74LVC241AT20-13

Overview

The 74LVC241AT20-13 is an octal buffer and line driver featuring three-state outputs, manufactured by Diodes Incorporated. It integrates two independent 4-bit buffers with separate output-enable inputs (1OE and 2OE). The device operates within a supply voltage range of 1.65V to 3.6V and supports partial power-down applications via I_OFF circuitry. Inputs tolerate up to 5.5V, enabling mixed-voltage interfacing. It provides 24mA sink or source current at VCC = 3V and includes Schmitt trigger action at all inputs.

Feature Summary

• Provides two independent 4-bit non-inverting buffers with separate output-enable controls for flexible bus driving.
• Supports partial power-down operation through dedicated I_OFF circuitry that disables outputs to prevent damaging backflow currents.
• Features Schmitt trigger action at all inputs to ensure clean signal transitions in noisy environments.
• Inputs accept voltages up to 5.5V, allowing direct interfacing between 1.65V/3.6V logic and 3.3V/5V systems.

Applications

• Bus driving in computing and peripheral systems
• Power down signal isolation
• General purpose logic applications

Procurement Notes

Verify the package code T20 corresponds to the TSSOP-20 form factor when sourcing. Confirm the -13 suffix indicates 13-inch tape and reel packaging. Ensure the specific revision DS35887 Rev. 1-2 matches design requirements. Check RoHS compliance status as defined by the manufacturer's green product definitions.

Selection Notes

Select this component for designs requiring dual 4-bit buffering with independent enable control. The TSSOP-20 package offers a 0.65mm lead pitch suitable for standard surface mount processes. Consider the 1.65V to 3.6V operating range for low-power CMOS applications. Verify thermal resistance parameters if high ambient temperatures are expected.

Part Context

This part belongs to the 74LVC241A series of octal buffers and line drivers. It is designed for low-voltage CMOS technology, offering compatibility with various digital logic families. The TSSOP-20 package provides a compact footprint for space-constrained printed circuit board layouts.

Replacement Considerations

The 74LVC241AQ20-13 serves as a pin-compatible alternative utilizing the QFN-20 package. Both variants share identical electrical characteristics and functionality within the same logic family.
