Product details

Overview

SN74LVTH241NS from Texas Instruments is an octal noninverting buffer/driver IC designed for 3.3-V V_CC operation with 5-V tolerant inputs and outputs, supporting mixed-mode signal interfacing between 3.3-V logic and legacy 5-V systems. It features dual 4-bit channels, independent output-enable controls (1OE, 2OE), bus-hold circuitry on all data inputs, I_off protection, and operates down to 2.7 V for battery-powered applications.

For engineers reviewing the SN74LVTH241NS datasheet, SN74LVTH241NS pinout, SN74LVTH241NS application, or SN74LVTH241NS equivalent, this device is selected for level-shifting bus interfaces in industrial control backplanes, FPGA I/O expansion, hot-pluggable peripheral modules, and low-voltage embedded subsystems requiring robust input hold and power-up 3-state behavior.

Technical Context

The SN74LVTH241NS implements TTL-compatible output drive (64 mA sink, 32 mA source) while operating from a 2.7–3.6 V supply, enabling direct connection to 5-V buses without external level shifters. Its bus-hold circuitry maintains valid logic states on undriven A-inputs without pullup/pulldown resistors, reducing BOM count and layout complexity.

Power sequencing is supported via I_off and power-up 3-state functionality: outputs enter high-impedance when V_CC < 1.5 V, and OE pins can be externally biased to ensure safe hot-insertion. Propagation delay is 1.1–3.9 ns (t_PLH/t_PHL) at V_CC = 3.3 V with 50-pF load, and ground bounce (V_OLP) remains below 0.8 V under switching conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.7 V to 3.6 V - supports unregulated battery operation and ensures compatibility with standard 3.3-V rail tolerances.
I_OL / I_OH	64 mA sink / 32 mA source - drives heavy capacitive loads and standard TTL inputs without external buffers.
Input Voltage Tolerance	−0.5 V to 7 V - accepts 5-V logic signals directly, eliminating need for discrete level translators.
Bus-Hold Current	±75 µA at V_CC = 3 V - actively holds floating inputs at valid logic levels, removing external biasing components.
t_PLH/t_PHL	1.1–3.9 ns (V_CC = 3.3 V, C_L = 50 pF) - enables high-speed data transfer in 25-MHz+ bus environments.
I_off	±100 µA at V_CC = 0 V - prevents damaging backflow current during hot insertion or partial power-down.
V_OLP	<0.8 V at V_CC = 3.3 V, T_A = 25°C - limits ground bounce noise that could disrupt adjacent digital or analog circuits.

Pinout & Package

SN74LVTH241NS is housed in a 20-pin SOP (Small Outline Package) with 0.65-mm lead pitch, 7.5-mm body width, and 2.0-mm maximum height per JEDEC MO-150. The package is RoHS-compliant, moisture-sensitive level 1, and compatible with standard reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Active-low output enable (separate per 4-bit group)	Controls high-impedance state independently for each half of the octal buffer; tied to GND or controlled by system logic.
1A1–1A4, 2A1–2A4	Data inputs	Eight buffered inputs with integrated bus-hold; no external pull resistors required even when left floating.
1Y1–1Y4, 2Y1–2Y4	Noninverting buffered outputs	Drive 5-V TTL loads directly; support 64-mA sink capability for fanout >10.
V_CC	Positive supply	3.3-V nominal supply; functional down to 2.7 V; must be stabilized with local 0.1-µF ceramic decoupling.
GND	Ground reference	Common return path for all I/O and supply currents; requires low-inductance PCB connection.

Key Features

Feature	Design Value
Mixed-mode voltage interface	3.3-V V_CC with 5-V-tolerant I/O enables seamless interconnection between modern low-voltage logic and legacy 5-V subsystems.
Integrated bus-hold circuitry	Eliminates need for 10-kΩ external pullup/pulldown resistors on all eight data inputs, reducing component count and board area.
Hot-insertion support	I_off and power-up 3-state ensure outputs remain high-Z during power ramp-up/down, preventing bus contention in modular systems.
Low ground bounce	V_OLP < 0.8 V minimizes noise coupling into shared ground planes, critical for mixed-signal or high-density PCBs.
Wide operating temperature	−40°C to +85°C ambient range qualifies SN74LVTH241NS for industrial automation, test equipment, and outdoor electronics.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal buffer applications.

74ALVC244D	Quad-line (not octal); no bus-hold; 1.65–3.6 V; 24 mA drive	Requires two devices to match channel count; lacks hot-insertion support	Select 74ALVC244D only for space-constrained designs accepting doubled footprint and added complexity.

FAQ

What is the minimum V_CC required for functional operation of the SN74LVTH241NS?

The SN74LVTH241NS operates reliably down to 2.7 V per its recommended operating conditions. Below 2.7 V, outputs enter high-impedance regardless of OE state, and logic thresholds become undefined. For battery-powered designs, this allows direct use with partially discharged Li-ion cells without regulation.

Does the SN74LVTH241NS require external pullup resistors on its A-inputs?

No. The SN74LVTH241NS includes active bus-hold circuitry on all eight data inputs, which maintains valid logic states without external pullup or pulldown resistors. Adding external resistors is explicitly discouraged in the datasheet and may degrade noise immunity or increase power consumption.

Can the SN74LVTH241NS safely interface with 5-V microcontrollers while powered from 3.3 V?

Yes. The SN74LVTH241NS accepts input voltages up to 7 V and drives outputs compatible with 5-V TTL logic levels. When powered from 3.3 V, it delivers VOH ≥ 2.4 V and VOL ≤ 0.55 V under full load-meeting standard 5-V TTL VIH/VIL thresholds with margin.

What thermal considerations apply to the SN74LVTH241NS in continuous operation?

The SN74LVTH241NS in NS package has θ_JA = 60°C/W. At 64-mA sink per output and worst-case 0.55-V drop, power dissipation reaches ~350 mW. With 25°C ambient, junction temperature rises ~21°C-well within the −40°C to +125°C rating. Use of 2 oz copper and thermal vias is recommended above 200 mW.

How does the SN74LVTH241NS support hot insertion in modular systems?

The SN74LVTH241NS supports hot insertion via two mechanisms: I_off circuitry disables outputs when V_CC = 0 V, blocking backflow current; and power-up 3-state forces outputs into high-Z during V_CC ramp-up (0–1.5 V). Both features prevent bus contention and protect upstream drivers during live card swaps.
