SN74LVCC4245ANSR

Translators, Level Shifters Overview

The SN74LVCC4245ANSR is an octal dual-supply bus transceiver manufactured by Texas Instruments. It features two separate power rails: VCCA operates at 4.5V to 5.5V, while the configurable VCCB port accepts voltages from 2.7V to 5.5V. This architecture enables translation between 3.3V and 5V environments. The device provides noninverting data transmission with configurable output voltage and three-state outputs. It includes robust glitch-free power supply sequencing and VCC isolation features that disable I/Os if either supply drops below 100mV.

Translators, Level Shifters Feature Summary

• Supports asynchronous communication between data buses using separate A and B ports for distinct voltage domains.
• Provides high drive strength suitable for heavier loads and longer PCB traces.
• Features VCC isolation and disconnect capabilities to prevent damaging current backflow during partial-power-down applications.
• Ensures robust performance through glitch-free power supply sequencing regardless of power-on or power-off order.

Translators, Level Shifters Applications

• Data concentrators
• Three phase UPS systems
• Servo drive power stage modules
• Air conditioner outdoor units
• String inverters

Translators, Level Shifters Procurement Notes

Verify the specific package suffix 'ANSR' corresponds to the SOIC-24 tape-and-reel configuration required for your assembly process. Confirm that the component meets RoHS3 standards and matches the manufacturer's latest datasheet revision SCAS584O. Ensure design compatibility with the specified operating temperature range and absolute maximum ratings before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic circuits between 5V and 3.3V domains requiring high drive capability. It is suitable for designs needing independent control over supply rails without strict sequencing requirements. Consider its pinout compatibility with standard 20-pin devices if board space is constrained. Evaluate the need for partial-power-down support and high ESD protection levels in harsh industrial environments.

Translators, Level Shifters Part Context

This part belongs to the SN74LVCC4245A family of octal bus transceivers. It is designed for versatile bus interface applications where output drive strength and trace length are critical factors. The device allows designers to switch between all 3.3V or all 5V configurations without redesigning the board layout, offering flexibility in system architecture.

Translators, Level Shifters Replacement Considerations

The SN74LVC4245A is a compatible alternative within the same product family. Verify pinout alignment and electrical characteristics against the specific application requirements before substitution.
