SN74LVCC4245ADWRG4

Translators, Level Shifters Overview

The SN74LVCC4245ADWRG4 is an octal dual-supply bus transceiver with configurable output voltage and 3-state outputs. It operates with VCCA at 4.5V to 5.5V and VCCB at 2.7V to 5.5V. The device provides 24mA drive strength at a 3V supply. It features robust, glitch-free power supply sequencing and VCC isolation. The package is SOIC-24 (DW).

Translators, Level Shifters Feature Summary

• Configurable B port voltage allows translation between 3.3V and 5V environments.
• Glitch-free power supply sequencing prevents erroneous data transitions during power-up or power-down.
• VCC isolation feature disables I/O outputs when either supply rail falls below 100mV or is floating.

Translators, Level Shifters Applications

• Data concentrators
• Three phase UPS
• Servo drive power stage module

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current product status documentation to confirm RoHS compliance details and final availability. Ensure the SOIC-24 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Translators, Level Shifters Selection Notes

Select this component for applications requiring asynchronous communication between buses operating at different voltage levels. The high drive strength supports heavier loads and longer traces. Ensure control inputs are referenced to VCCA and unused inputs are tied to logic high or low to prevent undefined states.

Translators, Level Shifters Part Context

This part belongs to the SN74LVCC4245A family of octal bus transceivers. It is designed for use in systems where data buses operate at different voltage domains, such as translating between 3.3V and 5V logic levels while maintaining signal integrity through high drive capabilities.

Translators, Level Shifters Replacement Considerations

SN74LVC4245A is listed as compatible. Verify pinout alignment and electrical specifications against the original design requirements before substitution.

Translators, Level Shifters FAQ

How does the device handle partial-power-down conditions?

The device includes Ioff circuitry that disables the outputs to prevent damaging current backflow when the device is powered down.

What happens if one supply rail is disconnected while the other is active?

If either VCCA or VCCB is less than 100mV or left floating, all I/O outputs enter a high-impedance state.
