Texas Instruments SN74LVC2G241YEAR

Overview

SN74LVC2G241 from Texas Instruments is a dual 1-bit noninverting buffer/driver with independent 3-state outputs, designed for 1.65-V to 5.5-V operation. It delivers ±24-mA output drive at 3.3 V, achieves 4.1-ns max propagation delay at 3.3 V, supports 5.5-V tolerant inputs, and features Ioff for live insertion and partial-power-down protection - enabling use in memory-address buffering, clock distribution, and bus interface redriving applications.

For engineers reviewing the SN74LVC2G241 datasheet, SN74LVC2G241 pinout, SN74LVC2G241 application, or SN74LVC2G241 equivalent, key selection considerations include its dual independent 3-state control (1OE active-low, 2OE active-high), NanoFree™ DSBGA/SSOP/VSSOP package options, 1.65–5.5-V supply range, overvoltage-tolerant inputs, and Ioff-enabled back-drive protection in powered-down systems.

Technical Context

The SN74LVC2G241 implements two independent CMOS buffer channels, each with dedicated output-enable logic: Gate 1 enables on low at 1OE, Gate 2 enables on high at 2OE. Its design targets high-density bus interfacing where asymmetric enable polarity simplifies control logic in multi-device configurations.

It uses TI's advanced LVC process for rail-to-rail output swing, sub-10 ns switching across 1.8–5 V supplies, and robust ESD resilience (±2000-V HBM). The Ioff specification ensures <10 µA off-state leakage when VCC = 0 V and inputs/outputs biased up to 5.5 V - critical for hot-swap and mixed-voltage system partitioning.

FAQ

What is the function of the 1OE and 2OE pins on the SN74LVC2G241?

The SN74LVC2G241 features two independent output-enable controls: 1OE is active-low (Gate 1 enabled when low), and 2OE is active-high (Gate 2 enabled when high). This asymmetric polarity allows flexible timing control - for example, enabling one buffer while disabling the other without external inversion logic. Both pins must be actively driven; floating OE pins may cause undefined output states.

Can the SN74LVC2G241 operate with a 1.8-V supply and interface with 5-V signals?

Yes. The SN74LVC2G241 supports VCC from 1.65 V to 5.5 V and accepts input voltages up to 5.5 V regardless of supply voltage. When operated at 1.8 V, it safely translates 5-V inputs down to 1.8-V logic levels - making the SN74LVC2G241 ideal for bridging legacy 5-V peripherals to modern low-voltage processors.

Does the SN74LVC2G241 support hot-swap or partial-power-down operation?

Yes. The SN74LVC2G241 includes Ioff circuitry that limits off-state current to <10 µA when VCC = 0 V and any input or output is biased to 5.5 V. This feature protects against back-current flow during hot-insertion or partial-power-down scenarios - a key requirement for modular systems using the SN74LVC2G241 in backplane or card-edge interfaces.

What is the maximum output drive capability of the SN74LVC2G241 at 3.3 V?

At VCC = 3.3 V, the SN74LVC2G241 delivers ±24 mA per output - sufficient to drive standard 50-Ω transmission lines or up to 10 LS-TTL loads. This high drive strength enables clean signal integrity in redriving applications such as memory address buses or clock distribution networks without additional buffering stages.

Which package options are available for the SN74LVC2G241, and what are their key mechanical differences?

The SN74LVC2G241 is offered in three packages: SM8 (DCT, 2.95 mm × 2.80 mm), VSSOP (DCU, 2.30 mm × 2.00 mm), and DSBGA (YZP, 1.91 mm × 0.91 mm). The DSBGA variant uses NanoFree™ technology - eliminating leadframe and mold compound - resulting in the smallest footprint and lowest thermal resistance (102°C/W), while SM8 offers highest manufacturability in standard SMT lines.
