Product details

Overview

74LVT2241D,112 from Nexperia is a 3.3 V octal 3-state buffer/line driver with integrated 30 Ω series output termination resistors, dual independent output enables (1OE active LOW, 2OE active HIGH), bus hold inputs eliminating external pull-ups, and ±12 mA drive capability. It operates from 2.7 V to 3.6 V and supports 5 V-tolerant inputs for mixed-voltage system interfacing in high-speed digital backplanes.

For engineers reviewing the 74LVT2241D,112 datasheet, 74LVT2241D,112 pinout, 74LVT2241D,112 application, or 74LVT2241D,112 equivalent, key selection criteria include its dual 4-bit enable control, on-die 30 Ω series termination, bus hold functionality, -40 °C to +85 °C industrial temperature range, and SO20 (SOT163-1) package compatibility with legacy 74-series footprints.

Technical Context

The device implements two independent 4-bit buffered paths: inputs 1A0–1A3 drive outputs 1Y0–1Y3 under control of active-LOW 1OE; inputs 2A0–2A3 drive outputs 2Y0–2Y3 under control of active-HIGH 2OE. Each output integrates a 30 Ω series resistor to suppress transmission-line reflections without external components.

Bus hold circuitry maintains valid logic states on unused inputs at VI = 0.8 V (LOW) or 2.0 V (HIGH), eliminating external biasing. IOFF protection ensures low leakage (<100 μA) during partial power-down, and overvoltage-tolerant inputs withstand up to 5.5 V regardless of VCC state.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	2.7 V to 3.6 V - Enables direct interface with 3.3 V LVTTL and mixed 5 V/3.3 V systems.
Output drive	±12 mA - Sustains signal integrity driving 50 Ω transmission lines or multiple TTL loads.
Propagation delay	1.0–4.3 ns (VCC = 3.3 V) - Supports >200 MHz data rates in point-to-point or stubbed bus topologies.
Input voltage tolerance	Up to 5.5 V - Allows safe connection to 5 V buses without level shifters.
Termination resistance	30 Ω series per output - Matches typical PCB trace impedance to minimize overshoot/ringing.
Operating temperature	-40 °C to +85 °C - Qualified for industrial-grade embedded control and communications equipment.
Bus hold current	±75 μA to ±150 μA - Actively retains input state without external resistors, reducing BOM count.

Pinout & Package

74LVT2241D,112 is housed in a plastic small outline package (SO20, SOT163-1) with 20 leads and 7.5 mm body width. Pin 1 is index-marked; lead pitch is 1.27 mm. The package is RoHS-compliant and rated for reflow soldering per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1OE	Active-LOW output enable	Controls high-impedance state for outputs 1Y0–1Y3; ties to GND or logic LOW to activate.
2OE	Active-HIGH output enable	Controls high-impedance state for outputs 2Y0–2Y3; ties to VCC or logic HIGH to activate.
1A0–1A3, 2A0–2A3	Data inputs	Eight total inputs grouped into two 4-bit banks; each features bus hold for floating-input immunity.
1Y0–1Y3, 2Y0–2Y3	3-state outputs	Eight buffered outputs, each with integrated 30 Ω series resistor; no external termination required.
VCC (Pin 20)	Power supply	3.3 V nominal supply; accepts 2.7–3.6 V range; decoupling capacitor required near pin.
GND (Pin 10)	Ground reference	Primary return path for all I/O and supply currents; must be low-inductance connection.

Key Features

Feature	Design Value
Dual independent 4-bit enables	Allows selective activation of two separate 4-bit data paths without gating logic or additional control lines.
Integrated 30 Ω series termination	Eliminates need for eight discrete 30 Ω resistors, saving board space and improving signal fidelity on FR-4 traces.
Bus hold inputs	Maintains defined logic levels on unconnected inputs, preventing metastability and EMI in sparse-bus configurations.
5.5 V overvoltage-tolerant inputs	Enables direct connection to 5 V microcontrollers or FPGAs without level translators in mixed-supply systems.
IOFF partial power-down	Prevents current backflow when VCC = 0 V but I/O pins are biased, supporting hot-swap and power-gating designs.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVT2241PW,118	TSSOP20 (SOT360-1) package; 4.4 mm body width; identical electrical specs.	Better thermal performance and higher density mounting; requires finer-pitch reflow profile.	Select for space-constrained boards where SO20 footprint is unavailable.
SN74LVC244APWR	No integrated termination; 24 mA drive; 1.65–3.6 V supply; no bus hold.	Lacks 30 Ω series resistors and bus hold; requires external pull-ups and termination for same use cases.	Select only if higher drive strength is needed and board-level termination is acceptable.

Compared with 74LVT2241PW,118, the 74LVT2241D,112 offers identical functionality in a wider SO20 package suited for manual assembly and legacy tooling; compared with SN74LVC244APWR, it delivers built-in termination and bus hold-reducing design effort and component count for noise-sensitive backplane interfaces.

FAQ

What is the function of the two output enables (1OE and 2OE) on the 74LVT2241D,112?

1OE is an active-LOW enable controlling outputs 1Y0–1Y3; 2OE is an active-HIGH enable controlling outputs 2Y0–2Y3. This dual-enable architecture allows independent 4-bit channel control without external logic, supporting flexible bus partitioning and reduced control pin count in FPGA or microcontroller interfaces.

Can the 74LVT2241D,112 safely interface with 5 V logic while powered at 3.3 V?

Yes-the inputs tolerate up to 5.5 V regardless of VCC level, and outputs are 5 V-tolerant when in high-impedance or driven LOW. When driving HIGH, VOH is referenced to VCC (≥2.0 V at 3.3 V), meeting TTL input thresholds. No level-shifting circuitry is required for bidirectional 3.3 V ↔ 5 V signal translation.

How does the integrated 30 Ω series termination improve signal integrity?

Each output includes a monolithic 30 Ω resistor in series with the driver, matching typical PCB microstrip impedance (40–70 Ω) to suppress reflections at the source end. This eliminates ringing and overshoot on traces up to 15 cm, reduces EMI, and avoids the placement errors and parasitics associated with discrete termination resistors.

Does the 74LVT2241D,112 require external pull-up resistors on unused inputs?

No-bus hold circuitry actively maintains the last-valid logic state on all data inputs (1A0–1A3, 2A0–2A3) with ±75 μA to ±150 μA holding current. This eliminates external pull-ups, reduces BOM cost, prevents floating-node noise coupling, and simplifies layout in sparsely populated bus architectures.
