Texas Instruments 74LVC2G241DCTRE4

Overview

74LVC2G241DCTRE4 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, and supports 5.5-V tolerant inputs - enabling level translation from higher-voltage sources into lower-VCC systems. It serves as a redriver in memory-address, clock, and bus-oriented signal paths in compact consumer electronics.

For engineers reviewing the 74LVC2G241DCTRE4 datasheet, 74LVC2G241DCTRE4 pinout, 74LVC2G241DCTRE4 application, or 74LVC2G241DCTRE4 equivalent, key selection criteria include its Ioff-enabled partial-power-down capability, NanoFree™ SM8 package (2.95 mm × 2.80 mm), dual independent OE control (1OE active-low, 2OE active-high), and guaranteed 3-state isolation under power sequencing conditions.

Technical Context

The 74LVC2G241DCTRE4 implements two independent noninverting buffers, each with dedicated output-enable logic: Gate 1 activates when 1OE is low and 2OE is high; Gate 2 activates when 2OE is low and 1OE is high. Its Ioff circuitry disables both outputs during power-down, blocking backflow current up to ±10 µA at 5.5 V.

It operates across –40°C to 125°C with rail-to-rail output swing (VOL ≤ 0.45 V at 1.65 V, VOH ≥ VCC – 0.1 V), input overvoltage tolerance to 5.5 V regardless of VCC, and ESD robustness per JESD22 (±2000-V HBM, ±1000-V CDM). The device is not a bus transceiver but a unidirectional driver optimized for density-critical address/data buffering.

Key Specifications

Pinout & Package

FAQ

What is the function of the 74LVC2G241DCTRE4?

The 74LVC2G241DCTRE4 is a dual 1-bit noninverting buffer/driver with independent 3-state outputs. It functions as a redriver for memory address, clock, and bus signals, supporting 1.65-V to 5.5-V operation. Each channel has dedicated output-enable control: 1OE is active-low and 2OE is active-high. The 74LVC2G241DCTRE4 does not perform logic inversion or level translation beyond its inherent 5.5-V input tolerance.

Does the 74LVC2G241DCTRE4 support partial-power-down operation?

Yes, the 74LVC2G241DCTRE4 fully supports partial-power-down via its Ioff circuitry. When VCC = 0 V, the Ioff feature limits current flow through the device to ±10 µA maximum, preventing damaging backdrive current from live signal lines into unpowered sections. This capability is verified per JEDEC JESD78 Class II latch-up standards and enables safe hot-swap and modular power sequencing.

What is the recommended power supply decoupling for the 74LVC2G241DCTRE4?

A 0.1-µF ceramic capacitor placed as close as possible to the VCC pin (Pin 8) and GND (Pin 4) is mandatory for stable operation of the 74LVC2G241DCTRE4. TI recommends using X7R or better dielectric with low ESL. For systems with multiple 74LVC2G241DCTRE4 devices or high-frequency switching, paralleling a 1-µF capacitor improves broadband noise suppression. No separate decoupling is needed for OE or A inputs.

Can the 74LVC2G241DCTRE4 be used as a level translator?

The 74LVC2G241DCTRE4 supports down-translation: its inputs accept voltages up to 5.5 V regardless of VCC, allowing connection to 5-V sources while operating from 1.8-V or 3.3-V supplies. However, it does not translate upward - outputs swing only between GND and VCC. For bidirectional or up-translation, a dedicated level shifter such as TXS0102 is required. The 74LVC2G241DCTRE4 is not a bus transceiver.

What is the thermal performance of the 74LVC2G241DCTRE4 in its SM8 package?

The 74LVC2G241DCTRE4 in the SM8 (DCT) package has a junction-to-ambient thermal resistance (RθJA) of 220°C/W. At maximum rated output current (±24 mA) and 3.3-V supply, power dissipation remains below 100 mW under typical conditions, resulting in minimal temperature rise. For continuous high-current operation above 85°C ambient, derating per TI's thermal guidelines is advised - no heatsink is required for standard use cases.
