Texas Instruments SN74LVTH241PWR

Overview

SN74LVTH241PWR from Texas Instruments is an octal noninverting buffer/driver with dual 4-bit channels, designed for 3.3-V V_CC operation while supporting 5-V TTL-level inputs and outputs. It features bus-hold circuitry on all data inputs, I_off and power-up 3-state for hot insertion, and operates down to 2.7 V for battery-powered systems - used in mixed-voltage backplane interface and legacy bus bridging applications.

For engineers reviewing the SN74LVTH241PWR datasheet, SN74LVTH241PWR pinout, SN74LVTH241PWR application, or SN74LVTH241PWR equivalent, key selection criteria include its 20-pin TSSOP package, ±100 µA I_off at V_CC = 0 V, 64 mA I_OL drive strength, bus-hold input stabilization, and guaranteed 2.7–3.6 V supply range with 5-V tolerant inputs.

Technical Context

This device implements two independent 4-bit noninverting buffer sections (1A→1Y and 2A→2Y), each controlled by separate output-enable inputs (1OE low or 2OE high enables respective outputs). Its bus-hold circuitry actively maintains valid logic states on undriven inputs without external resistors, eliminating pullup/pulldown requirements.

The SN74LVTH241PWR integrates I_off protection and power-up 3-state logic to ensure high-impedance outputs during power transitions - critical for hot-swap compliance. Absolute maximum ratings allow 5.5-V input voltage tolerance and −0.5 V to 4.6 V V_CC, enabling robust interfacing between 3.3-V logic and 5-V legacy systems.

FAQ

What is the operating voltage range for SN74LVTH241PWR?

The SN74LVTH241PWR operates over a V_CC range of 2.7 V to 3.6 V, with input voltage tolerance from −0.5 V to 5.5 V. This allows direct interfacing with 5-V TTL logic while running from a 3.3-V supply - essential for mixed-voltage board designs. The device remains functional across the full industrial temperature range of −40°C to 85°C.

Does SN74LVTH241PWR require external pullup resistors on its inputs?

No, SN74LVTH241PWR does not require external pullup or pulldown resistors because it integrates active bus-hold circuitry on all data inputs (1A1–1A4 and 2A1–2A4). This circuitry maintains the last valid logic state on undriven or floating inputs, eliminating BOM cost and layout complexity - a key differentiator from standard LVC or AHCT buffers.

Can SN74LVTH241PWR be used in hot-swap applications?

Yes, SN74LVTH241PWR supports hot insertion via integrated I_off protection and power-up 3-state logic. When V_CC is 0 V, I_off limits current to ±100 µA, preventing backflow. During power-up/down, outputs remain in high-impedance until V_CC stabilizes above 1.5 V - ensuring no bus contention or damage during live module replacement.

What is the maximum output drive strength of SN74LVTH241PWR?

SN74LVTH241PWR delivers up to 64 mA of low-level output current (I_OL) and 32 mA of high-level output current (I_OH) per channel under recommended conditions. This enables direct driving of multiple TTL loads or moderate-capacitance buses without external amplification - verified at V_CC = 3.3 V and TA = 25°C.

What package type is SN74LVTH241PWR supplied in?

SN74LVTH241PWR is supplied in a 20-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm lead pitch, body dimensions of 6.6 mm × 4.5 mm × 1.2 mm, and NiPdAu lead finish. It is RoHS-compliant, MSL Level-1 rated, and shipped in tape-and-reel format (2000 units per reel) - optimized for automated SMT assembly and space-constrained PCBs.
