Nexperia USA Inc. 74LVT2241PW,118

Overview

74LVT2241PW,118 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 mixed-voltage interfacing with 5 V systems.

For engineers reviewing the 74LVT2241PW,118 datasheet, 74LVT2241PW,118 pinout, 74LVT2241PW,118 application, or 74LVT2241PW,118 equivalent, key selection considerations include its dual 4-bit enable control, built-in termination for clean signal integrity on high-speed buses, bus hold functionality for floating input robustness, and overvoltage-tolerant inputs up to 5.5 V.

Technical Context

The device implements two independent 4-bit buffered paths: inputs 1A0–1A3 drive outputs 1Y0–1Y3 under 1OE (active LOW), while 2A0–2A3 drive 2Y0–2Y3 under 2OE (active HIGH). Each output includes a monolithic 30 Ω series resistor to suppress reflections without external components.

Bus hold circuitry maintains valid logic states on unused inputs using ±75–150 μA internal current sources, and IOFF protection ensures low leakage (<100 μA) when VCC = 0 V-enabling live insertion and partial power-down operation in backplane or hot-swap applications.

FAQ

What is the function of the bus hold feature on 74LVT2241PW,118?

The bus hold circuit actively maintains the last-valid logic state on any unused input pin using ±75–150 μA internal current sources. This eliminates the need for external pull-up or pull-down resistors, preventing floating inputs that could cause increased power consumption, logic glitches, or ESD susceptibility - critical in modular or partially populated systems.

Can 74LVT2241PW,118 safely interface with 5 V logic outputs?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, allowing direct connection to 5 V microcontrollers, CPLDs, or legacy peripherals without level shifters. The device's BiCMOS input structure provides robust overvoltage protection while maintaining TTL-compatible thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) at 3.3 V supply.

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

Each output integrates a precise 30 Ω series resistor matching typical PCB trace impedances (50–75 Ω). This damps reflections at the source, reducing overshoot, undershoot, and ringing on traces up to 15 cm - enabling cleaner edges, lower EMI, and reliable operation at >200 MHz without adding discrete resistors or increasing layout complexity.

Is 74LVT2241PW,118 suitable for hot-swap applications?

Yes - it features IOFF circuitry that disables output leakage when VCC = 0 V, and bus hold maintains defined input states during insertion. Combined with live-insertion qualification and ±12 mA drive, it supports safe hot-plug operation in modular backplanes, test equipment, and field-replaceable I/O modules without disrupting system power or logic states.
