Product details
Overview
SN74LVC2G240YEPR 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 VCC operation. It supports 5-V tolerant inputs (up to 5.5 V), delivers ±24-mA output drive at 3.3 V, achieves 4.6-ns max propagation delay at 3.3 V, and features Ioff for live insertion and partial-power-down protection - used in memory address buffering, clock distribution, and bus interface applications.
For engineers reviewing the SN74LVC2G240YEPR datasheet, SN74LVC2G240YEPR pinout, SN74LVC2G240YEPR application, or SN74LVC2G240YEPR equivalent, key selection considerations include its dual-channel 3-state control, voltage translation capability (5.5-V input down to VCC level), low ICC (10 µA max), NanoFree™ DSBGA package footprint, and compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
This device implements two independent noninverting buffers, each with dedicated output-enable (OE) control. Each channel passes A→Y when OE is low; outputs enter high-impedance state when OE is high. The Ioff circuitry actively disables outputs during power-off, preventing back-drive current and enabling hot-plug operation.
Input thresholds are VIL ≤ 0.3×VCC and VIH ≥ 0.7×VCC across 1.65–5.5 V supply, supporting mixed-voltage interfacing. Output VOH/VOL specifications meet LVC logic family standards, with VOL ≤ 0.55 V at 24-mA sink and VOH ≥ 2.3 V at 24-mA source (VCC = 3 V), ensuring robust noise margins in dense PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V systems |
| Max Propagation Delay | 4.6 ns at VCC = 3.3 V - supports high-speed data path timing in memory and clock buffering |
| Output Drive | ±24 mA at VCC = 3.3 V - drives heavy capacitive loads or multiple CMOS inputs without external buffers |
| Ioff Current | ±10 µA max - blocks current flow during power-down, protecting powered subsystems in hot-swap systems |
| Input Voltage Tolerance | Up to 5.5 V - allows direct connection to 5-V logic while operating from lower VCC (e.g., 3.3 V or 1.8 V) |
| Operating Temperature | –40°C to +125°C - qualified for automotive under-hood, industrial control, and telecom infrastructure use |

Pinout & Package
SN74LVC2G240YEPR uses the YZP (DSBGA-8) package: 1.919 mm × 1.858 mm, 0.5-mm pitch, bottom-side ball grid array with pin 1 located at corner A1. This NanoFree™ package eliminates leadframe, using the silicon die as the mechanical structure - reducing parasitic inductance and enabling ultra-compact layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | 1A | Input of first buffer channel - accepts 5.5-V-tolerant signals regardless of VCC level |
| 2 (A2) | 1OE | Active-low enable for first buffer - tie high via pullup for power-up high-Z safety |
| 3 (B1) | 2A | Input of second buffer channel - electrically isolated from 1A, supports independent signal routing |
| 4 (B2) | 2OE | Active-low enable for second buffer - enables per-channel bus arbitration or power gating |
| 5 (C1) | GND | Digital ground reference - must be low-impedance connection to minimize ground bounce (VOLP < 0.8 V) |
| 6 (C2) | 2Y | Output of second buffer - 3-state capable, supports bidirectional bus termination schemes |
| 7 (D1) | 1Y | Output of first buffer - shares no internal nodes with 2Y, allowing differential or isolated load driving |
| 8 (D2) | VCC | Supply voltage input - bypass with 0.1-µF ceramic capacitor near package for stable switching performance |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ DSBGA packaging | Eliminates leadframe parasitics, reduces board area by >50% vs. SSOP/VSSOP, improves thermal resistance (θJA = 102°C/W) |
| 5.5-V tolerant inputs | Enables level-shifting from legacy 5-V peripherals to modern low-voltage controllers without external translators |
| Ioff partial-power-down support | Prevents damaging current flow when VCC = 0 V but inputs remain active - essential for modular backplane designs |
| Low ground bounce (VOLP) | Typical <0.8 V at VCC = 3.3 V ensures signal integrity in high-speed digital interfaces with shared ground planes |
| High noise immunity | VIH/VIL thresholds scale with VCC (0.7×/0.3×), maintaining consistent noise margin across supply voltages |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G241YEPR | Inverting output polarity per channel; identical VCC range, drive strength, and package | Required where signal inversion is needed in address/data paths or clock inversion logic | Select SN74LVC2G241YEPR only when functional inversion is explicitly required - not a drop-in replacement |
| SN74AUP2G240DCUR | Lower ICC (500 nA typical), slower tpd (6.5 ns at 3.3 V), VSSOP-8 package (larger footprint) | Better suited for ultra-low-power battery-operated systems where speed is secondary to quiescent current | Choose SN74AUP2G240DCUR for sub-µA standby power; SN74LVC2G240YEPR preferred for speed-critical or space-constrained designs |
Compared with SN74LVC2G240YEPR, SN74LVC2G241YEPR provides inverted logic functionality in the same NanoFree™ DSBGA package, while SN74AUP2G240DCUR trades speed and size for nanowatt-level static power - making SN74LVC2G240YEPR optimal for high-density, high-speed industrial and automotive signal buffering where board area and timing margin are critical.

FAQ
What is the maximum input voltage rating for SN74LVC2G240YEPR?
The SN74LVC2G240YEPR supports input voltages up to 5.5 V regardless of VCC level - a key feature enabling direct interfacing with 5-V logic families while operating from 1.65-V to 5.5-V supplies. This is confirmed in the Absolute Maximum Ratings table (VI = –0.5 V to 6.5 V) and reinforced in the Features section stating "Inputs Accept Voltages to 5.5 V." This tolerance applies to all input pins (1A, 1OE, 2A, 2OE) of the SN74LVC2G240YEPR.
Does SN74LVC2G240YEPR support hot-swap or live-insertion applications?
Yes, SN74LVC2G240YEPR supports live insertion via its Ioff feature, which disables outputs and limits off-state current to ±10 µA when VCC = 0 V. This prevents current backflow from powered signal lines into an unpowered device - a requirement for hot-pluggable modules in telecom or industrial backplanes. The datasheet explicitly states "Ioff Supports Live Insertion, Partial-Power-Down Mode, and Back-Drive Protection" for the SN74LVC2G240YEPR.
What is the thermal performance of SN74LVC2G240YEPR in its YZP package?
The SN74LVC2G240YEPR in the YZP (DSBGA-8) package has a θJA of 102°C/W, significantly lower than DCT (220°C/W) and DCU (227°C/W) variants. This improved thermal resistance results from the NanoFree™ construction - eliminating the leadframe and using the silicon die as the thermal path. At 10-µA ICC and ±24-mA transient loads, this enables reliable operation in sealed enclosures or high-ambient-temperature industrial environments without additional heatsinking for the SN74LVC2G240YEPR.
Can SN74LVC2G240YEPR be used as a level translator between 5-V and 3.3-V systems?
Yes, SN74LVC2G240YEPR can translate 5-V inputs down to 3.3-V (or lower) logic levels: its inputs accept up to 5.5 V while outputs swing rail-to-rail between GND and the applied VCC (e.g., 3.3 V). This makes it suitable for unidirectional translation from 5-V peripherals to 3.3-V controllers. However, it does not support bidirectional translation or 3.3-V-to-5-V up-translation - that function requires a dedicated bidirectional translator IC, not the SN74LVC2G240YEPR.
What is the recommended power-up sequence for SN74LVC2G240YEPR to ensure high-impedance outputs at startup?
To guarantee high-impedance outputs during power-up, tie both 1OE and 2OE pins to VCC through pullup resistors. The minimum resistor value depends on the driver's current-sinking capability - typically 10 kΩ suffices. This ensures OE remains high (disabling outputs) until the host controller asserts low on OE. The datasheet explicitly states: "To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor" for the SN74LVC2G240YEPR.
