SN74LVCC4245APWRE4

Translators, Level Shifters Overview

The SN74LVCC4245APWRE4 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, enabling translation between 3.3V and 5V environments. The device features robust glitch-free power supply sequencing and VCC isolation, disabling I/Os if either supply drops below 100mV. It provides a high drive strength of 24mA at 3V supply and includes ESD protection exceeding 2000V HBM and 1000V CDM. The component supports asynchronous communication and is specified for partial-power-down applications using Ioff.

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 feature automatically disables all I/O outputs and enters a high-impedance state when either supply voltage falls below 100mV or remains floating.
• High drive capability delivers 24mA output current at a 3V supply, supporting heavier loads and longer PCB traces.
• Control input logic levels are referenced to the VCCA voltage, facilitating reliable direction control in mixed-voltage systems.

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free and RoHS-compliant manufacturing standards as defined by Texas Instruments. Confirm that the TSSOP-24 package dimensions align with the target PCB footprint requirements. Ensure design implementation accounts for the recommended operating conditions regarding supply voltage ranges and thermal characteristics to maintain device reliability.

Translators, Level Shifters Selection Notes

Select this component when interfacing buses between 5V and 3.3V domains requiring high drive strength and robust power sequencing. The dual-supply architecture supports asynchronous data transfer with configurable direction control. Consider the VCC isolation feature for applications requiring safe partial-power-down states. Verify compatibility with existing logic families and ensure unused inputs are properly biased to prevent undefined operational states.
