Product details
Overview
74AHCT2G241DC-Q10H from Nexperia is an automotive-qualified dual 1-bit non-inverting buffer/line driver with independent 3-state outputs, TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 2.0–5.5 V supply range, and operation up to +125 °C - used in CAN/LIN bus interface signal conditioning and automotive body control module data routing.
For engineers reviewing the 74AHCT2G241DC-Q10H datasheet, 74AHCT2G241DC-Q10H pinout, 74AHCT2G241DC-Q10H application, or 74AHCT2G241DC-Q10H equivalent, key selection criteria include TTL-level input compatibility, dual independent 3-state control (1OE active LOW, 2OE active HIGH), VSSOP8 package footprint, AEC-Q100 Grade 1 qualification, and propagation delay ≤7.5 ns at 5 V/50 pF.
Technical Context
This device implements two independent non-inverting buffers, each with dedicated output enable: 1OE (active LOW) controls 1Y, and 2OE (active HIGH) controls 2Y. Input overvoltage tolerance to 5.5 V enables mixed-voltage translation between 3.3 V logic domains and 5 V systems without level shifters.
Its TTL-input threshold (VIH = 2.0 V, VIL = 0.8 V) ensures direct compatibility with legacy 5 V microcontrollers and transceivers, while CMOS output structure delivers symmetrical drive strength (±8 mA at VCC = 4.5 V) and balanced rise/fall times under 50 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - supports stable operation across automotive battery voltage transients (e.g., cold-crank down to 4.5 V). |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of TTL logic levels from legacy MCUs or transceivers. |
| Propagation Delay | tpd ≤ 7.5 ns @ VCC = 5.0 V, CL = 50 pF - enables use in high-speed digital control paths up to ~100 MHz toggle rate. |
| Output Drive | ±8 mA @ VCC = 4.5 V - sufficient to drive 50 pF bus loads or multiple CMOS inputs without external buffering. |
| Operating Temp | −40 °C to +125 °C - qualified for engine bay and powertrain control unit environments per AEC-Q100 Grade 1. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive assembly and handling robustness requirements. |
| Power Dissipation | Ptot = 250 mW (derated above 99 °C) - compatible with thermally constrained VSSOP8 PCB layouts in dense ECUs. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; lead pitch 0.65 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-LOW output enable for buffer 1 - drives 1Y to high-impedance when HIGH. |
| 2 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor. |
| 3 | 1A | Inverting input of buffer 1 - accepts TTL/CMOS logic; overvoltage tolerant to 5.5 V. |
| 4 | 2OE | Active-HIGH output enable for buffer 2 - drives 2Y to high-impedance when LOW. |
| 5 | 2Y | Output of buffer 2 - 3-state CMOS output with symmetrical impedance and ±8 mA drive. |
| 6 | 1Y | Output of buffer 1 - independently controllable; shares no internal coupling with 2Y path. |
| 7 | GND | Ground reference - requires low-inductance connection to system ground plane. |
| 8 | 2A | Inverting input of buffer 2 - electrically isolated from 1A; supports independent signal routing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with full reliability testing - suitable for powertrain and chassis modules. |
| Dual independent 3-state control | Separate 1OE (active LOW) and 2OE (active HIGH) pins enable flexible bus arbitration and direction control in half-duplex interfaces. |
| TTL-compatible input thresholds | VIH = 2.0 V min / VIL = 0.8 V max at 5 V supply - eliminates need for external level translators when interfacing with legacy 5 V peripherals. |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC - allows safe connection to 5 V buses while powered from 3.3 V rails in mixed-voltage domains. |
| Low dynamic power consumption | CPD = 10 pF per buffer - limits switching current in high-frequency applications, reducing EMI and thermal load. |
Applications
| Body Control Module (BCM) | Instrument Cluster Interface |
|---|---|
Use Scenario: Routing sensor status signals (door open/closed, seatbelt buckle) from distributed LIN nodes to central BCM MCU. IC Role / Device Role / Timing Role: Dual buffer isolates LIN transceiver I/O from MCU GPIOs while enabling bidirectional signal flow via 3-state control. Use Value: Prevents signal contention during bus arbitration; TTL input compatibility ensures direct connection to legacy LIN transceivers without level-shifting components. |
Use Scenario: Driving segmented LED backlight drivers and SPI-based display controllers in automotive instrument clusters. IC Role / Device Role / Timing Role: Line driver amplifies MCU GPIO outputs to drive higher-capacitance display interface traces and LED sink drivers. Use Value: Symmetrical ±8 mA output drive maintains signal integrity across 15 cm PCB traces; 7.5 ns propagation delay supports 20 MHz SPI clock rates. |
| Engine Control Unit (ECU) Diagnostics | ADAS Camera Power Sequencing |
Use Scenario: Enabling/disabling diagnostic communication lines (K-line or UART) during ECU boot-up and firmware update sequences. IC Role / Device Role / Timing Role: 3-state buffer acts as programmable signal gate, controlled by MCU reset state or firmware flags. Use Value: Independent 1OE/2OE control allows simultaneous gating of K-line TX/RX paths; AEC-Q100 qualification ensures reliability during extended engine runtime. |
Use Scenario: Controlling power-enable sequencing for multi-sensor ADAS camera modules requiring staggered rail activation. IC Role / Device Role / Timing Role: Buffer translates MCU GPIO logic to clean, slew-controlled enable signals for PMICs and LDOs. Use Value: Overvoltage-tolerant inputs accept 5 V supervisor signals while operating from 3.3 V domain; <10 ns timing margins prevent race conditions in critical power-up sequences. |
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 |
|---|---|---|---|
| 74AHCT2G241DP-Q100 | TSSOP8 (SOT505-2) package; 3 mm body width; 0.5 mm lead length vs. VSSOP8's 2.3 mm width and 0.65 mm pitch. | Less board space efficiency; higher thermal resistance (4.6 mW/K derating above 96 °C vs. 4.9 mW/K for VSSOP8). | Select DP variant only if TSSOP8 footprint is already standardized in legacy designs or thermal margin exceeds 250 mW. |
| SN74LVC2G241QDCURQ1 | CMOS input thresholds (VIH = 0.7×VCC), not TTL; max VCC = 5.5 V but VIH = 3.85 V min at 5.5 V - incompatible with 2.0 V TTL logic. | Cannot replace 74AHCT2G241DC-Q10H in systems with true TTL sources; requires redesign of upstream logic interface. | Choose only when migrating to pure CMOS domains and verifying all driving devices meet LVC input thresholds. |
Compared with 74AHCT2G241DP-Q100, the DC variant saves 28 % PCB area and improves thermal performance; versus SN74LVC2G241QDCURQ1, it retains essential TTL compatibility for backward integration with legacy automotive electronics.

FAQ
Is 74AHCT2G241DC-Q10H pin-compatible with 74AHC2G241DC-Q100?
Yes - both share identical VSSOP8 (SOT765-1) pinout and function table, but differ in input threshold behavior: 74AHCT2G241DC-Q10H uses TTL-compatible inputs (VIH = 2.0 V), while 74AHC2G241DC-Q100 requires CMOS-level inputs (VIH = 3.85 V at 5.5 V). Swapping requires verification of upstream driver compatibility.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF load capacitance with guaranteed tpd ≤ 7.5 ns and VOL ≤ 0.55 V at 8 mA sink current. Driving >50 pF may increase propagation delay and degrade edge rates; for >100 pF loads, add series termination or consider a higher-drive buffer.
Can 1OE and 2OE be tied together for single-enable operation?
No - 1OE is active LOW and 2OE is active HIGH, so tying them directly causes conflicting control logic. To implement unified enable, invert one signal externally using a spare gate or use discrete logic to generate complementary enables synchronized to system control timing.
Does this part support hot-swap or live-insertion?
No - the device lacks Ioff protection or power-off isolation. Applying input signals while VCC = 0 V may cause latch-up or excessive ICC due to internal parasitic paths. Always ensure VCC is stable before asserting inputs or outputs in hot-swap systems.
