Product details

Overview

SN74LVTH241DWRG4 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 and 5-V systems. It features dual 4-bit channels with independent output-enable (1OE, 2OE), bus-hold circuitry on all data inputs, I_off protection, and hot-insertion support. Used in backplane interface, legacy bus bridging, and industrial control I/O expansion.

For engineers reviewing the SN74LVTH241DWRG4 datasheet, SN74LVTH241DWRG4 pinout, SN74LVTH241DWRG4 application, or SN74LVTH241DWRG4 equivalent, this page delivers verified electrical specs, SOIC-20 package details, bus-hold behavior, hot-swap timing, and real-world interface use cases - all confirmed from TI's official SCAS352K datasheet and packaging addendum.

Technical Context

The SN74LVTH241DWRG4 implements TTL-compatible input thresholds (V_IL = 0.8 V, V_VIH = 2.0 V) while operating from a 2.7–3.6-V supply, enabling direct connection to 5-V logic without level shifters. Its bus-hold circuitry provides ±75 µA dynamic hold current at V_CC = 3 V, eliminating external pull resistors on unused inputs.

Power-up 3-state and I_off functionality ensure high-impedance outputs during power transitions and prevent backflow current when V_CC = 0. Output drive capability is rated at I_OL = 64 mA and I_OHL = −32 mA per channel at V_CC = 3 V, with propagation delays as low as 1.1 ns (t_PLH) under CL = 50 pF.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.7 V to 3.6 V - supports unregulated battery operation down to 2.7 V without functional degradation.
Input Voltage Tolerance	−0.5 V to 7 V - enables direct 5-V signal interfacing with no external clamping required.
I_OL / I_OH	64 mA / −32 mA - sufficient to drive standard TTL loads or multiple CMOS inputs without fanout limitation.
t_PLH / t_PHL	1.1 ns / 1.2 ns (min, V_CC = 3.3 V) - ensures sub-nanosecond timing margin for high-speed bus buffering.
Bus-Hold Current	±75 µA at V_CC = 3 V - actively maintains valid logic state on floating inputs, removing need for external biasing.
I_off	±100 µA (V_CC = 0) - blocks damaging current flow during hot insertion or partial power-down.
ESD Rating	2000-V HBM, 200-V MM - exceeds JEDEC JESD22-A114/A115, suitable for handling in non-EPA environments.

Pinout & Package

SN74LVTH241DWRG4 is housed in a 20-pin SOIC (DW) package, 7.5 mm × 12.8 mm body size, 1.27 mm lead pitch, 2.65 mm max height, RoHS-compliant NIPDAU finish, MSL Level-1 (260°C peak reflow).

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Active-Low Output Enable Controls	1OE enables Group 1 (Y1–Y4); 2OE enables Group 2 (Y1–Y4); both must be asserted for full 8-bit output drive.
1A1–1A4, 2A1–2A4	Data Inputs	Eight TTL-compatible inputs with integrated bus-hold; no external pullup/pulldown needed for undriven lines.
1Y1–1Y4, 2Y1–2Y4	Noninverting Outputs	Drive 5-V logic directly; output impedance and current rating support fanout to ≥10 TTL loads.
GND (Pin 10), V_CC (Pin 11)	Power Terminals	Dual dedicated power pins minimize ground bounce; typical V_OLP < 0.8 V at V_CC = 3.3 V, TA = 25°C.

Key Features

Feature	Design Value
Mixed-mode voltage interface	Operates at 3.3-V V_CC while accepting and driving 5-V signals - eliminates discrete level translators in mixed-voltage systems.
Integrated bus-hold	Holds unused A-inputs at valid logic levels using internal feedback; prevents metastability and EMI from floating nodes.
Hot-insertion support	I_off + power-up 3-state guarantee safe insertion into live backplanes without disrupting system operation or damaging downstream components.
Latch-up immunity	Exceeds 500 mA per JESD17 - ensures robustness in noisy industrial environments with transient coupling or ground shifts.
Low ground bounce	V_OLP < 0.8 V at V_CC = 3.3 V - reduces noise coupling into adjacent signal paths and improves signal integrity on dense PCBs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC244APWR	No bus-hold; lower drive (24 mA); 1.65–3.6-V V_CC; no 5-V tolerant inputs.	Requires external pull resistors; unsuitable for floating-bus or hot-swap scenarios.	Select only if cost-sensitive and all inputs are actively driven; verify 5-V compatibility via external clamping diodes.
SN74ALVCH16244DGGR	16-bit, 3.3-V-only I/O; no 5-V tolerance; higher speed (t_PD = 2.5 ns); separate V_CCA/V_CCB rails.	Designed for point-to-point high-speed buses, not mixed-voltage backplanes.	Choose for 16-bit parallel links with strict timing closure; avoid where 5-V signal presence is guaranteed.

Compared with SN74LVC244APWR and SN74ALVCH16244DGGR, the SN74LVTH241DWRG4 uniquely combines 5-V input tolerance, integrated bus-hold, and hot-insertion safety - making it irreplaceable in legacy-system upgrades where signal integrity and plug compatibility are non-negotiable.

FAQ

What is the maximum input voltage the SN74LVTH241DWRG4 can tolerate?

The SN74LVTH241DWRG4 accepts input voltages from −0.5 V to 7 V, enabling direct connection to 5-V logic without external clamping. This 5-V tolerance is maintained across the full operating temperature range (−40°C to 85°C) and does not require V_CC to be powered for safe input exposure.

Does the SN74LVTH241DWRG4 require external pull-up or pull-down resistors on its inputs?

No. The SN74LVTH241DWRG4 integrates active bus-hold circuitry on all eight data inputs (1A1–1A4, 2A1–2A4), providing ±75 µA hold current at V_CC = 3 V. This eliminates the need for external resistors and prevents floating-input-induced noise or metastability.

Can the SN74LVTH241DWRG4 be used in hot-insertion applications?

Yes. The SN74LVTH241DWRG4 supports hot insertion via two complementary features: I_off circuitry disables outputs when V_CC = 0, preventing backflow current, and power-up 3-state forces outputs into high-impedance during power ramp-up/down - both confirmed per TI's SCAS352K datasheet.

What is the output drive capability of the SN74LVTH241DWRG4 at 3.3-V supply?

At V_CC = 3.3 V, the SN74LVTH241DWRG4 delivers I_OL = 64 mA (low-state) and I_OH = −32 mA (high-state) per output, meeting or exceeding standard TTL load requirements. These values are specified over temperature and ensure reliable fanout to ≥10 TTL inputs.

What package type and dimensions does the SN74LVTH241DWRG4 use?

The SN74LVTH241DWRG4 uses a 20-pin SOIC (DW) package: 7.5 mm × 12.8 mm body, 1.27 mm lead pitch, 2.65 mm max height, RoHS-compliant NIPDAU finish, and MSL Level-1 rating. Pin 1 index area and land pattern match JEDEC MS-013 standards.
