74LVC541AT20-13

Overview

The 74LVC541AT20-13 is an octal buffer and line driver manufactured by Diodes Incorporated, designed for driving bus lines or buffering memory address registers. It operates within a supply voltage range of 1.65V to 3.6V and features inputs tolerant to 5.5V, facilitating mixed-voltage applications. The device provides three-state outputs controlled by two active-low enable inputs (OE1 and OE2). It supports partial power-down operations via I_OFF circuitry to prevent backflow current. Packaged in a TSSOP-20 format with dimensions of 6.4mm x 6.5mm x 1.2mm and a 0.65mm lead pitch.

Feature Summary

• Features inputs and outputs on opposite sides of the package to facilitate printed circuit board layout.
• Includes I_OFF circuitry that disables outputs to prevent damaging current backflow during partial power-down conditions.
• Inputs accept voltages up to 5.5V, allowing compatibility with 3.3V or 5V driven signals in mixed voltage environments.
• All inputs incorporate Schmitt trigger action to accommodate slower input rise and fall times.

Applications

• Bus driving
• Memory address register buffering
• Power down signal isolation

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the 13-inch tape and reel packaging configuration containing 2500 units per reel. Confirm the 'T20' package code matches the required TSSOP-20 footprint and pinout specifications. Ensure compliance requirements such as RoHS and halogen-free status align with project constraints before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring octal buffering with mixed voltage capabilities between 1.65V and 3.6V logic levels. Consider its suitability for applications needing high drive strength of 24mA at 3V. Evaluate the TSSOP-20 package dimensions against available PCB space and thermal management requirements for junction-to-ambient resistance.

Part Context

This part belongs to the 74LVC541A series of octal buffers and line drivers produced by Diodes Incorporated. The series is characterized by low power consumption CMOS technology and robust ESD protection exceeding standard human body and machine model ratings. It serves as a general-purpose logic solution for consumer electronics and computer peripherals.

Replacement Considerations

Check datasheets for other manufacturers offering equivalent 8-bit bus drivers with 3-state outputs and 5.5V tolerant inputs. Verify pin compatibility and electrical characteristics match the original design requirements before substituting.
