SN74LVCC4245ADBR

Translators, Level Shifters Overview

The SN74LVCC4245ADBR is an octal bus transceiver featuring configurable output voltage and three-state outputs. It operates with a VCCA supply of 4.5V to 5.5V and a VCCB supply of 2.7V to 5.5V. The device provides 24mA drive strength at 3V supply, ensuring robust performance for heavier loads. It supports asynchronous communication between data buses with direction control (DIR) and output enable (OE) inputs. The component includes glitch-free power supply sequencing and VCC isolation features, entering a high-impedance state if either supply drops below 100mV. It is housed in a 24-pin SSOP package.

Translators, Level Shifters Feature Summary

• Glitch-free power supply sequencing allows independent powering on or off of supply rails without generating erroneous output transitions.
• VCC isolation and disconnect feature automatically disables I/O outputs when either supply voltage falls below 100mV or remains floating.
• Configurable dual-supply architecture enables translation between 3.3V and 5V environments while maintaining noninverting data transmission.

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 ordering suffix 'DBR' corresponds to the SSOP-24 package and tape-and-reel packaging configuration. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure design compatibility with the recommended operating conditions for both VCCA and VCCB supply rails before finalizing procurement specifications.

Translators, Level Shifters Selection Notes

Select this component when interfacing between 5V logic domains and 3.3V or 5V domains requiring high drive capability. The dual-supply design facilitates seamless integration into mixed-voltage systems without board redesign. Consider the 24mA drive strength for applications involving longer PCB traces or heavier capacitive loads compared to standard logic families.

Translators, Level Shifters Part Context

This device belongs to the SN74LVCC4245A family of octal bus transceivers. It shares functional similarities with the SN74LVC4245 but offers enhanced drive strength and specific voltage translation capabilities. The pinout is compatible with conventional 20-pin devices for data paths, allowing designers to upgrade systems without altering existing board layouts significantly.

Translators, Level Shifters Replacement Considerations

Public confirmed substitute part numbers include SN74LVCC4245APWT and SN74LVCC4245ADW. Verify package compatibility and electrical characteristics match before substitution.
