Texas Instruments SN74LVC2G241YEPR

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 V_CC operation. It delivers ±24-mA output drive at 3.3 V, achieves 4.1-ns max propagation delay, supports 5.5-V tolerant inputs, and features I_off for live insertion and partial-power-down protection. It serves as a redriver in bus interface and memory address driver applications.

For engineers reviewing the SN74LVC2G241 datasheet, SN74LVC2G241 pinout, SN74LVC2G241 application, or SN74LVC2G241 equivalent, key selection criteria include 3-state control logic (active-low 1OE / active-high 2OE), NanoFree™ DSBGA-8 or VSSOP-8 package compatibility, 1.65–5.5-V supply flexibility, overvoltage-tolerant inputs, and I_off-enabled back-drive protection in powered-down systems.

Technical Context

The SN74LVC2G241 implements two independent CMOS buffer gates, each with dedicated output-enable control: Gate 1 uses active-low 1OE, Gate 2 uses active-high 2OE-enabling asymmetric enable sequencing for bus arbitration or staggered driving. Its I_off circuitry actively disables outputs when V_CC = 0 V, blocking current flow between powered and unpowered domains.

It operates across industrial temperature (–40°C to +125°C), supports down-translation (5.5-V inputs to V_CC-level outputs), and meets JESD 78 Class II latch-up (>100 mA) and JESD 22 ESD ratings (±2000-V HBM, ±1000-V CDM). Propagation delay scales inversely with V_CC, reaching 1.0 ns min at 5 V.

FAQ

What is the function of the 1OE and 2OE pins on the SN74LVC2G241YEPR?

The SN74LVC2G241YEPR features two independent output-enable controls: 1OE is active-low (output enabled when low), and 2OE is active-high (output enabled when high). This asymmetric configuration allows precise sequencing-e.g., enabling one buffer while disabling the other without external inverters-critical for bus arbitration and glitch-free state transitions in the SN74LVC2G241YEPR.

Can the SN74LVC2G241YEPR interface a 5-V microcontroller with a 1.8-V FPGA?

Yes. The SN74LVC2G241YEPR accepts inputs up to 5.5 V while operating at V_CC = 1.8 V, enabling direct down-translation without level shifters. Its outputs swing from 0 to 1.8 V, matching the FPGA's input thresholds. This capability is explicitly specified in the SN74LVC2G241YEPR datasheet under "Inputs Accept Voltages to 5.5 V" and "Can Be Used as a Down Translator."

Does the SN74LVC2G241YEPR support hot-plug operation?

Yes. The SN74LVC2G241YEPR integrates I_off circuitry that disables outputs when V_CC = 0 V, limiting back-current to <±10 µA. This protects both the SN74LVC2G241YEPR and connected circuitry during live insertion into powered-backplane systems, satisfying JESD78 Class II latch-up and hot-swap requirements.

What is the maximum output current drive of the SN74LVC2G241YEPR at 3.3 V?

The SN74LVC2G241YEPR delivers ±24 mA per output at V_CC = 3.3 V, as confirmed in the "Features" section and Electrical Characteristics table. This drive strength supports driving 50-Ω transmission lines or multiple CMOS inputs (fanout ≥ 10) while maintaining VOL ≤ 0.55 V and VOH ≥ 2.3 V under load-key for reliable SN74LVC2G241YEPR signal integrity.

Which package options are available for the SN74LVC2G241YEPR, and what are their key mechanical differences?

The SN74LVC2G241YEPR is offered in DSBGA-8 (YZP, 1.91 mm × 0.91 mm), VSSOP-8 (DCU, 2.30 mm × 2.00 mm), and SM8 (DCT, 2.95 mm × 2.80 mm). DSBGA-8 provides the smallest footprint and lowest thermal resistance (R_θJA = 102°C/W); VSSOP-8 balances size and manufacturability; SM8 suits legacy layouts. All share identical pinout and electrical specs.
