Product details
Overview
74LV244D-Q100 from Nexperia is an automotive-grade octal 3-state buffer/line driver in SO20 (SOT163-1) package, featuring dual independent 4-bit channels with separate active-low output enables (1OE, 2OE), 1.0 V to 5.5 V supply operation, and AEC-Q100 Grade 1 qualification for under-hood control modules.
For engineers reviewing the 74LV244D-Q100 datasheet, 74LV244D-Q100 pinout, 74LV244D-Q100 application, or 74LV244D-Q100 equivalent, this device supports low-voltage bus interfacing in automotive body control units, infotainment data routing, and ECU signal conditioning where rail-to-rail input compatibility and high-impedance isolation are required.
Technical Context
This CMOS buffer implements two independent 4-bit non-inverting data paths, each controlled by a dedicated active-low output enable (1OE for Y0–Y3, 2OE for Y0–Y3). Inputs include clamp diodes enabling safe interface to voltages exceeding VCC when used with current-limiting resistors.
It operates across -40 °C to +125 °C with guaranteed functionality down to 1.0 V supply, accepts TTL-level inputs at VCC = 2.7 V–3.6 V, and delivers typical propagation delays of 8 ns (VCC = 3.3 V, CL = 15 pF) and disable times of 13 ns under same conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 5.5 V - Enables direct integration into 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V automotive subsystems without level shifters. |
| Operating Temperature | -40 °C to +125 °C - Qualified for engine compartment and transmission control applications per AEC-Q100 Grade 1. |
| Propagation Delay | 8 ns @ VCC = 3.3 V, CL = 15 pF - Supports >100 MHz data throughput in CAN/LIN gateway buffering and sensor data aggregation. |
| Output Drive Strength | ±8 mA @ VCC = 3.0 V - Sufficient to drive 50 pF loads over 10 cm PCB traces in distributed automotive ECUs. |
| Input Clamp Diodes | Integrated - Allows safe connection of inputs to voltages up to VCC + 0.5 V using external current-limiting resistors. |
| 3-State Leakage Current | ≤10 μA @ VCC = 3.6 V - Ensures minimal bus contention during power sequencing or sleep-mode isolation. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Meets stringent automotive board-level ESD immunity requirements without external protection. |
Pinout & Package
74LV244D-Q100 uses the SO20 plastic small outline package (SOT163-1), 7.5 mm body width, 20-pin gull-wing lead frame, rated for surface-mount reflow assembly and automotive thermal cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | 1OE, 2OE | Active-low output enable controls four outputs each; simultaneous assertion places all eight outputs in high-impedance state. |
| 2, 4, 6, 8 | 1A0–1A3 | First 4-bit input channel driving outputs 1Y0–1Y3; compatible with 1.2 V–5.5 V logic levels. |
| 3, 5, 7, 9 | 2Y0–2Y3 | Second 4-bit output bank, independently enabled by 2OE; electrically isolated from first bank. |
| 10 | GND | Reference ground for all I/O and supply; requires low-inductance connection to minimize ground bounce (VOLP < 0.8 V). |
| 11, 13, 15, 17 | 2A0–2A3 | Second 4-bit input channel driving outputs 2Y0–2Y3; identical electrical specs to 1A0–1A3. |
| 12, 14, 16, 18 | 1Y0–1Y3 | First 4-bit output bank, enabled by 1OE; outputs maintain valid VOH/VOL across full temperature range. |
| 20 | VCC | Single supply rail supporting mixed-voltage system interfacing; decoupling capacitor required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from -40 °C to +125 °C in automotive powertrain and chassis systems. |
| Dual independent 4-bit enables | Allows selective isolation of two data buses (e.g., sensor cluster vs. actuator interface) without shared control logic. |
| TTL-input compatibility | Accepts standard TTL voltage thresholds at VCC = 2.7 V–3.6 V, simplifying legacy microcontroller interface. |
| Low ground bounce (VOLP) | Typical <0.8 V @ VCC = 3.3 V ensures signal integrity on shared ground planes in multi-channel modules. |

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 |
|---|---|---|---|
| SN74LVC244AQDRQ1 | TI part uses LVC core; higher drive (±24 mA) but narrower VCC range (1.65–3.6 V); no 1.0 V operation. | Preferred for 3.3 V-only designs requiring stronger drive; unsuitable for 1.2 V or 1.8 V domains. | Select when higher output current is needed and supply is fixed at 3.3 V; verify thermal derating for 125 °C operation. |
| 74LVC244APW-Q100 | Nexperia TSSOP20 variant (SOT360-1); identical electrical specs but 4.4 mm body width and 0.65 mm pitch. | Better suited for high-density layouts; thermal resistance differs (10.0 mW/K derating above 100 °C vs. 12.3 mW/K for SO20). | Choose for space-constrained boards; confirm solder paste volume and reflow profile compatibility with finer-pitch footprint. |
Compared with SN74LVC244AQDRQ1, the 74LV244D-Q100 offers wider supply flexibility (1.0–5.5 V) critical for multi-rail automotive systems, while the 74LVC244APW-Q100 provides identical functionality in a smaller footprint-both lack the 1.0 V operational capability unique to the LV family.

FAQ
What is the minimum supply voltage at which 74LV244D-Q100 guarantees functional operation?
The device is guaranteed to function down to VCC = 1.0 V, with DC characteristics specified from VCC = 1.2 V to 5.5 V. At 1.0 V, only basic logic functionality is ensured; timing parameters and drive strength are not characterized below 1.2 V per datasheet Section 8.
Can 74LV244D-Q100 safely interface with 5 V logic inputs while operating at 3.3 V supply?
No - inputs must remain within 0 V to VCC. However, integrated input clamp diodes allow safe connection to voltages up to VCC + 0.5 V when used with external current-limiting resistors, enabling limited overvoltage tolerance without damage.
How does the dual output-enable architecture improve system-level design?
Separate 1OE and 2OE pins allow independent control of two 4-bit data groups, enabling partial bus isolation (e.g., disabling sensor inputs while keeping actuator outputs active), reducing software overhead, and supporting phased power-down sequences in multi-domain ECUs.
Is thermal derating required for continuous operation at 125 °C ambient?
Yes - for the SO20 package (SOT163-1), total power dissipation derates linearly at 12.3 mW/K above 109 °C. At 125 °C ambient, maximum allowed Ptot drops to ~290 mW; actual dissipation must be calculated using CPD = 35 pF and load conditions per Section 10.
