SN74AXCH1T45DBVR

Translators, Level Shifters Overview

The SN74AXCH1T45DBVR is a single-bit dual-supply bus transceiver from the Texas Instruments AXC logic series. It operates within a supply voltage range of 650 mV to 3.6 V and supports data rates up to 500 Mb/s. The device features a propagation delay of 152 ns and draws a working supply current of 14 uA. Housed in a SOT-23-6 package, it provides three-state outputs and functions across an extended temperature range from -40°C to +125°C.

Translators, Level Shifters Feature Summary

• Supports dual-supply operation for voltage level translation between dissimilar logic families
• Provides configurable direction control for bidirectional data transfer
• Features over-voltage tolerant inputs to protect against high-voltage signals

Translators, Level Shifters Applications

• Connecting low-voltage processors to higher-voltage peripheral interfaces
• Bidirectional voltage translation in embedded systems with mixed-signal domains
• Level shifting between different power rails in portable electronic devices

Translators, Level Shifters Procurement Notes

Verify the specific suffix DBVR corresponds to the SOT-23-6 surface-mount package and tape-and-reel orientation required for your assembly process. Confirm that the operating temperature range of -40°C to +125°C meets your environmental specifications. Ensure compatibility with the 650 mV minimum supply voltage for your target application circuit design.

Translators, Level Shifters Selection Notes

Select this component when ultra-low voltage operation below 1.2 V is required, distinguishing it from standard LVC or AVC families. Consider the 152 ns propagation delay as a limiting factor for high-speed synchronous interfaces compared to faster alternatives. Evaluate the 14 uA quiescent current for battery-powered applications where standby power consumption is critical.

Translators, Level Shifters Part Context

This part belongs to the SN74AXCH1T45 family, representing Texas Instruments' advanced CMOS technology optimized for very low voltage applications. It serves as a successor to older generation translators, offering improved performance at lower supply voltages while maintaining pin-to-pin compatibility with similar form factors in the broader logic IC portfolio.

Translators, Level Shifters Replacement Considerations

SN74AVCH1T45DBVRG4: Offers similar functionality but operates with a higher minimum supply voltage of 1.2 V and features a significantly faster propagation delay of 5.6 ns.
