SN74AVCH2T45DCUR

Translators, Level Shifters Overview

The SN74AVCH2T45DCUR is a dual-bit, dual-supply bus transceiver manufactured by Texas Instruments. It features configurable voltage translation between two independent power domains, supporting VCCA and VCCB ranges from 1.2 V to 3.6 V. The device provides three-state outputs and operates within an ambient temperature range of -40°C to +85°C. Packaged in an 8-pin VSSOP (DCU) surface-mount format, it supports data rates up to 500 Mbps with a propagation delay of 5.4 ns.

Translators, Level Shifters Feature Summary

• Configurable voltage translation allows seamless interfacing between logic families operating at different supply voltages without external level-shifting components.
• Dual-supply architecture enables independent power domain management for A-side and B-side circuits, optimizing power consumption in mixed-voltage systems.
• Three-state outputs provide high-impedance states to prevent bus contention when the device is disabled or during bidirectional data transfers.

Translators, Level Shifters Applications

• Mobile handheld devices requiring low-power voltage translation between core logic and peripheral interfaces.
• Consumer electronics utilizing mixed-voltage buses such as I2C, SPI, or UART connections.
• Industrial control systems interfacing 1.2 V microcontrollers with 3.3 V sensors or actuators.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DCUR' corresponds to the 8-pin VSSOP package with tape-and-reel orientation. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) requirements against your assembly process specifications. Ensure the ordering part number matches the exact pinout and electrical characteristics defined in the latest Texas Instruments datasheet revision.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation is required between two voltage domains within the 1.2 V to 3.6 V range. The dual-bit configuration suits applications needing minimal footprint compared to quad-bit alternatives. Consider the 5.4 ns propagation delay and 500 Mbps data rate capability for high-speed interface needs. The VSSOP package is suitable for space-constrained printed circuit board designs.

Translators, Level Shifters Part Context

This device belongs to the SN74AVCH2T45 family of advanced CMOS logic products designed for low-voltage operation. It complements other members like the SN74AVCH2T45DCTR and SN74AVCH2T45DCUT, which share identical electrical functionality but differ in packaging types such as SM8 or VSSOP reel configurations. The family targets portable and battery-powered applications requiring efficient power management.

Translators, Level Shifters Replacement Considerations

Publicly confirmed substitute part numbers include SN74AVCH2T45DCTR and SN74AVCH2T45DCUT. These variants offer equivalent electrical performance and functionality. Verify that the alternative package type (e.g., SM8 vs. VSSOP) fits the existing PCB footprint or requires layout modification before substitution.
