Overview
74LV244PW-Q100 from Nexperia is an automotive-grade octal 3-state buffer/line driver in TSSOP20 package, operating from 1.0 V to 5.5 V supply, featuring dual independent output enables (1OE, 2OE), ±35 mA output drive, and AEC-Q100 Grade 1 qualification for under-hood control modules.
For engineers reviewing the 74LV244PW-Q100 datasheet, 74LV244PW-Q100 pinout, 74LV244PW-Q100 application, or 74LV244PW-Q100 equivalent, key selection criteria include 3-state timing (tdis ≤ 26 ns at VCC = 3.6 V), input voltage compatibility with TTL levels (VCC ≥ 2.7 V), and low-voltage operation down to 1.0 V with guaranteed functionality.
Technical Context
This device implements two independent 4-bit non-inverting buffer sections, each controlled by a dedicated active-low output enable (1OE for Y0–Y3, 2OE for Y0–Y3). Inputs include clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
It supports mixed-voltage system interfacing: accepts TTL input thresholds at VCC = 2.7 V to 3.6 V, delivers VOH ≥ 2.82 V (IO = –8 mA) and VOL ≤ 0.40 V (IO = 8 mA) at VCC = 3.0 V, and maintains 3-state leakage < 10 μA over –40 °C to +125 °C.

Pinout & Package
TSSOP20 package (SOT360-1), 4.4 mm body width, 0.65 mm pitch, 20-pin surface-mount outline optimized for high-density automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output enables - Independently disable Group 1 (pins 12,14,16,18) or Group 2 (pins 3,5,7,9) outputs to high-impedance state. |
| 2,4,6,8 | 1A0–1A3 | Group 1 data inputs - Connect to upstream logic (e.g., microcontroller port pins) driving first 4 buffered outputs. |
| 17,15,13,11 | 2A0–2A3 | Group 2 data inputs - Accept second set of signals (e.g., sensor data bus lines) for independent buffering. |
| 12,14,16,18 | 1Y0–1Y3 | Group 1 buffered outputs - Deliver non-inverted, level-shifted, and driven signals to downstream loads (e.g., display drivers). |
| 3,5,7,9 | 2Y0–2Y3 | Group 2 buffered outputs - Provide isolated signal paths for redundant control lines or multi-drop bus segments. |
| 10 | GND | Ground reference - Must be connected to low-impedance chassis or power plane to minimize ground bounce (VOLP < 0.8 V at 3.3 V). |
| 20 | VCC | Supply rail - Decoupling capacitor (100 nF) required within 5 mm to suppress switching noise and ensure stable 3-state transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 3-state control | Separate 1OE and 2OE pins allow selective isolation of two 4-bit data paths-critical for bidirectional bus arbitration in automotive gateways. |
| Wide VCC range (1.0–5.5 V) | Eliminates need for level shifters when interfacing 1.2 V FPGA I/O with 5 V legacy sensors or actuators in mixed-supply ECUs. |

Applications
| Engine Control Unit Bus Buffer | ADAS Camera Interface Isolation |
|---|---|
Use Scenario: Isolating microcontroller GPIOs from noisy injector driver circuits while maintaining real-time diagnostic feedback. IC Role / Device Role / Timing Role: Octal non-inverting buffer with independent 3-state control acts as directionally agnostic signal conditioner between MCU and high-current peripheral drivers. Use Value: Prevents backfeed into MCU I/O during fault conditions; ±35 mA drive ensures clean edges on 50 Ω traces even with 100 pF load capacitance. | Use Scenario: Level-shifting and isolating MIPI CSI-2 parallel clock/data lanes between image sensor and SoC in parking camera modules. IC Role / Device Role / Timing Role: Low-skew buffer preserves setup/hold timing margins across 8-bit parallel video bus while enabling hot-plug detection via 3-state control. Use Value: 9 ns propagation delay (VCC = 3.3 V) and < 26 ns disable time meet 25 MHz pixel clock timing budgets; 1.0 V min VCC supports ultra-low-power standby modes. |
| LIN Transceiver Signal Conditioning | Body Control Module I/O Expansion |
Use Scenario: Driving LIN bus master output and conditioning slave response signals in door module ECUs with shared VCC domains. IC Role / Device Role / Timing Role: Dual-group buffer provides separate enable control for transmit and receive paths, eliminating bus contention during frame arbitration. Use Value: TTL-compatible inputs at VCC = 3.3 V accept direct connection to LIN transceiver logic outputs; integrated clamp diodes tolerate transient coupling from 12 V power rails. | Use Scenario: Expanding GPIO count for LED matrix control and switch monitoring in smart junction boxes with thermal constraints. IC Role / Device Role / Timing Role: 3-state outputs allow dynamic reconfiguration of shared data buses among multiple submodules (e.g., mirror, seat, lighting controls). Use Value: 10 μA max 3-state leakage prevents false triggering of high-impedance sense inputs; TSSOP20 footprint saves >30% board area vs. SO20 alternative. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar octal 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC244APWR | Non-automotive grade; rated –40 °C to +125 °C but not AEC-Q100 qualified; slightly higher ICC (max 160 μA vs. 100 μA at VCC = 5.5 V). | Acceptable for industrial or consumer applications where automotive reliability certification is not mandated. | Select when cost sensitivity outweighs AEC-Q100 requirement and thermal derating margin is sufficient. |
| 74LVT244PW,118 | Higher drive (±64 mA); requires minimum VCC = 2.7 V; no 1.0 V operation; lacks input clamp diodes. | Suitable for high-speed backplane interfaces but incompatible with sub-2.7 V domains or overvoltage-tolerant designs. | Choose only if higher output current is essential and system operates exclusively above 2.7 V with clean supply rails. |
Compared with SN74LVC244APWR and 74LVT244PW,118, the 74LV244PW-Q100 uniquely combines AEC-Q100 Grade 1 qualification, 1.0 V operational capability, and integrated input clamps-making it the sole choice for safety-critical, mixed-voltage, and overvoltage-prone automotive subsystems.

FAQ
What is the minimum supply voltage at which 74LV244PW-Q100 guarantees functional operation?
The device guarantees full functionality-including input recognition, output drive, and 3-state control-at VCC = 1.0 V, with DC characteristics specified from VCC = 1.2 V to 5.5 V. At 1.0 V, logic levels are referenced to GND or VCC, and propagation delay increases to 50 ns (typical), making it suitable for ultra-low-power wake-up and diagnostic states.
Can 74LV244PW-Q100 safely interface with 5 V logic while powered from 3.3 V?
No-inputs must remain within 0 V to VCC. However, the integrated input clamp diodes allow safe connection to voltages up to VCC + 0.5 V when used with external current-limiting resistors (e.g., 10 kΩ to a 12 V wake line), enabling robust interface with higher-voltage automotive subsystems without level shifters.
How does the dual output enable architecture improve system-level reliability?
Independent 1OE and 2OE pins permit selective disabling of either 4-bit group-enabling phased power-down, fault containment (e.g., isolating a failed sensor channel), and dynamic bus arbitration without disrupting other data paths. This reduces single-point failure risk in safety-critical communication gateways and distributed control networks.
Is thermal derating required for continuous operation at +125 °C ambient?
Yes-total power dissipation must be derated linearly at 10.0 mW/K above +100 °C for the TSSOP20 (SOT360-1) package. At +125 °C, maximum allowed Ptot drops to 250 mW (500 mW − 25 K × 10.0 mW/K), requiring careful layout with thermal vias and copper pour to maintain junction temperature below 150 °C under worst-case load.
