Nexperia USA Inc. 74LVT2241D,118

Overview

74LVT2241D,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 across 2.7 V to 3.6 V supply and supports 5 V-tolerant inputs for mixed-voltage system interfacing in high-speed digital backplanes.

For engineers reviewing the 74LVT2241D,118 datasheet, 74LVT2241D,118 pinout, 74LVT2241D,118 application, or 74LVT2241D,118 equivalent, key selection criteria include its dual 4-bit enable control architecture, built-in 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: Group 1 (1A0–1A3 → 1Y0–1Y3, controlled by 1OE) and Group 2 (2A0–2A3 → 2Y0–2Y3, controlled by 2OE). Each output integrates a 30 Ω series resistor to suppress transmission line reflections without requiring external components.

Bus hold circuitry maintains stable logic states on unused inputs at VI ≤ 0.8 V or VI ≥ 2.0 V, drawing only ±75–150 μA. IOFF protection ensures low leakage (< ±100 μA) during partial power-down, while overvoltage tolerance up to 5.5 V on all inputs enables safe interfacing with 5 V systems.

FAQ

Can 74LVT2241D,118 be used with a 5 V supply?

No. The absolute maximum VCC is +4.6 V, and recommended operation is strictly 2.7 V to 3.6 V. However, all inputs tolerate up to 5.5 V, enabling safe connection to 5 V signal sources while powered from 3.3 V. Exceeding 3.6 V on VCC risks permanent damage and violates JEDEC JESD8C compliance.

What is the purpose of the two separate output enables (1OE and 2OE)?

1OE (active LOW) and 2OE (active HIGH) independently control two groups of four outputs: 1Y0–1Y3 and 2Y0–2Y3. This allows selective tri-stating of subsets of the octal bus-for example, isolating address lines while keeping data lines active-enabling flexible bus arbitration and reduced contention in multi-master systems.

How does the bus hold feature affect system design?

The bus hold circuit actively maintains the last-valid logic state on any input pin with ±75–150 μA current, eliminating the need for external 10 kΩ pull-up or pull-down resistors. This reduces BOM cost, saves PCB space, and prevents undefined states during power-up, hot-swap, or unpopulated connector scenarios-critical in modular industrial hardware.

Is the 30 Ω series termination matched to standard PCB trace impedance?

Yes. The 30 Ω on-die series resistor is designed to combine with typical 50–75 Ω PCB trace impedances to achieve near-perfect source termination, minimizing reflections and ringing. When driving a 50 Ω load, total source impedance becomes ~80 Ω; for 75 Ω loads, it yields ~105 Ω-both within acceptable mismatch tolerances (<15 %) for most backplane applications.
