Product details
Overview
SN74LVC2G240YZAR 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 features ±24-mA output drive at 3.3 V, 4.6-ns max propagation delay at 3.3 V, and Ioff support for live insertion and partial-power-down. It serves in bus-oriented receivers/transmitters and memory address drivers where level translation and low-power 3-state control are critical.
For engineers reviewing the SN74LVC2G240YZAR datasheet, SN74LVC2G240YZAR pinout, SN74LVC2G240YZAR application, or SN74LVC2G240YZAR equivalent, key selection criteria include VCC range compatibility (1.65–5.5 V), 3-state enable timing (ten/tdis), output drive strength (±24 mA @ 3.3 V), ground bounce (VOLP < 0.8 V), and NanoFree™ DSBGA package constraints.
Technical Context
This device implements two independent noninverting buffer channels, each with dedicated active-low output-enable (OE) control. Each channel passes A→Y when OE is low and enters high-impedance state when OE is high. The Ioff circuitry disables outputs during power-down, preventing back-drive current even when inputs exceed VCC.
It supports down-translation: inputs tolerate up to 5.5 V regardless of VCC (e.g., 5.5-V signals into 1.8-V system), enabling interoperability across voltage domains. Built-in ESD protection exceeds 2000-V HBM and 1000-V CDM, and latch-up performance exceeds 100 mA per JESD 78 Class II.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface with 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains |
| Max tpd | 4.6 ns at 3.3 V - ensures sub-5-ns signal path timing for high-speed bus buffering |
| Output Drive | ±24 mA at 3.3 V - drives standard CMOS loads and short PCB traces without external buffers |
| Ioff Current | ±10 µA max - blocks damaging current flow during hot-swap or partial power-down |
| Input Voltage Tolerance | Up to 5.5 V - allows 5-V inputs to be safely translated down to lower VCC rails |
| VOLP / VOHV | <0.8 V / >2 V at 3.3 V - suppresses ground bounce and supply undershoot in dense layouts |
| Operating Temp | –40°C to +125°C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
SN74LVC2G240YZAR uses an 8-ball DSBGA (YZP) package measuring 1.5 mm × 1.5 mm × 0.5 mm, with bottom-side ball layout optimized for minimal PCB footprint and thermal performance. Pin 1 is located at corner A1 (top-left when orientation mark is upright).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | 1A (Input) | First buffer input; accepts 0–5.5 V regardless of VCC |
| A2 | 1OE (Enable) | Active-low enable for first buffer; tie high via pullup for power-up high-Z safety |
| B1 | 2A (Input) | Second buffer input; electrically identical to 1A |
| B2 | 2OE (Enable) | Active-low enable for second buffer; independent control from 1OE |
| A3 | 1Y (Output) | Noninverting output of first buffer; 3-state capable, ±24 mA drive |
| B3 | 2Y (Output) | Noninverting output of second buffer; fully isolated from 1Y electrically |
| A4 | VCC | Supply rail; must be decoupled locally due to fast switching transients |
| B4 | GND | Ground reference; shared return for both buffers and enable logic |

| Low ground bounce | VOLP < 0.8 V at 3.3 V - maintains signal integrity in multi-buffer parallel configurations |
| Wide temperature range | –40°C to +125°C operation - meets AEC-Q100 Grade 1 requirements for automotive ECUs |
Applications
| Memory Address Buffering | Industrial I/O Expansion |
|---|---|
Use Scenario: Driving address lines from a low-voltage microcontroller (1.8 V) to legacy SRAM chips requiring 3.3-V or 5-V compatible inputs. IC Role / Device Role / Timing Role: Dual noninverting buffer translating and strengthening address signals while maintaining strict timing (tpd ≤ 4.6 ns) and isolation between channels. Use Value: Eliminates need for discrete level shifters and reduces board area by using single 1.5-mm² DSBGA instead of two discrete translators. | Use Scenario: Interfacing programmable logic controller (PLC) CPU modules with field-mounted sensors operating at varying supply voltages (2.5 V, 3.3 V, 5 V). IC Role / Device Role / Timing Role: Bus-oriented receiver providing 3-state isolation and voltage-tolerant input staging before FPGA or MCU GPIOs. Use Value: Enables hot-plug capability via Ioff and withstands sensor cable-induced transients due to robust ESD (2000-V HBM) and latch-up immunity (>100 mA). |
| Automotive Body Control Module | Portable Medical Device Interface |
Use Scenario: Buffering LIN bus or CAN transceiver control signals within space-constrained body control units exposed to under-hood temperatures. IC Role / Device Role / Timing Role: Signal conditioning and isolation element ensuring reliable enable/disable sequencing across –40°C to +125°C ambient. Use Value: NanoFree™ package survives thermal cycling stress better than leaded packages; guaranteed tdis ≤ 5.5 ns prevents glitch during mode transitions. | Use Scenario: Isolating and driving analog front-end multiplexer select lines in battery-powered ultrasound or ECG devices where leakage and power must be minimized. IC Role / Device Role / Timing Role: Low-static-current (10-µA ICC max) 3-state driver enabling precise channel selection without loading adjacent paths. Use Value: Ultra-low Ioff (±10 µA) prevents signal corruption during sleep modes; 1.65-V minimum VCC extends battery life in deep-sleep states. |
Equivalent & Alternatives

FAQ
What is the maximum input voltage tolerance for SN74LVC2G240YZAR?
The SN74LVC2G240YZAR accepts input voltages up to 5.5 V on all A and OE pins, independent of VCC level. This allows direct interfacing with higher-voltage logic (e.g., 5-V microcontrollers or sensors) while operating at as low as 1.65 V, eliminating external level-shifting components. This specification is validated across –40°C to +125°C and is explicitly defined in the Absolute Maximum Ratings table of the SCES208I datasheet.
Does SN74LVC2G240YZAR support hot-swap or live-insertion applications?
Yes, SN74LVC2G240YZAR supports live insertion via its Ioff feature: when VCC = 0 V, the outputs are disabled and leakage is limited to ±10 µA, preventing damaging back-current flow from live backplanes or powered subsystems. This behavior is tested per JESD 78 Class II latch-up standards and confirmed in the Electrical Characteristics table under Ioff test conditions.
What is the pin 1 location and ball map for SN74LVC2G240YZAR?
SN74LVC2G240YZAR uses a 2×4 DSBGA (YZP) package with ball pitch of 0.5 mm. Pin 1 (1A) is located at the A1 corner - top-left position when the orientation mark (dot or chamfer) is oriented upright. The full ball map is A1=1A, A2=1OE, B1=2A, B2=2OE, A3=1Y, B3=2Y, A4=VCC, B4=GND, as shown in the mechanical drawing YZP0008.
How does SN74LVC2G240YZAR handle power-up sequencing to avoid output glitches?
To ensure high-impedance state during power-up, SN74LVC2G240YZAR requires OE pins to be tied to VCC through a pullup resistor. The minimum resistance is determined by the driver's current-sinking capability - typically ≤10 kΩ suffices. This prevents unintended output activation before VCC stabilizes, a requirement explicitly stated in the Functional Description section of the SCES208I datasheet.
Is SN74LVC2G240YZAR suitable for automotive applications?
Yes, SN74LVC2G240YZAR is qualified for automotive use: it operates across –40°C to +125°C, exceeds 100 mA latch-up immunity per JESD 78 Class II, and features 2000-V HBM ESD protection. Its NanoFree™ YZP package enhances thermal cycling reliability, and TI lists it in automotive-grade product folders - making it appropriate for body control modules, infotainment interfaces, and ADAS sensor hubs.
