Product details
Overview
74AHCT1G07GW,125 from Nexperia is a single-channel CMOS buffer with open-drain output, designed for level translation and wired-OR logic interfacing in mixed-voltage systems. It operates from 4.5 V to 5.5 V, supports -40 °C to +125 °C ambient temperature, delivers ≤0.55 V LOW-level output at 8 mA sink current, and features overvoltage-tolerant inputs up to 5.5 V - enabling direct connection to 3.3 V or 5 V logic domains in industrial I/O expansion.
For engineers reviewing the 74AHCT1G07GW,125 datasheet, 74AHCT1G07GW,125 pinout, 74AHCT1G07GW,125 application, or 74AHCT1G07GW,125 equivalent, key selection criteria include open-drain drive capability, input overvoltage tolerance, propagation delay under 5 ns at 5 V/15 pF, thermal performance in TSSOP5, and compatibility with I²C-bus pull-up configurations.
Technical Context
This device implements a non-inverting buffer stage with an open-drain NMOS output transistor, requiring an external pull-up resistor to define HIGH-state voltage. Its input structure is rated to 5.5 V regardless of VCC, allowing safe interfacing between 3.3 V controllers and 5 V peripherals without level-shifter ICs.
Propagation delays are characterized across temperature and load: tPLZ/tPZL range from 1.0 ns (min) to 7.0 ns (max) at VCC = 4.5–5.5 V and CL = 50 pF, with typical values of 2.5–6.0 ns. Static parameters include VIH = 3.85 V (min), VIL = 1.65 V (max), and VOL ≤ 0.55 V at IO = 8 mA and VCC = 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage (VCC) | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL/CMOS systems and robust noise margin. |
| Input voltage tolerance | Up to 5.5 V - enables use as a level translator from 3.3 V or 5 V inputs into 5 V domains without clamping diodes. |
| Output type | Open-drain - supports wired-OR bus architectures, I²C-bus signaling, and flexible pull-up voltage selection. |
| Propagation delay (tPLZ/tPZL) | ≤7.0 ns max at VCC = 4.5–5.5 V, CL = 50 pF - suitable for high-speed digital control lines and status feedback paths. |
| LOW-level output voltage (VOL) | ≤0.55 V at IO = 8 mA, VCC = 4.5 V - guarantees solid logic LOW under full sink load, critical for reliable bus arbitration. |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-ambient embedded systems. |
| ESD protection | HBM >2000 V, CDM >1000 V - provides robust handling during PCB assembly and field service without additional protection circuitry. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, body width 1.25 mm, pin pitch 0.65 mm, height 1.1 mm - optimized for space-constrained industrial control boards and sensor interface modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - left unconnected on PCB; no routing or thermal consideration required. |
| 2 | A | Non-inverting data input - accepts 0–5.5 V logic signals; overvoltage tolerant independent of VCC. |
| 3 | GND | Ground reference - must be connected to system 0 V plane with low-inductance path for stable switching. |
| 4 | Y | Open-drain output - sinks current only; requires external pull-up resistor to define HIGH voltage level. |
| 5 | VCC | Positive supply - powers internal logic; decoupling capacitor (100 nF) recommended within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 4.5 V to 5.5 V operation - eliminates need for dedicated 5 V regulators in mixed-rail systems. |
| Overvoltage-tolerant inputs | 5.5 V absolute max input - allows direct interface to 3.3 V microcontrollers driving 5 V bus lines. |
| Open-drain output architecture | Supports multi-master bus topologies - enables shared interrupt lines and I²C-compatible signaling. |
| High noise immunity | CMOS input threshold with hysteresis - rejects EMI-induced glitches on long traces in factory automation. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
Applications
| Industrial I/O Expansion | I²C Bus Buffering |
|---|---|
|
Use Scenario: Adding isolated digital input channels to a PLC mainboard using optocoupler outputs tied to a shared 5 V bus. IC Role / Device Role / Timing Role: Acts as a level-translating open-drain driver, converting 3.3 V FPGA status flags into 5 V-compatible bus signals. Use Value: Eliminates discrete MOSFET translators; reduces BOM count by one component per channel while maintaining <7 ns timing integrity. |
Use Scenario: Isolating multiple I²C slave devices on a single bus segment to prevent address conflicts and capacitive loading issues. IC Role / Device Role / Timing Role: Functions as a unidirectional bus buffer with open-drain output, preserving I²C protocol timing and voltage levels. Use Value: Enables reliable signal extension beyond 400 pF capacitance limit; maintains tBUF and tHD:STA compliance per I²C specification. |
| Automotive Sensor Interface | Legacy System Integration |
|
Use Scenario: Interfacing a 3.3 V CAN controller's error flag output to a 5 V dashboard display module's interrupt line. IC Role / Device Role / Timing Role: Provides fault-signal translation with overvoltage-safe input and fast 5 ns propagation to meet ASAM diagnostic latency targets. Use Value: Meets -40 °C to +125 °C automotive ambient requirement; avoids level-shifter IC cost and layout complexity. |
Use Scenario: Connecting modern ARM-based HMI controllers to legacy 5 V parallel port peripherals in medical equipment. IC Role / Device Role / Timing Role: Serves as a bidirectional-capable open-drain buffer for handshake lines (e.g., STB, ACK), driven by 3.3 V logic. Use Value: Supports 5 V pull-ups while accepting 3.3 V inputs - enables drop-in replacement of obsolete 74LS07 without redesigning power rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC1G07GW,125 | Same pinout, identical TSSOP5 package, but AHC family - wider 2.0–5.5 V supply range and lower VOL at 3.3 V. | Better suited for 3.3 V systems; less ideal for strict 5 V-only designs due to higher static current at VCC = 5.5 V. | Select when mixed-voltage translation (e.g., 3.3 V → 5 V) is required alongside low-power operation. |
| SN74LVC1G07DBVR | TI LVC variant in SOT-23-5; 1.65–5.5 V supply; VOL = 0.55 V @ 24 mA; slightly faster tPD (3.5 ns typ). | Higher sink current rating enables stronger bus drive; different pinout (A/VCC/Y/GND/n.c.) requires PCB revision. | Choose for higher drive strength and tighter timing budgets where board rework is acceptable. |
Compared with 74AHCT1G07GW,125, the 74AHC1G07GW,125 offers broader supply flexibility but reduced 5 V noise margin, while SN74LVC1G07DBVR delivers superior sink current and speed at the cost of mechanical incompatibility - making 74AHCT1G07GW,125 optimal for drop-in 5 V industrial replacements.

FAQ
What is the maximum sink current supported by the 74AHCT1G07GW,125 output?
The 74AHCT1G07GW,125 supports up to ±25 mA output current per IEC 60134 limiting values, with guaranteed VOL ≤ 0.55 V at 8 mA sink load and VCC = 4.5 V. Continuous operation above 8 mA requires thermal derating per the TSSOP5 package's 3.3 mW/K derating slope above 74 °C.
Can the 74AHCT1G07GW,125 operate with a 3.3 V supply voltage?
No - the 74AHCT1G07GW,125 is part of the AHCT family, specified only for 4.5 V to 5.5 V operation. For 3.3 V compatibility, use the pin-compatible 74AHC1G07GW,125 variant, which shares the same TSSOP5 package and pinout but supports 2.0–5.5 V supply.
Is the 74AHCT1G07GW,125 pinout compatible with other 5-pin logic buffers in TSSOP5?
Yes - the 74AHCT1G07GW,125 uses standard TSSOP5 (SOT353-1) pinout: Pin 1 = n.c., Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. This matches industry-standard placement for single-gate open-drain buffers including SN74LVC1G07 and 74AHC1G07 variants in the same package.
Does the 74AHCT1G07GW,125 require external pull-up resistors on its output?
Yes - the 74AHCT1G07GW,125 has an open-drain output (Pin 4 = Y) and cannot drive HIGH actively. An external pull-up resistor to VCC or another logic rail is mandatory to establish the HIGH logic level; value selection depends on bus capacitance and rise-time requirements.
What is the operating temperature range certified for the 74AHCT1G07GW,125?
The 74AHCT1G07GW,125 is fully specified and tested from -40 °C to +125 °C ambient temperature, meeting industrial and extended-temperature automotive requirements. This range is explicitly confirmed in Table 1 (Ordering Information) and Table 6 (Recommended Operating Conditions) of the official Nexperia datasheet Rev. 11.
