SN74AVC1T45YEPR

Translators, Level Shifters Overview

The SN74AVC1T45YEPR is a single-bit noninverting bus transceiver from Texas Instruments utilizing two separate configurable power-supply rails. It operates with VCCA and VCCB voltages ranging from 1.2V to 3.6V, enabling universal low-voltage bidirectional translation between nodes such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device features a propagation delay of 5.6ns and supports data rates up to 500Mbps. It includes an Ioff circuit for partial power-down applications and overvoltage-tolerant inputs. The component is housed in a DSBGA-6 package and functions within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Configurable dual-rail design allows independent voltage selection for A and B ports
• Ioff circuit disables outputs to prevent damage during partial power-down states
• Overvoltage-tolerant inputs protect the device when connected to higher voltage buses

Translators, Level Shifters Applications

• Asynchronous communication between two data buses operating at different voltage levels
• Voltage level translation in portable and battery-powered systems
• Interface bridging between low-voltage processors and peripheral devices

Translators, Level Shifters Procurement Notes

Verify the specific suffix YEPR corresponds to the DSBGA-6 package configuration. Confirm RoHS compliance status and manufacturing origin through official Texas Instruments documentation or authorized distributor certificates. Ensure the ordering part number matches the required package type and tape-and-reel specifications for your assembly process.

Translators, Level Shifters Selection Notes

Select this component when a single-channel bidirectional translator is required between dissimilar voltage domains. The AVC series offers high speed and low power consumption suitable for dense PCB layouts. Consider the DSBGA-6 footprint constraints and thermal requirements. Verify that the DIR input logic level aligns with the controlling microcontroller's output voltage.

Translators, Level Shifters Part Context

This part belongs to the SN74AVC1T45 family of single-bit dual-supply bus transceivers. The family shares core electrical characteristics but varies by package style, such as SOT-23-6 or DSBGA-6. The YEPR suffix specifically denotes the DSBGA-6 surface-mount package variant manufactured by Texas Instruments.
