74LVC241AQ20-13

Overview

The Diodes Incorporated 74LVC241AQ20-13 is an octal buffer and line driver featuring two independent 4-bit non-inverting channels with 3-state outputs. It operates within a supply voltage range of 1.65V to 3.6V, providing high-level output currents up to -24mA and low-level currents up to 24mA at VCC = 3.0V. The device utilizes a QFN-20 (V-QFN4525-20) surface-mount package. Inputs tolerate voltages up to 5.5V, enabling compatibility in mixed-voltage environments. It includes I_OFF circuitry for partial power-down applications and meets ESD protection standards exceeding 2000V Human Body Model.

Feature Summary

• Provides two independent 4-bit non-inverting buffers/drivers with separate output-enable inputs and 3-state capability.
• Features Schmitt trigger action at all inputs to improve noise immunity and signal integrity.
• Includes I_OFF circuitry that disables outputs to prevent damaging current backflow during partial power-down states.
• Inputs accept up to 5.5V, allowing direct interfacing with 3.3V or 5V logic systems.

Applications

• Bus driving
• Power down signal isolation
• General purpose logic

Procurement Notes

Verify the specific suffix 'Q20' confirms the V-QFN4525-20 package type rather than TSSOP-20. Confirm RoHS compliance and Halogen-free status requirements match project specifications. Ensure input pins are tied to valid logic levels when unused to prevent excessive current draw. Validate thermal resistance parameters against PCB layout constraints for the QFN package.

Selection Notes

Select this component for designs requiring octal buffering with mixed-voltage tolerance. The QFN-20 package offers a compact footprint suitable for space-constrained layouts. Verify that the 5.5V input tolerance aligns with upstream logic levels. Consider the I_OFF feature if the system requires safe operation during power-down sequences without external control.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices manufactured by Diodes Incorporated. It serves as an octal variant within the broader 74-series logic ecosystem, specifically designed for high-speed, low-power applications. The AQ20 designation indicates the automotive-grade or enhanced reliability version packaged in a QFN-20 format, distinct from the standard TSSOP-20 variant.

Replacement Considerations

Direct substitutes include other 74LVC241 variants in QFN-20 packages from Diodes Incorporated or equivalent octal bus drivers from other manufacturers offering identical pinouts and electrical characteristics.
