74LVXC3245MTR

Translators, Level Shifters Overview

The STMicroelectronics 74LVXC3245MTR is an octal dual-supply bus transceiver designed for mixed 3.3V and 5V systems. It operates with VCCA ranging from 2.7V to 3.6V and VCCB from 2.7V to 5.5V, supporting data retention at 1.2V. The device provides a maximum propagation delay of 8ns at 25°C and features symmetrical output impedance with minimum drive currents of 24mA. Quiescent supply current is limited to 5µA maximum. Inputs offer 2kV ESD immunity.

Translators, Level Shifters Feature Summary

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized distribution channels as this part is marked obsolete. Confirm package type compatibility, specifically SO-24 or TSSOP-24, against existing board layouts. Review absolute maximum ratings carefully to prevent damage during integration. Ensure design accounts for the specific operating temperature ranges defined in the datasheet.

Translators, Level Shifters Selection Notes

Select this component when interfacing mixed-voltage buses requires high-speed data transfer with minimal power consumption. The dual-supply capability allows flexible connection between 3.3V and 5V domains without external level shifters. Consider the symmetric output impedance for signal integrity in high-frequency applications where balanced rise and fall times are critical.
