Product details
Overview
74HC2G125DP-Q100 from Nexperia is a dual 3-state buffer/line driver IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V and CMOS-level inputs. It features two independent non-inverting buffers, each with active-low output enable (1OE, 2OE), enabling bus isolation in multiplexed data paths. Its low power dissipation, high noise immunity, and input clamp diodes support robust interfacing in engine control units and body electronics.
For engineers reviewing the 74HC2G125DP-Q100 datasheet, 74HC2G125DP-Q100 pinout, 74HC2G125DP-Q100 application, or 74HC2G125DP-Q100 equivalent, key selection criteria include its automotive qualification, 3-state output behavior, TSSOP8 package compatibility, and input voltage level compatibility (CMOS for HC variant) in mixed-voltage system interconnects.
Technical Context
This device implements two independent non-inverting buffer stages, each controlled by a dedicated active-low 3-state enable input (1OE, 2OE). The outputs enter high-impedance state when the corresponding OE is HIGH, allowing bidirectional bus sharing without contention.
Input clamp diodes permit safe interface to voltages exceeding VCC when used with current-limiting resistors. Static and dynamic characteristics are fully specified across -40 °C to +125 °C, with propagation delay as low as 8 ns at VCC = 6.0 V and CL = 50 pF, and disable time ≤26 ns under same conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters |
| Operating Temperature | -40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood automotive applications |
| Propagation Delay (tpd) | 8 ns (max) at VCC = 6.0 V, CL = 50 pF - enables reliable timing in high-speed digital control loops |
| Output Drive Strength | ±7.8 mA at VCC = 6.0 V - sufficient to drive standard 50 pF loads with defined VOH/VOL margins |
| Input Clamping Current | ±20 mA - allows external resistor-limited overvoltage tolerance up to VCC + 0.5 V or below GND |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 96 °C (TSSOP8) - derates linearly above 96 °C, supporting thermal design in compact ECUs |
| ESD Protection | HBM >2000 V, CDM >1000 V - exceeds automotive ESD robustness requirements per JS-001/JS-002 |

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 |
|---|---|---|---|
| 74HCT2G125DP-Q100 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5–5.5 V); otherwise identical pinout, package, and timing | Required when interfacing with legacy 5 V TTL outputs; not suitable for 3.3 V-only systems without pull-ups | Select when driving from 5 V microcontrollers or legacy logic families; verify VIH/VIL match with source driver |
| SN74LVC2G125DPWR | Lower VCC range (1.65–5.5 V); higher speed (tpd ≤ 3.7 ns at 3.3 V); non-automotive grade (no AEC-Q100) | Suitable for consumer-grade infotainment or telematics modules where AEC qualification is not mandated | Choose for cost-sensitive, non-safety-critical designs requiring faster propagation or broader low-voltage operation |
Compared with 74HC2G125DP-Q100, the 74HCT2G125DP-Q100 offers TTL input compatibility at the expense of reduced low-VCC flexibility, while the SN74LVC2G125DPWR delivers superior speed and low-voltage support but lacks automotive qualification-making the HC variant optimal for AEC-compliant 3.3/5 V mixed-signal interfaces.

FAQ
Is the 74HC2G125DP-Q100 pin-compatible with the 74HCT2G125DP-Q100?
Yes, both share identical TSSOP8 (SOT505-2) pinout, package dimensions, and functional pin assignments-including 1OE, 1A, 1Y, VCC, GND, 2Y, 2A, and 2OE in the same order. The only functional difference lies in input voltage thresholds: HC uses CMOS levels (VIH ≥ 70% VCC), while HCT uses TTL levels (VIH = 2.0 V min at 4.5–5.5 V).
What is the maximum allowable input voltage when using external clamping resistors?
Per datasheet limiting values, input voltage may exceed VCC by up to 0.5 V (i.e., VI ≤ VCC + 0.5 V) provided input clamping current remains within ±20 mA. This requires selecting a series resistor that limits current to ≤20 mA under worst-case overvoltage-e.g., a 1 kΩ resistor limits current to 5 mA for a 5 V overvoltage above VCC = 5 V.
Does this device support hot-swap or live-insertion on powered buses?
No-while the 3-state outputs prevent contention, the device lacks Ioff protection or power-off isolation. Applying input signals before VCC is stable risks violating absolute maximum ratings (e.g., VI > VCC + 0.5 V), potentially damaging internal structures. Power sequencing must ensure VCC is established prior to applying input signals.
How does the 74HC2G125DP-Q100 handle simultaneous enable/disable of both buffers?
Each buffer operates independently: 1OE controls 1Y, and 2OE controls 2Y. Simultaneous assertion of both OE pins places both outputs in high-impedance state, effectively disconnecting both channels from the bus. Propagation delays (tpd), enable (ten), and disable (tdis) times are individually characterized and match within ±1 ns across channels at identical VCC and load conditions.
