated up to 3.6 V with power-down protection
• High-speed data transmission with propagation delays ranging from 13.7 ns to 43 ns depending on supply conditions
• Ultra-small US8 surface-mount package design suitable for space-constrained portable applications

Applications

• Interface circuits 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
• Battery-driven portable devices such as PDAs and cellular phones
• Mixed-voltage system signal routing and level shifting

Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range, as devices ending in (CT) are rated for -40°C to 85°C while others support -40°C to 125°C. Ensure that no voltage is supplied to the VCCB pin when the VCCA supply is in the OFF state to prevent damage. Confirm that unused inputs are tied to either VCC or GND for normal operation. Check RoHS compliance status if required by environmental regulations.

Selection Notes

Select this component when interfacing logic families with different supply voltages, specifically where A-inputs operate at lower voltages (1.2 V–2.5 V) and B-outputs drive higher voltage buses (1.8 V–3.6 V). Consider the propagation delay requirements relative to the chosen VCCA and VCCB levels, as speed varies significantly with voltage. Ensure the application does not require applying signals to bus pins while the device is in output mode, as this may cause damage.

Part Context

This device belongs to Toshiba's CMOS Digital Integrated Circuits family, specifically designed as low-voltage, low-power bus buffers. It utilizes silicon gate CMOS technology to achieve high-speed performance while maintaining low power dissipation. The product was commercially produced starting in December 2020 and is intended for modern portable electronics requiring efficient voltage translation.
