TC7SPN3125TU,LF

Translators, Level Shifters Overview

The TC7SPN3125TU is a low-voltage, low-power 1-bit dual-supply bus buffer fabricated with silicon gate CMOS technology. It provides level conversion between A-bus voltages of 1.2 V, 1.5 V, 1.8 V, or 2.5 V and B-bus voltages of 1.8 V, 2.5 V, or 3.3 V. The device features overvoltage tolerant inputs and outputs up to 3.6 V, power-down protection, and an enable input (OE) for signal isolation. Propagation delay ranges from 13.7 ns at VCCA=2.5V/VCCB=3.3V to 43 ns at VCCA=1.2V/VCCB=1.8V. It operates within -40°C to 85°C in a UF6 package.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel configuration. Confirm that the UF6 package dimensions align with the target PCB footprint. Ensure design compliance with absolute maximum ratings, particularly regarding simultaneous supply application on VCCA and VCCB pins during power-off states. Validate operating temperature range requirements against the specified -40°C to 85°C limit.

Translators, Level Shifters Selection Notes

Select this component when interfacing disparate logic families requiring bidirectional or unidirectional level shifting between low-voltage and standard voltage domains. Consider the propagation delay specifications relative to the target bus speed and supply voltage combinations. Evaluate the UF6 package size constraints against available board space. Verify that the 3.6 V tolerance meets the maximum voltage levels present on the connected buses.
