Product details

Overview

74AHCT1G06GW,165 from NXP Semiconductors is a single-channel TTL-input inverting buffer with open-drain output, operating at 4.5 V to 5.5 V supply voltage, delivering 8.0 mA sink current at V_CC = 4.5 V, and specified for −40 °C to +125 °C ambient temperature. It enables wired-AND logic in I²C bus interfaces and level-shifting applications requiring active-HIGH wired-AND or active-LOW wired-OR configurations.

For engineers reviewing the 74AHCT1G06GW,165 datasheet, 74AHCT1G06GW,165 pinout, 74AHCT1G06GW,165 application, or 74AHCT1G06GW,165 equivalent, key selection criteria include its TTL-compatible input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), 5-pin TSSOP5 (SOT353-1) package, open-drain output architecture, and guaranteed operation across extended industrial temperature range.

Technical Context

This device implements a single inverting logic gate with open-drain output, requiring an external pull-up resistor to establish HIGH-level logic states. Its TTL input switching levels ensure compatibility with legacy 5 V logic families while maintaining CMOS power efficiency.

Propagation delays are characterized at V_CC = 4.5–5.5 V with 15 pF and 50 pF loads: t_PZL ≤ 6.3 ns and t_PLZ ≤ 5.6 ns (max, −40 °C to +125 °C, CL = 15 pF). The n.c. (pin 1) terminal is unconnected and must remain floating per design.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - Ensures interoperability with standard 5 V TTL systems without level translation.
Input Thresholds	V_IL ≤ 0.8 V, V_IH ≥ 2.0 V - Matches TTL logic family requirements for reliable signal recognition.
Output Sink Current	8.0 mA at V_CC = 4.5 V - Supports direct driving of typical pull-up resistors in I²C and SMBus buses.
Propagation Delay	t_PZL/t_PLZ ≤ 6.3/5.6 ns (CL = 15 pF, −40 °C to +125 °C) - Enables high-speed digital control in real-time embedded timing paths.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor control environments.
ESD Protection	HBM > 2000 V, MM > 200 V, CDM > 1000 V - Reduces risk of field failure during handling and PCB assembly.
Input Capacitance	C_I ≤ 10 pF - Minimizes capacitive loading on upstream drivers in high-frequency signal chains.

Pinout & Package

74AHCT1G06GW,165 is housed in a 5-lead plastic thin shrink small outline package (TSSOP5, SOT353-1), body width 1.25 mm, with gull-wing leads and pin 1 indicator located on the lower left corner below the marking code "CR".

Pin/Terminal	Circuit Role	Design Meaning
n.c.	Not connected	Must be left unconnected; no internal bond wire or circuit connection.
A	Data input	Inverting logic input; accepts TTL-level signals (0–5.5 V); VIH ≥ 2.0 V, VIL ≤ 0.8 V.
GND	Ground reference	0 V return path for supply and signal currents; requires low-impedance PCB connection.
Y	Data output	Open-drain output; sinks current only; requires external pull-up to define HIGH state.
V_CC	Supply voltage	Positive supply rail (4.5–5.5 V); decoupling capacitor (100 nF) recommended near pin.

Key Features

Feature	Design Value
TTL-compatible inputs	Enables seamless integration into legacy 5 V microcontroller GPIO, UART, and interrupt lines without level shifters.
Open-drain output	Supports wired-AND bus topologies (e.g., I²C, SMBus, interrupt sharing) and bidirectional signal arbitration.
Extended temperature range	Validated operation from −40 °C to +125 °C ensures reliability in engine control units and industrial PLCs.
Low static current	I_CC ≤ 20 µA at V_CC = 5.5 V reduces quiescent power in always-on monitoring circuits.
High noise immunity	Guaranteed 0.7 V noise margin at V_CC = 5 V supports robust operation in electrically noisy motor drive environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar inverting open-drain buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVC1G06GW,165	CMOS input thresholds (V_IL ≤ 0.18×V_CC, V_IH ≥ 0.7×V_CC); wider supply range (1.65–5.5 V).	Better suited for mixed-voltage systems (1.8 V/3.3 V/5 V), but not TTL-compatible.	Select when interfacing with modern low-voltage MCUs; avoid if legacy 5 V TTL sources are present.
SN74LVC1G06DBVR	Same logic function and open-drain output; SOT-23-5 package (larger footprint, different thermal profile).	Higher thermal resistance (R_θJA ≈ 277 °C/W vs. 210 °C/W for SOT353-1) limits high-power-density layouts.	Choose for legacy SOT-23 board compatibility; prefer 74AHCT1G06GW,165 for space-constrained TSSOP5 designs.

Compared with 74LVC1G06GW,165 and SN74LVC1G06DBVR, the 74AHCT1G06GW,165 uniquely delivers TTL input compatibility at 5 V while fitting the compact SOT353-1 footprint-making it optimal for retrofitting legacy 5 V systems without redesigning layout or recalculating pull-up values.

FAQ

What is the maximum sink current specification for 74AHCT1G06GW,165 at 5.0 V supply?

The 74AHCT1G06GW,165 guarantees a minimum output sink current of 8.0 mA at V_CC = 4.5 V and V_OL ≤ 0.55 V over the full −40 °C to +125 °C temperature range. At exactly 5.0 V, the same 8.0 mA rating applies with V_OL ≤ 0.44 V (typical) and ≤ 0.55 V (max), ensuring reliable drive capability for standard 5 V pull-up configurations.

Can 74AHCT1G06GW,165 operate with a 3.3 V supply voltage?

No, the 74AHCT1G06GW,165 is not rated for 3.3 V operation. Its recommended supply voltage range is strictly 4.5 V to 5.5 V, as defined by TTL input threshold requirements (V_IH ≥ 2.0 V, V_IL ≤ 0.8 V). Using 3.3 V may result in undefined logic states and violates the manufacturer's operating conditions.

Is pin 1 of 74AHCT1G06GW,165 internally connected or should it be left floating?

Pin 1 of the 74AHCT1G06GW,165 is marked "n.c." (not connected) in the official datasheet and has no internal bond wire or circuit connection. It must be left floating-neither tied to V_CC, GND, nor any other node-to prevent unintended coupling or leakage paths.

What is the purpose of the open-drain output in 74AHCT1G06GW,165?

The open-drain output of the 74AHCT1G06GW,165 allows multiple outputs to be wired together on a common bus line, enabling active-LOW wired-OR or active-HIGH wired-AND logic functions. This architecture is essential for I²C communication, interrupt sharing, and bus arbitration-requiring only one external pull-up resistor per bus line.

Does 74AHCT1G06GW,165 require a pull-up resistor on its output pin Y?

Yes, the 74AHCT1G06GW,165 absolutely requires an external pull-up resistor on pin Y to establish a valid HIGH logic level. Because the output is open-drain, it can only sink current (pull LOW); without a pull-up, the output remains in high-impedance (floating) state when not actively driven LOW.
