TC7SP3125TU,LF

Translators, Level Shifters Overview

The TC7SP3125TU is a low-voltage, low-power 1-bit dual-supply bus buffer fabricated with advanced high-speed CMOS technology. It interfaces between a 1.2 V to 2.5 V A-bus and a 1.8 V to 3.3 V B-bus. 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 6.8 ns at VCCA=2.5V/VCCB=3.3V to 30 ns at VCCA=1.2V/VCCB=1.8V. Output current capability is 12 mA min at VCCB=3.0V. Operating temperature range is -40°C to 85°C.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and marking configuration. Confirm RoHS compliance status and environmental declarations with the manufacturer prior to procurement. Ensure the UF6 package dimensions align with the target PCB footprint constraints.

Translators, Level Shifters Selection Notes

Select this component for applications requiring bidirectional data transfer between disparate voltage domains. Evaluate propagation delay specifications against the system clock requirements for the specific VCCA and VCCB operating points. Consider the ultra-small UF6 package size if board space is limited in portable electronics designs.

Translators, Level Shifters Part Context

This part belongs to Toshiba's TC7SP series of low-voltage CMOS digital integrated circuits. It functions specifically as a single-bit bus transceiver designed for voltage translation. The UF6 package provides a compact solution compared to standard small-outline packages, targeting space-constrained mobile and handheld electronic devices.

Translators, Level Shifters Replacement Considerations

Check for pin-compatible alternatives within the same Toshiba family that may offer updated packaging or revised electrical characteristics. Verify that any substitute maintains the same dual-supply voltage tolerance and overvoltage protection ratings.

Translators, Level Shifters FAQ

Can unused inputs be left floating?

No. Unused inputs and bus inputs must be tied to either VCC or GND to ensure normal operation.

What is the maximum voltage tolerance for inputs and outputs?

All inputs and outputs are designed with overvoltage tolerance up to 3.6 V.
