74LVC1T45DW-7

Translators, Level Shifters Overview

The 74LVC1T45DW-7 is a single-bit dual-supply translating transceiver with 3-state outputs manufactured by Diodes Incorporated. It facilitates logic level translation between voltage domains ranging from 1.65V to 5.5V. The device operates within an ambient temperature range of -40°C to +125°C and utilizes the SOT-363-6 package. Key electrical parameters include a maximum propagation delay of 7.5 ns, a supply current of 4 µA, and output drive capability of ±24 mA at 3.3V.

Translators, Level Shifters Feature Summary

• Supports universal low-voltage translation across independent power supplies for A and B pins
• Provides partial-power-down isolation via IOFF feature when either supply is zero volts
• Includes high noise immunity with typical hysteresis and robust ESD protection ratings

Translators, Level Shifters Applications

• Voltage level translation between logic types operating at different voltages
• Power-down signal isolation to prevent loading on signal lines
• Portable electronics such as cell phones, tablets, and e-readers
• Computing peripherals including hard drives and optical drives

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DW suffix designates the SOT-363 configuration. Confirm compliance with RoHS directives and halogen-free requirements during procurement. Ensure that the selected component aligns with the intended thermal and electrical operating conditions specified in the datasheet.

Translators, Level Shifters Selection Notes

Select this component for applications requiring bidirectional data transfer between dissimilar voltage domains. The DIR pin allows control over data flow direction relative to VCCA. Consider the SOT-363 package dimensions for PCB layout constraints. Evaluate the propagation delay characteristics against system timing requirements to ensure signal integrity.
