Product details

Overview

74AHCT1G07GV,125 from Nexperia is a single non-inverting buffer IC with open-drain output, designed for level-shifting and wired-AND logic implementation in 5 V TTL-compatible digital systems. It operates from 4.5 V to 5.5 V, delivers 8 mA sink current at V_CC = 4.5 V, supports −40 °C to +125 °C ambient range, and features 2.8 ns typical t_PZL propagation delay (CL = 15 pF). It is commonly used in I²C bus pull-up interfaces and mixed-voltage signal conditioning.

For engineers reviewing the 74AHCT1G07GV,125 datasheet, 74AHCT1G07GV,125 pinout, 74AHCT1G07GV,125 application, or 74AHCT1G07GV,125 equivalent, key selection criteria include TTL input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), open-drain drive capability, industrial temperature rating, and SC-74A (SOT753) package compatibility with high-density PCB layouts.

Technical Context

This device implements a single-channel unidirectional buffer with CMOS output stage configured as an open-drain transistor-requiring external pull-up for HIGH-level assertion. Its TTL-compatible inputs accept standard 5 V logic thresholds, enabling direct interfacing with legacy 74LS and microcontroller GPIOs without level translators.

Internal design enforces strict static and dynamic behavior: input leakage remains ≤2.0 µA across full temperature range; OFF-state output leakage is ±10.0 µA at V_CC = 5.5 V; and propagation delays are characterized under defined load (15/50 pF) and supply (4.5–5.5 V) conditions per IEC 60134 test methodology.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Non-inverting buffer with open-drain output - enables wired-AND/wired-OR bus topologies and voltage-level translation.
Supply Voltage Range	4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and CMOS systems; excludes 3.3 V operation.
Input Thresholds	V_IL ≤ 0.8 V, V_IH ≥ 2.0 V - matches TTL logic families, allowing direct connection to 74LS, 74F, and MCU outputs without interface circuitry.
Output Sink Current	8.0 mA at V_CC = 4.5 V, V_OL ≤ 0.55 V - supports driving standard 1 kΩ pull-ups on I²C or SMBus lines at 100 kHz.
Propagation Delay	t_PZL = 2.8 ns (typ), t_PLZ = 3.9 ns (typ) at V_CC = 5.0 V, CL = 15 pF - suitable for high-speed control signaling up to ~100 MHz clock domains.
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range power supply monitoring.

Pinout & Package

74AHCT1G07GV,125 is housed in the SC-74A (SOT753) plastic surface-mounted package: 5-lead, 1.25 mm body width, 0.65 mm lead pitch, and 1.2 mm × 1.5 mm footprint - optimized for space-constrained applications including wearables and sensor nodes.

Pin/Terminal	Circuit Role	Design Meaning
1 (n.c.)	No-connect terminal	Internally unconnected; must remain floating or grounded per layout best practice - no routing or soldering required.
2 (A)	Data input	TTL-compatible input accepting 0 V to 5.5 V; VIH ≥ 2.0 V guarantees HIGH recognition; input capacitance ≤10 pF minimizes loading on driving source.
3 (GND)	Ground reference	0 V return path for all internal logic and output stage; requires low-inductance connection to system ground plane.
4 (Y)	Open-drain output	Drain of N-channel MOSFET - sinks current when active LOW; floats (high-impedance) when inactive; requires external pull-up resistor for logic HIGH.
5 (V_CC)	Supply voltage	Primary 4.5–5.5 V power rail; decoupling capacitor (100 nF ceramic) recommended within 5 mm of this pin for noise immunity.

Key Features

Feature	Design Value
Open-drain output architecture	Enables bidirectional bus sharing (e.g., I²C SDA/SCL), eliminates contention in multi-driver systems, and simplifies level translation between 5 V and lower-voltage domains.
TTL input switching levels	Guarantees interoperability with legacy 74LS, 74F, and microcontroller GPIOs without level-shifting components - reduces BOM count and layout complexity.
−40 °C to +125 °C operation	Validated performance across full industrial and automotive under-hood temperature ranges - supports deployment in motor control, battery management, and harsh-environment sensing.
Low dynamic power dissipation	CPD = 6.5 pF enables sub-1 mW active power at 1 MHz (V_CC = 5 V), critical for always-on status indicators and low-duty-cycle wake-up circuits.
High ESD robustness	HBM > 2000 V rating allows safe handling during manual assembly and withstands transient events in field-deployed equipment without protection diodes.

Applications

I²C Bus Interface	GPIO Expansion Logic
Use Scenario: Driving I²C SDA line shared among multiple masters and slaves with varying supply voltages (e.g., 5 V MCU and 3.3 V sensor). IC Role / Device Role / Timing Role: Acts as a passive bus buffer: isolates voltage domains while preserving signal integrity and timing margins via controlled rise/fall characteristics. Use Value: Eliminates need for discrete MOSFET level shifters; supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C timing with <5 ns propagation skew.	Use Scenario: Expanding microcontroller GPIO count to drive LEDs, relays, or optocouplers requiring higher sink current than native pins provide. IC Role / Device Role / Timing Role: Provides dedicated 8 mA sink capability per channel with TTL-compatible input - simplifies firmware logic by removing software-driven current-limiting calculations.

Equivalent & Alternatives

The following parts are listed as comparable options for similar buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74AHCT1G07GW,125	Same logic function and electrical specs, but packaged in TSSOP5 (SOT353-1) - 2.1 mm × 1.25 mm, 0.65 mm pitch, taller profile (1.1 mm height vs. 1.0 mm).	Preferred for automated optical inspection (AOI) due to exposed lead geometry; less suitable for ultra-thin wearable assemblies.	Select when board real estate allows larger footprint and AOI compatibility is prioritized over minimal Z-height.
SN74LVC1G07DBVR	CMOS-input variant (V_IH = 0.7×V_CC, V_IL = 0.3×V_CC); wider supply range (1.65–5.5 V); lower max sink current (32 mA at V_CC = 3.3 V, but only 8 mA at 5 V).	Better suited for mixed-supply systems (e.g., 1.8 V/3.3 V/5 V domains); not TTL-input compatible - requires level-aware firmware or external resistive dividers for legacy 5 V sources.	Choose for flexible voltage operation and lower static power; avoid if interfacing directly with 74LS or older MCUs lacking CMOS thresholds.

Compared with 74AHCT1G07GV,125, the GW variant offers identical functionality in a slightly larger but more inspectable package, while the SN74LVC1G07DBVR trades TTL compatibility for broader supply flexibility and higher 3.3 V drive - making the GV version optimal for cost-sensitive, purely 5 V industrial control designs requiring guaranteed legacy interoperability.

FAQ

What is the maximum sink current specification for 74AHCT1G07GV,125 at 5.0 V supply?

The 74AHCT1G07GV,125 is rated for 8.0 mA sink current at V_CC = 4.5 V with V_OL ≤ 0.55 V. At exactly 5.0 V, the datasheet confirms identical performance: 8.0 mA sink capability remains valid, and V_OL stays ≤ 0.55 V under that load. This value is measured across the full −40 °C to +125 °C operating range and supports reliable I²C bus termination and LED drive applications.

Does 74AHCT1G07GV,125 support 3.3 V logic inputs?

No, 74AHCT1G07GV,125 does not reliably recognize 3.3 V as a HIGH input level. Its TTL-compatible input threshold requires V_IH ≥ 2.0 V minimum, but the device is only specified for V_CC = 4.5–5.5 V operation. Applying 3.3 V to the input while V_CC = 5 V may result in marginal or undefined switching behavior. For 3.3 V systems, use the 74AHC1G07GV,125 (CMOS-input) or SN74LVC1G07DBVR instead.

Can 74AHCT1G07GV,125 be used without an external pull-up resistor?

No, 74AHCT1G07GV,125 cannot function correctly without an external pull-up resistor on the Y output. Its open-drain output only actively pulls LOW; it presents high impedance when inactive. Without a pull-up, the output remains floating and undefined. Typical values range from 1 kΩ (for 100 kHz I²C) to 10 kΩ (for low-power status indicators), selected based on speed and current budget.

Is 74AHCT1G07GV,125 qualified for automotive applications?

The 74AHCT1G07GV,125 is not officially automotive-qualified per AEC-Q100. While it operates from −40 °C to +125 °C - matching many automotive under-hood temperature requirements - Nexperia explicitly states in its legal disclaimers that non-automotive-qualified products lack automotive-specific testing and warranty. For automotive use, specify AEC-Q100-qualified equivalents such as 74AHCT1G07GV-Q100.

What is the pin 1 marking identifier for 74AHCT1G07GV,125?

The 74AHCT1G07GV,125 uses "C07" as its top-side marking code. Pin 1 is located at the lower-left corner of the SC-74A (SOT753) package, identified by a small dot or notch adjacent to the marking - consistent with JEDEC MO-203AA outline standards. This marking is confirmed in Table 2 of the official Nexperia datasheet Rev. 7.
