Product details
Overview
74HCT2G125DP-Q100 from Nexperia is an automotive-qualified dual 3-state buffer/line driver with TTL-compatible inputs, operating from 4.5 V to 5.5 V supply, delivering propagation delay of 15 ns (typ) at VCC = 4.5 V and CL = 50 pF, and supporting ambient temperatures up to +125 °C for engine control and body electronics applications.
For engineers reviewing the 74HCT2G125DP-Q100 datasheet, 74HCT2G125DP-Q100 pinout, 74HCT2G125DP-Q100 application, or 74HCT2G125DP-Q100 equivalent, key selection criteria include TTL-level input compatibility, 3-state output control timing (enable/disable times ≤ 42 ns), AEC-Q100 Grade 1 qualification, and TSSOP8 package thermal performance in constrained automotive PCB layouts.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state output enable (1OE, 2OE). Output states are fully controlled by OE inputs: when low, outputs drive HIGH/LOW per input logic; when high, outputs enter high-impedance state. Input clamp diodes allow safe interfacing to voltages exceeding VCC using external current-limiting resistors.
Designed for automotive signal routing, it supports bidirectional bus isolation and level translation between subsystems. Static input thresholds are fixed at VIH = 2.0 V (min), VIL = 0.8 V (max) across -40 °C to +125 °C, ensuring robust noise immunity in electrically noisy vehicle environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - matches standard automotive 5 V rail with ±10 % tolerance margin |
| Propagation Delay | 15 ns (typ) at VCC = 4.5 V, CL = 50 pF - enables reliable timing in sub-66 MHz digital control loops |
| Enable Time | 15 ns (typ) - ensures fast bus arbitration response in multiplexed sensor networks |
| Disable Time | 15 ns (typ) - minimizes bus contention during hot-swap or mode-switch transitions |
| Input Thresholds | VIH = 2.0 V (min), VIL = 0.8 V (max) - guarantees TTL logic compatibility across full temperature range |
| Output Drive | ±6.0 mA at VCC = 4.5 V - sufficient to drive 50 pF loads over 10 cm PCB traces without added buffering |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds AEC-Q100 requirements for assembly and field reliability |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 (1OE, 2OE) | Active-low output enable | Drives respective buffer output into high-Z when HIGH; synchronizes bus release timing |
| 2, 5 (1A, 2A) | Data input | Accepts TTL-level signals; internal clamp diodes permit overvoltage-safe interface design |
| 3, 6 (2Y, 1Y) | Data output | Non-inverting buffered output with 3-state control; pin order swapped vs. standard logic symbol layout |
| 4 | GND | Reference ground for all I/O and supply; requires low-inductance connection to minimize switching noise |
| 8 | VCC | Primary power supply input; decoupling capacitor (100 nF) required within 5 mm for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for -40 °C to +125 °C operation in engine bay and transmission control units |
| TTL-compatible input levels | Ensures direct interoperability with legacy microcontrollers and sensors without level-shifting circuitry |
| Input clamp diodes | Enables use of series resistors to safely interface to 12 V or CAN transceiver bias rails |
| Low dynamic power dissipation | CPD = 11 pF (enabled), enabling <1 mW average power at 1 MHz toggle rate with 50 pF load |
| High noise immunity | Guaranteed 400 mV noise margin at VCC = 4.5 V, critical for under-hood EMI resilience |
Applications
| Engine Control Unit (ECU) Signal Isolation | Body Control Module (BCM) Bus Multiplexing |
|---|---|
Use Scenario: Isolating diagnostic communication lines between MCU and OBD-II interface while sharing common data bus. IC Role / Device Role / Timing Role: Dual 3-state buffer provides directional signal gating; OE pins synchronized to UART TX/RX handshaking. Use Value: Prevents bus contention during firmware updates; enables hot-plug diagnostics without system reset. | Use Scenario: Sharing a single LIN bus line among multiple door module sensors (window, lock, mirror). IC Role / Device Role / Timing Role: Acts as bidirectional bus switch; one buffer routes MCU-to-sensor commands, the other returns sensor responses. Use Value: Reduces wiring harness count by 33 %; eliminates need for discrete MOSFET switches and associated gate drivers. |
| Advanced Driver Assistance Systems (ADAS) Camera Interface | Electric Power Steering (EPS) Motor Control Feedback |
Use Scenario: Level-shifting and isolating MIPI CSI-2 clock/data lanes between image sensor and SoC in camera ECU. IC Role / Device Role / Timing Role: Buffers parallel clock and sync signals; 3-state control disables outputs during sensor reconfiguration. Use Value: Maintains signal integrity at 100 MHz edge rates; prevents back-driving during sensor sleep/wake transitions. | Use Scenario: Routing position encoder quadrature signals (A/B) from resolver-to-digital converter to EPS MCU. IC Role / Device Role / Timing Role: Provides noise-immune signal conditioning; OE pins tied LOW for continuous monitoring during torque assist cycles. Use Value: Achieves <10 ns timing skew between A/B channels, preserving 0.1° motor angle resolution. |
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 |
|---|---|---|---|
| SN74LVC2G125DBVR | Lower VCC range (1.65–5.5 V); CMOS inputs; 3.3 V optimized; no AEC-Q100 qualification | Suitable only for non-automotive 3.3 V systems; lacks high-temp validation and automotive stress testing | Select only for industrial or consumer designs where AEC-Q100 is not mandated and supply is 3.3 V nominal. |
| 74HC2G125DP-Q100 | CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V); identical pinout, package, and AEC-Q100 Grade 1 rating | Requires compatible CMOS-level drivers; unsuitable for direct replacement with TTL-output MCUs | Choose when interfacing with 5 V CMOS logic or when higher noise margin is prioritized over TTL compatibility. |
Compared with SN74LVC2G125DBVR, the 74HCT2G125DP-Q100 delivers guaranteed TTL input compatibility and automotive qualification but operates strictly at 4.5–5.5 V; versus 74HC2G125DP-Q100, it trades CMOS noise immunity for seamless integration with legacy 5 V TTL peripherals in safety-critical modules.

FAQ
What is the maximum operating temperature for 74HCT2G125DP-Q100?
The device is qualified for continuous operation from -40 °C to +125 °C ambient temperature per AEC-Q100 Grade 1 requirements. Its TSSOP8 package exhibits thermal resistance θJA of 140 K/W, allowing sustained 125 °C case temperature when mounted on 2-layer PCBs with 1 cm² copper pour under the exposed pad (if present) and proper airflow.
Can 74HCT2G125DP-Q100 interface directly with 3.3 V logic outputs?
No - its TTL input thresholds require minimum 2.0 V for HIGH recognition, but 3.3 V logic outputs typically meet this. However, VIH min is specified at VCC = 4.5 V; at VCC = 5.0 V, VIH min rises to 2.0 V, making most 3.3 V CMOS outputs (VOH ≥ 3.0 V) compatible. Always verify actual VOH under load per source device datasheet.
Is the TSSOP8 package lead-free and RoHS compliant?
Yes - the SOT505-2 package uses 100 % matte tin lead finish, complies with EU RoHS Directive 2011/65/EU and China RoHS, and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/85 % RH.
How does the input clamp diode affect external circuit design?
The integrated clamp diodes allow safe connection of inputs to voltages up to VCC + 0.5 V or down to -0.5 V, provided input current remains within ±20 mA. Designers must add series current-limiting resistors (e.g., 1 kΩ) when interfacing to 12 V domains to limit IIK to <12 mA, preventing latch-up and ensuring long-term reliability.
