Product details
Overview
74HC1G125GW,165 from Nexperia is a single CMOS bus buffer/line driver with 3-state output, designed for signal isolation and bidirectional bus control in compact logic interfaces. It operates from 2.0 V to 6.0 V, delivers propagation delay as low as 8 ns at VCC = 6.0 V (CL = 50 pF), supports −40 °C to +125 °C ambient range, and features input clamp diodes enabling overvoltage-tolerant interfacing-commonly used in I²C level-shifting, microcontroller GPIO expansion, and low-pin-count peripheral enable gating.
For engineers reviewing the 74HC1G125GW,165 datasheet, 74HC1G125GW,165 pinout, 74HC1G125GW,165 application, or 74HC1G125GW,165 equivalent, key selection criteria include its 5-pin TSSOP5 package, TTL-compatible variant (74HCT1G125GW), 3-state enable timing (ten/tdis ≤ 32 ns), symmetrical output drive (±7.8 mA), and JEDEC-compliant ESD robustness (HBM > 2000 V).
Technical Context
This device implements a non-inverting buffer with active-low 3-state output enable (OE), where output Y follows input A when OE = LOW and enters high-impedance state when OE = HIGH. Its CMOS input structure provides rail-to-rail voltage compatibility and high noise immunity, while the symmetrical output stage ensures matched rise/fall times and balanced load driving capability.
It complies with JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V) standards, supports dual temperature grades (−40 °C to +125 °C), and integrates input clamp diodes that allow safe interface to signals exceeding VCC when used with current-limiting resistors-enabling mixed-voltage domain bridging without external protection components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - Enables direct integration into 3.3 V and 5 V systems without level shifters. |
| Propagation Delay | 8 ns (typ) at VCC = 6.0 V, CL = 50 pF - Supports >20 MHz data rates in buffered signal paths. |
| Output Drive | ±7.8 mA at VCC = 4.5 V - Sufficient to drive 10 LVTTL loads or 15 pF PCB traces without degradation. |
| Enable/Disable Time | 7–32 ns (typ/max) - Ensures clean bus arbitration with minimal contention window in shared-data applications. |
| Input Clamp Diodes | Integrated - Permits safe connection of inputs to voltages up to VCC + 0.5 V using series resistors. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Reduces need for external ESD protection in handheld and industrial I/O designs. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor control PCBs. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable input | Active-LOW control: drives Y to high-Z when HIGH; enables pass-through when LOW. |
| 2 (A) | Data input | CMOS-level input accepting 0 V to VCC; includes clamp diodes for overvoltage tolerance. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output current sinking. |
| 4 (Y) | Data output | Non-inverting buffered output with symmetrical sourcing/sinking capability (±7.8 mA). |
| 5 (VCC) | Supply voltage | Primary power rail; decoupling capacitor required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V–6.0 V operation eliminates need for separate voltage regulators in multi-rail systems. |
| 3-state output control | Active-low OE allows deterministic bus release timing and prevents contention in shared-data lines. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent edge rates and reduced signal distortion. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overcurrent events. |
| Low dynamic power | CPD = 30 pF - minimizes switching power (PD = CPD × VCC² × fi) in battery-powered sensor nodes. |
Applications
| Microcontroller GPIO Expansion | I²C Bus Level Shifting |
|---|---|
Use Scenario: Adding isolated digital outputs to an MCU with limited drive strength or pin count, such as enabling multiple peripherals on a single header. IC Role / Device Role / Timing Role: Non-inverting buffer with 3-state control acts as a programmable output gate, isolating MCU pins from downstream capacitive loads. Use Value: Prevents signal integrity degradation from fan-out >5, reduces MCU firmware overhead by eliminating software-controlled tristate management. | Use Scenario: Interfacing 3.3 V microcontrollers to 5 V I²C peripherals (e.g., EEPROMs, sensors) without dedicated level translators. IC Role / Device Role / Timing Role: Bidirectional buffer configured with pull-up resistors on both sides, leveraging 3-state control to manage directionality via SCL/SDA arbitration. Use Value: Achieves DC-coupled level translation with <10 ns added delay, avoiding timing violations in 400 kHz Fast-mode I²C links. |
| Industrial Sensor Interface | PLC Digital Input Conditioning |
Use Scenario: Buffering noisy analog-to-digital converter (ADC) control signals or digital status flags in factory-floor equipment. IC Role / Device Role / Timing Role: Signal conditioner providing noise-immune transmission between isolated sensor subsystems and main controller logic. Use Value: High noise immunity (>50% VCC) and input clamping protect against EFT bursts common in 24 V industrial environments. | Use Scenario: Isolating and conditioning dry-contact or optocoupler outputs in programmable logic controller (PLC) input modules. IC Role / Device Role / Timing Role: Input line driver converting slow-rising mechanical switch signals into fast, clean logic edges for FPGA or ASIC sampling. Use Value: Propagation delay consistency (±5 ns across temperature) ensures deterministic scan-cycle timing in safety-critical PLC firmware. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT1G125GW,165 | TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 4.5–5.5 V); identical pinout and 3-state behavior. | Better suited for legacy 5 V systems interfacing with older microcontrollers lacking CMOS-level outputs. | Select when driving from 5 V TTL sources; avoid in pure 3.3 V CMOS-only designs due to higher input threshold margin loss. |
| SN74LVC1G125DBVR | Lower VCC range (1.65–5.5 V); faster tpd (5.5 ns typ at 3.3 V); different pinout (SOT-23-5 vs TSSOP5). | Preferred for ultra-low-voltage portable devices and high-speed serial control buses requiring sub-10 ns latency. | Choose for 1.8 V/2.5 V systems or when board space permits SOT-23-5; verify layout compatibility due to footprint mismatch. |
Compared with 74HC1G125GW,165, the 74HCT1G125GW offers superior compatibility with legacy 5 V logic but sacrifices some noise margin in 3.3 V domains, while SN74LVC1G125DBVR delivers higher speed and lower voltage support at the cost of package interchangeability and JEDEC HBM rating (1500 V vs 2000 V).

FAQ
What is the maximum clock/data rate supported by 74HC1G125GW,165?
The device supports reliable operation up to approximately 20 MHz in typical buffered signal paths, based on its 8 ns typical propagation delay (VCC = 6.0 V, CL = 50 pF) and 32 ns maximum disable time. For sustained high-frequency use, ensure PCB trace lengths remain under 5 cm and maintain proper VCC decoupling with a 100 nF ceramic capacitor near pin 5.
Can 74HC1G125GW,165 be used for bidirectional data transfer?
No-it is a unidirectional non-inverting buffer with fixed input (A) and output (Y) terminals. Bidirectional operation requires two devices (one per direction) or a dedicated bus transceiver like 74HC245. The 3-state output enables bus sharing but does not reverse signal flow.
Is there a lead-free and RoHS-compliant version of this part?
Yes, 74HC1G125GW,165 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "GW" suffix denotes the lead-free, halogen-free TSSOP5 package, and the device carries the Nexperia "Green" marking (no Br, Cl, or heavy metals above threshold limits).
How does the input clamp diode affect system-level design?
The integrated input clamp diodes allow safe connection of A to voltages up to VCC + 0.5 V when series current-limiting resistors (e.g., 1 kΩ) are used-enabling direct interfacing with 5 V signals on a 3.3 V-powered device. This eliminates external diode protection but requires resistor sizing to limit IVCC current to <20 mA per Absolute Maximum Ratings.
