Product details
Overview
74AHC2G126DP-Q100 from Nexperia is an automotive-qualified dual 3-state buffer/line driver in TSSOP8 (SOT505-2) package, operating from 2.0 V to 5.5 V with CMOS-level inputs, -40 °C to +125 °C temperature range, and overvoltage-tolerant inputs up to 5.5 V - used for bidirectional signal buffering and voltage-level translation in automotive body control modules.
For engineers reviewing the 74AHC2G126DP-Q100 datasheet, 74AHC2G126DP-Q100 pinout, 74AHC2G126DP-Q100 application, or 74AHC2G126DP-Q100 equivalent, key selection criteria include 3-state enable timing (ten ≤ 9.5 ns at VCC = 5 V), symmetrical output impedance, AEC-Q100 Grade 1 qualification, and input overvoltage tolerance enabling mixed-voltage domain interfacing.
Technical Context
This device implements two independent non-inverting buffers, each with active-HIGH 3-state output enable (1OE, 2OE). Each channel supports rail-to-rail input logic thresholds (VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max), enabling robust noise immunity in noisy automotive environments.
Propagation delay is tightly balanced between channels (tpd ≤ 7.0 ns at VCC = 5 V, CL = 15 pF), and disable time (tdis ≤ 11.0 ns) ensures fast bus release - critical for time-sensitive CAN/LIN subsystem interconnects and multiplexed sensor data routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports direct interface with 3.3 V and 5 V microcontrollers without level shifters. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - enables safe interfacing with higher-voltage peripherals in mixed-supply systems. |
| Propagation Delay (tpd) | ≤ 7.0 ns at VCC = 5 V, CL = 15 pF - ensures sub-10 ns signal path timing for high-speed digital control loops. |
| Enable Time (ten) | ≤ 9.5 ns at VCC = 5 V, CL = 50 pF - guarantees rapid bus arbitration and low-latency peripheral enable/disable. |
| Output Drive Strength | ±8 mA at VCC = 4.5 V - sufficient to drive 15 pF loads across PCB traces and multiple gate inputs. |
| Static Supply Current | ≤ 40 μA at VCC = 5.5 V - enables low-quiescent-power operation in always-on vehicle subsystems. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2), 8 leads, 3 mm body width, 0.65 mm pitch, lead length 0.5 mm - optimized for automated SMT assembly and thermal performance in dense automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 (1OE, 2OE) | Output Enable Input | Active-HIGH control: drives corresponding Y output to high-impedance when LOW; enables simultaneous bus isolation of both channels. |
| 2, 5 (1A, 2A) | Data Input | CMOS-compatible input with overvoltage tolerance up to 5.5 V - accepts signals from 1.8 V, 3.3 V, or 5 V sources without damage or level shifting. |
| 3, 6 (2Y, 1Y) | Data Output | Non-inverting buffered output with symmetrical rise/fall times and ±8 mA drive - maintains signal integrity across stubbed bus topologies. |
| 4 | GND | Ground reference (0 V) - must be low-inductance connection to minimize ground bounce in switching noise-sensitive domains. |
| 8 | VCC | Primary supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including lifetime reliability testing per stress test conditions. |
| Overvoltage-tolerant inputs | Withstands 5.5 V input signals even when VCC = 2.0 V - eliminates need for external clamping diodes in mixed-voltage sensor interfaces. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduced signal distortion on shared buses. |
| Low dynamic power dissipation | CPD = 10 pF per buffer - minimizes switching current and heat generation in high-frequency enable/disable cycling. |
| ESD robustness | HBM > 2000 V, CDM > 1000 V - meets stringent automotive ESD immunity requirements for in-vehicle handling and system integration. |
Applications
| Body Control Module (BCM) | Instrument Cluster Interface |
|---|---|
|
Use Scenario: Isolating and buffering LIN bus transceiver I/O lines during sleep/wake transitions. IC Role / Device Role / Timing Role: Dual 3-state buffer providing controlled enable/disable of signal paths to reduce leakage and prevent bus contention during low-power states. Use Value: Enables deterministic wake-up latency (<9.5 ns enable time) and eliminates cross-talk between dormant and active LIN nodes. |
Use Scenario: Level-shifting and driving multiplexed analog sensor signals (e.g., fuel level, coolant temp) to MCU ADC inputs. IC Role / Device Role / Timing Role: Voltage-tolerant buffer translating 5 V sensor outputs to 3.3 V MCU inputs while maintaining signal fidelity. Use Value: Overvoltage-tolerant inputs eliminate external resistive dividers, reducing BOM count and board space in space-constrained clusters. |
| Door Module Communication Hub | Lighting Control Unit (LCU) |
|
Use Scenario: Managing bidirectional data flow between door handle sensors, window switches, and central gateway via shared I²C-like control bus. IC Role / Device Role / Timing Role: Dual-channel buffer enabling time-multiplexed access to shared serial control lines with precise 3-state timing control. Use Value: Symmetrical output impedance ensures matched edge rates across both channels, minimizing skew-induced timing errors in multi-node polling. |
Use Scenario: Driving PWM-controlled LED strings in adaptive front-lighting systems (AFS) with synchronized enable/disable sequencing. IC Role / Device Role / Timing Role: Fast-enable buffer gating PWM signals to individual LED zones based on vehicle speed and steering angle inputs. Use Value: Sub-10 ns enable/disable timing allows precise zone activation windows, supporting dynamic beam shaping without visible flicker. |
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 |
|---|---|---|---|
| 74AHCT2G126DP-Q100 | TTL-level inputs (VIH = 2.0 V min), identical pinout and timing specs. | Better compatibility with legacy 5 V TTL logic families; less suitable for 3.3 V-only systems with weak drive. | Select when interfacing with older automotive modules using 5 V TTL signaling standards. |
| SN74LVC2G126QDCURQ1 | Lower VCC range (1.65–5.5 V), slightly higher ICC (max 10 μA vs 40 μA), same AEC-Q100 Grade 1. | Superior low-voltage operation down to 1.65 V; tighter VIH/VIL specs improve noise margin in 1.8 V domains. | Prefer for next-gen 1.8 V/3.3 V mixed-signal designs requiring extended low-VCC support. |
Compared with 74AHC2G126DP-Q100, the AHCT variant offers legacy TTL compatibility at the cost of reduced noise immunity in 3.3 V systems, while the LVC variant extends low-voltage operability but trades off slightly higher static current in high-temp operation.

FAQ
Is 74AHC2G126DP-Q100 pin-compatible with 74AHCT2G126DP-Q100?
Yes - both share identical TSSOP8 (SOT505-2) pinout, pin functions, and mechanical footprint. The only functional difference is input logic threshold: AHC uses CMOS levels (VIH ≥ 3.85 V at VCC = 5.5 V), while AHCT uses TTL levels (VIH ≥ 2.0 V). No PCB redesign is needed for substitution.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies dynamic performance up to 50 pF load capacitance, with tpd ≤ 9.5 ns and tdis ≤ 11.0 ns at VCC = 5 V. For stable operation beyond 50 pF, series termination or reduced edge rate (via input RC filtering) is recommended to avoid overshoot and ringing.
Does this part support hot-swap or live-insertion?
No - it lacks dedicated hot-swap protection circuitry such as slew-rate limiting or back-drive prevention. While overvoltage-tolerant inputs improve robustness, applying VCC after signal inputs may cause latch-up or excessive current. Power sequencing (VCC before inputs) is mandatory per JESD78 Class II compliance.
Can 74AHC2G126DP-Q100 be used in 1.8 V systems?
No - its minimum specified VCC is 2.0 V, and VIH/VIL thresholds scale with VCC. At 1.8 V, input recognition becomes unreliable (VIH min ≈ 1.35 V, below typical 1.8 V logic HIGH), and output drive degrades significantly. Use SN74LVC2G126QDCURQ1 instead for true 1.8 V operation.
