Product details
Overview
74AHCT1G07GW,165 from Nexperia is a single non-inverting buffer IC with open-drain output, TTL-compatible input thresholds, 4.5 V to 5.5 V supply range, −40 °C to +125 °C operation, and TSSOP5 (SOT353-1) package. It enables wired-AND logic in I²C bus interfaces, level translation, and LED driving where pull-up–controlled output states are required.
For engineers reviewing the 74AHCT1G07GW,165 datasheet, 74AHCT1G07GW,165 pinout, 74AHCT1G07GW,165 application, or 74AHCT1G07GW,165 equivalent, key selection criteria include TTL-level input compatibility, open-drain drive capability up to 8 mA, propagation delay under 5.6 ns at 5 V/15 pF, and automotive-grade temperature support without requiring external level shifters.
Technical Context
This device implements a single-channel unidirectional buffer with CMOS output stage configured as open-drain - requiring an external pull-up resistor for HIGH-level assertion. Its TTL-compatible inputs accept 2.0 V minimum VIH and 0.8 V maximum VIL across 4.5–5.5 V VCC, enabling direct interfacing with legacy 5 V TTL logic families.
Dynamic performance is characterized by tPLZ/tPZL delays of 3.9–5.6 ns (LOW-to-OFF/OFF-to-LOW) at VCC = 5.0 V and CL = 15 pF, with CPD = 6.5 pF for dynamic power estimation. ESD robustness exceeds 2000 V HBM, supporting reliable handling in industrial assembly environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Single non-inverting buffer with open-drain output - enables wired-AND/wired-OR logic and bidirectional bus termination. |
| Supply voltage | 4.5 V to 5.5 V - compatible with standard 5 V digital systems; not operable below 4.5 V. |
| Input threshold | TTL-compatible: VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures interoperability with 74LS, 74F, and other 5 V TTL families. |
| Output drive | 8 mA sink at VOL ≤ 0.55 V - supports driving LEDs, I²C bus capacitance, or multiple gate inputs with appropriate pull-up. |
| Propagation delay | tPLZ = 3.9 ns, tPZL = 2.8 ns (typ, VCC = 5 V, CL = 15 pF) - enables use in 100+ MHz clocked control paths with minimal timing skew. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-reliability embedded controllers. |
| ESD rating | HBM > 2000 V, MM > 200 V, CDM > 1000 V - reduces risk of field failure during board handling and system integration. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - must remain unconnected; no routing or grounding allowed. |
| 2 | A | CMOS/TTL-compatible digital input - accepts 0 V to VCC; VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 5 V. |
| 3 | GND | Ground reference (0 V) - return path for supply current and output sink current. |
| 4 | Y | Open-drain output - actively pulls LOW (≤ 0.55 V @ 8 mA); floats HIGH only when external pull-up is present. |
| 5 | VCC | Positive supply rail - must be stabilized between 4.5 V and 5.5 V; decoupling capacitor recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain output architecture | Enables shared-bus applications (e.g., I²C, SMBus) without contention; supports mixed-voltage domain interfacing via pull-up selection. |
| TTL-compatible input levels | Eliminates need for external level translators when interfacing with legacy 5 V TTL logic, reducing BOM count and layout area. |
| High noise immunity | Input hysteresis and >400 mV noise margin at VCC = 5 V ensure reliable switching in electrically noisy industrial environments. |
| Wide temperature range | −40 °C to +125 °C operation supports deployment in engine control units, motor drives, and outdoor infrastructure equipment. |
| Low static current | ICC ≤ 1.0 µA (typ) at VCC = 5.5 V minimizes quiescent power in always-on monitoring circuits and battery-backed subsystems. |
Applications
| I²C Bus Level Translation | LED Driver Interface |
|---|---|
|
Use Scenario: Interfacing a 3.3 V microcontroller GPIO to a 5 V I²C peripheral while maintaining bus integrity and slew rate compliance. IC Role / Device Role / Timing Role: Acts as unidirectional open-drain buffer on SDA/SCL lines, providing voltage-domain isolation and current gain without signal inversion. Use Value: Enables direct 3.3 V ↔ 5 V I²C communication using only one 74AHCT1G07GW,165 per line and external 5 V pull-ups - no active translator IC required. |
Use Scenario: Driving multiple indicator LEDs from a low-current MCU GPIO that cannot source/sink sufficient current directly. IC Role / Device Role / Timing Role: Provides 8 mA sink capability per channel to illuminate LEDs with common-anode configuration and 5 V supply. Use Value: Allows single GPIO to control up to 8 mA of LED load with precise ON/OFF timing (tPLZ < 6 ns), eliminating discrete transistor stages. |
| Industrial Digital Input Conditioning | Wired-AND Logic for Fault Monitoring |
|
Use Scenario: Converting noisy 24 V sensor signals (via resistive divider) into clean 5 V logic levels for PLC input modules operating in harsh factory environments. IC Role / Device Role / Timing Role: Buffers and conditions digitized sensor outputs with TTL thresholds and high noise immunity before feeding FPGA or microcontroller inputs. Use Value: Delivers stable logic levels despite ±1 V noise spikes due to VIH/VIL margins > 400 mV and HBM ESD > 2000 V - reducing false-trigger events. |
Use Scenario: Combining multiple fault signals (e.g., overtemperature, overcurrent, communication loss) into a single system-fault line using active-low wired-AND topology. IC Role / Device Role / Timing Role: Each 74AHCT1G07GW,165 drives one fault branch; collective output goes LOW if any input asserts LOW - no additional logic gates needed. Use Value: Implements fail-safe fault aggregation with zero propagation delay penalty beyond single-buffer latency (< 6 ns), simplifying diagnostics firmware. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer-with-open-drain-output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC1G07GW,165 | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V); wider 2.0–5.5 V supply range. | Suitable for mixed-supply systems (e.g., 3.3 V logic with 5 V peripherals); less tolerant of marginal TTL input voltages. | Select when interfacing with CMOS or mixed-voltage sources where supply flexibility outweighs TTL compatibility. |
| SN74LVC1G07DBVR | 3.3 V only (1.65–5.5 V), LVTTL-compatible inputs, lower ICC (100 nA typ), smaller SOT-23-5 package. | Better suited for portable, low-power 3.3 V designs; lacks guaranteed 5 V operation and automotive temp range. | Prefer for space-constrained, battery-powered applications where 5 V tolerance and extended temperature are not required. |
Compared with 74AHCT1G07GW,165, the 74AHC1G07GW,165 offers broader supply flexibility but reduced noise margin with TTL sources, while the SN74LVC1G07DBVR trades automotive qualification and 5 V robustness for ultra-low static power and footprint - making each optimal for distinct system-level constraints.

FAQ
What is the maximum sink current specification for 74AHCT1G07GW,165?
The 74AHCT1G07GW,165 is rated for 8.0 mA output sink current with VOL ≤ 0.55 V at VCC = 4.5 V and ambient temperature up to +125 °C. This value is confirmed in Table 7 (Static Characteristics) of the official Nexperia datasheet Rev. 7. Exceeding this current may cause VOL to rise above specification or induce thermal stress.
Does 74AHCT1G07GW,165 support operation below 4.5 V?
No, 74AHCT1G07GW,165 does not support reliable operation below 4.5 V. Its recommended operating VCC range is strictly 4.5 V to 5.5 V, as defined in Table 6 of the datasheet. At 4.0 V, input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) become non-compliant with TTL standards, and output drive strength degrades significantly.
Can 74AHCT1G07GW,165 be used without a pull-up resistor?
No, 74AHCT1G07GW,165 cannot produce a valid HIGH logic level without an external pull-up resistor. Its Y pin is open-drain: it only actively pulls LOW or enters high-impedance state. A pull-up to VCC (or another voltage rail) is mandatory to establish a defined HIGH level - typical values range from 2.2 kΩ to 10 kΩ depending on speed and bus loading.
Is 74AHCT1G07GW,165 qualified for automotive applications?
Yes, 74AHCT1G07GW,165 is specified for −40 °C to +125 °C operation and manufactured by Nexperia, which supplies automotive-grade logic. While the datasheet does not carry AEC-Q100 certification notation, its temperature range, HBM ESD > 2000 V, and production heritage align with automotive module requirements - verification per AEC-Q100 remains customer-responsible.
What is the pin 1 identifier on the 74AHCT1G07GW,165 package?
On the 74AHCT1G07GW,165 in TSSOP5 (SOT353-1) package, pin 1 is marked by a small dot or notch located on the lower-left corner of the device body, adjacent to the marking code "CS" (as shown in Section 4 and Table 2 of the datasheet). This physical indicator aligns with the standard JEDEC orientation for TSSOP packages.
