SN74LVTH541DB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH541DB is an octal buffer and driver from the LVTH logic family, manufactured by Texas Instruments. It operates at a supply voltage (VCC) of 2.7 V to 3.6 V with inputs compatible with TTL levels up to 5.5 V. The device features 8 non-inverting channels with 3-state outputs controlled by two active-low enable inputs (OE1, OE2). Packaged in a 20-pin SSOP, it supports mixed-mode signal operation, allowing 5-V input and output voltages with 3.3-V VCC. Key electrical characteristics include a typical propagation delay of 2.4 ns at 3.3 V, low static current, and bus-hold circuitry on data inputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation for interfacing 5-V systems with 3.3-V environments
• Features dual active-low output enables for flexible 3-state control
• Includes active bus-hold circuitry to maintain valid logic states on undriven inputs
• Provides Ioff and power-up 3-state support to prevent backflow during hot insertion

Buffers, Drivers, Receivers, Transceivers Applications

• Driving bus lines in digital systems
• Buffering memory address registers
• Mixed-signal interface circuits between different voltage domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the DB suffix denotes the SSOP-20 form factor. Confirm RoHS compliance status and lead finish details via the latest TI Package Option Addendum, as manufacturing parameters may update. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration for your assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with 3-state capability is required for 3.3-V logic systems interfacing with 5-V signals. The dual enable inputs offer greater control flexibility compared to single-enable devices. Consider the SSOP package dimensions for PCB layout constraints and verify that the operating temperature range meets the application's environmental requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVTH541 series, which includes variants in SOIC, SOP, and TSSOP packages. It is part of Texas Instruments' LVTH line designed for low-voltage applications while maintaining compatibility with legacy 5-V logic standards. The series is widely used in embedded systems requiring high-density buffering and level shifting.
