Texas Instruments 74LVC2G241DCUTG4

Overview

74LVC2G241DCUTG4 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, and supports 5.5-V tolerant inputs - enabling level translation from 5-V logic down to lower VCC rails. It serves as a redriver in memory-address and clock distribution paths within compact consumer electronics.

For engineers reviewing the 74LVC2G241DCUTG4 datasheet, 74LVC2G241DCUTG4 pinout, 74LVC2G241DCUTG4 application, or 74LVC2G241DCUTG4 equivalent, key selection criteria include Ioff-enabled partial-power-down capability, NanoFree™ VSSOP-8 package footprint (2.30 mm × 2.00 mm), 3.3-V/5-V mixed-signal interface compatibility, and verified 125°C operational rating per TI SCES210P Rev P.

Technical Context

The 74LVC2G241DCUTG4 implements two independent CMOS buffer gates, each with active-low (1OE) and active-high (2OE) output-enable controls - allowing asymmetric enable sequencing for bus arbitration. Its Ioff circuitry disables outputs during power-down, blocking back-drive current and supporting live insertion in hot-swap systems.

It features overvoltage-tolerant inputs (up to 5.5 V regardless of VCC), rail-to-rail output swing, and low ground bounce (VOLP < 0.8 V) and undershoot (VOHV > 2 V) at 3.3 V - critical for signal integrity in high-speed digital interfaces operating up to 100 MHz.

FAQ

What is the maximum operating temperature for the 74LVC2G241DCUTG4?

The 74LVC2G241DCUTG4 is fully specified from –40°C to +125°C ambient temperature per TI SCES210P Rev P. This extended range qualifies it for under-hood automotive applications and industrial control environments where thermal margins are critical. All electrical parameters - including tpd, VOH/VOL, and Ioff - are guaranteed across this full range.

Does the 74LVC2G241DCUTG4 support 5-V input signals when powered from a 3.3-V supply?

Yes, the 74LVC2G241DCUTG4 supports input voltages up to 5.5 V regardless of VCC level. When powered from 3.3 V, its inputs remain 5-V tolerant - enabling direct connection to legacy 5-V peripherals without external level shifters. This behavior is explicitly confirmed in the "Recommended Operating Conditions" table of the official datasheet.

What is the purpose of the dual output-enable pins (1OE and 2OE) on the 74LVC2G241DCUTG4?

The 74LVC2G241DCUTG4 uses 1OE (active-low) and 2OE (active-high) to allow independent, asymmetric control of its two buffer outputs. This enables precise bus arbitration - for example, holding one output enabled while disabling the other during data handshaking - a capability not offered by single-OE alternatives like the 74LVC2G125. The functional tables in Section 8.4 confirm this behavior.

Is the 74LVC2G241DCUTG4 pin-compatible with other VSSOP-8 logic devices?

The 74LVC2G241DCUTG4 uses the industry-standard VSSOP-8 (DCU) footprint (2.30 mm × 2.00 mm, 0.5-mm pitch) and shares identical pin numbering and functions with TI's SN74LVC2G125DCUT and SN74LVC2G126DCUT. However, OE polarity differs: 74LVC2G241DCUTG4 has mixed OE logic (1OE active-low, 2OE active-high), whereas others use uniform active-high OE.

How does the Ioff feature of the 74LVC2G241DCUTG4 improve system reliability?

The Ioff feature disables all outputs when VCC = 0 V, limiting off-state leakage to ±10 µA. This prevents damaging back-current flow from live system buses into a powered-down section - a critical safeguard in hot-swap architectures and multi-rail systems. TI validates this behavior per JESD78 Class II latch-up testing, ensuring robustness during power sequencing events.
