Nexperia USA Inc. 74LVT2241PW,112

Overview

74LVT2241PW,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 backplane interfacing in high-speed digital systems.

For engineers reviewing the 74LVT2241PW,112 datasheet, 74LVT2241PW,112 pinout, 74LVT2241PW,112 application, or 74LVT2241PW,112 equivalent, key selection criteria include its dual 4-bit enable architecture, on-die 30 Ω series termination, bus hold functionality, -40 °C to +85 °C industrial temperature range, and TSSOP20 package compatibility with high-density PCB layouts.

Technical Context

The device implements two independent 4-bit buffered paths (1A0–1A3 → 1Y0–1Y3 and 2A0–2A3 → 2Y0–2Y3), each controlled by separate output enables: 1OE (active LOW) and 2OE (active HIGH). This allows selective tri-state control of either group without affecting the other.

Each output integrates a 30 Ω series resistor to match transmission line impedance and suppress reflections, enabling direct connection to unterminated 50 Ω traces without external components. Bus hold circuitry maintains valid logic states on unused inputs at ±75 μA hold current, preventing floating nodes.

FAQ

What is the function of the two output enables (1OE and 2OE) on the 74LVT2241PW,112?

1OE (pin 1) is active LOW and controls outputs 1Y0–1Y3 (pins 12,14,16,18); 2OE (pin 19) is active HIGH and controls outputs 2Y0–2Y3 (pins 3,5,7,9). This dual-enable architecture allows independent tri-state control of two 4-bit groups, enabling flexible bus segmentation and contention avoidance in multi-controller systems without external logic.

Can the 74LVT2241PW,112 safely interface with 5 V logic while operating at 3.3 V supply?

Yes - all inputs (1A0–1A3, 2A0–2A3, 1OE, 2OE) tolerate up to 5.5 V regardless of VCC level, and outputs are 5 V compatible when driven into 5 V-biased buses. The device includes overvoltage protection and IOFF circuitry, ensuring no current flows into VCC when interfacing with higher-voltage systems, making it ideal for mixed-supply backplanes.

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

Each output includes a monolithic 30 Ω series resistor that matches typical PCB trace impedances (e.g., 50–75 Ω) when combined with load capacitance. This damps reflections at the source, reducing overshoot, undershoot, and ringing on high-speed digital lines - eliminating the need for eight discrete 30 Ω resistors and associated layout complexity while maintaining <5 ns edge fidelity.

Does the 74LVT2241PW,112 require external pull-up resistors on unused inputs?

No - the device features built-in bus hold circuitry on all data inputs (1A0–1A3, 2A0–2A3), which actively maintains the last-valid logic state with ±75 μA to ±150 μA hold current. This eliminates floating inputs and removes the need for external pull-up or pull-down resistors, simplifying design and reducing BOM count in partially populated I/O subsystems.
