NXP Semiconductors 74AHC1G06GW,165

Overview

74AHC1G06GW,165 from NXP Semiconductors is a single high-speed CMOS inverting buffer with open-drain output, designed for level-shifting and wired-logic applications. It operates across 2.0 V to 5.5 V supply voltage, delivers propagation delays as low as 2.7 ns (VCC = 5.0 V, CL = 15 pF), supports −40 °C to +125 °C ambient operation, and requires an external pull-up resistor to establish logic HIGH. It is commonly used in I²C bus interface conditioning and mixed-voltage signal translation.

For engineers reviewing the 74AHC1G06GW,165 datasheet, 74AHC1G06GW,165 pinout, 74AHC1G06GW,165 application, or 74AHC1G06GW,165 equivalent, key selection criteria include open-drain drive capability (8 mA sink at VCC = 4.5 V), CMOS input thresholds, wide temperature range support, and TSSOP5 package compatibility with high-density PCB layouts.

Technical Context

This device implements a single inverting logic function with an open-drain output stage, enabling active-LOW wired-OR and active-HIGH wired-AND configurations when multiple outputs share a common pull-up. Its CMOS input structure provides rail-to-rail voltage recognition and high noise immunity (VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max).

Dynamic performance is characterized by tPZL/tPLZ propagation delays under defined load conditions (CL = 15 pF or 50 pF), with typical values of 2.7 ns / 3.0 ns at VCC = 5.0 V. Static behavior includes sub-100 nA ICC at 25 °C and <0.55 V VOL at IO = 8.0 mA, ensuring reliable LOW-level assertion in bus environments.

FAQ

What is the maximum supply voltage rating for the 74AHC1G06GW,165?

The absolute maximum supply voltage (VCC) for the 74AHC1G06GW,165 is +7.0 V, per IEC 60134 limiting values. However, recommended operation is limited to 2.0 V to 5.5 V. Exceeding 5.5 V during normal use risks permanent damage and violates the device's specified operating conditions. Always observe the 5.5 V upper limit in functional designs.

Does the 74AHC1G06GW,165 require an external pull-up resistor?

Yes, the 74AHC1G06GW,165 has an open-drain output and cannot drive a logic HIGH state internally. An external pull-up resistor to VCC is mandatory to establish a defined HIGH-level output. Typical values range from 1 kΩ to 10 kΩ depending on bus capacitance and rise-time requirements, especially in I²C or interrupt-line applications.

Can the 74AHC1G06GW,165 operate at 3.3 V supply?

Yes, the 74AHC1G06GW,165 is fully specified for 3.3 V operation (VCC = 3.0 V to 3.6 V). At this voltage, it delivers tPZL/tPLZ delays of 3.7 ns / 4.8 ns (CL = 15 pF) and maintains VIH = 2.1 V and VIL = 0.9 V - compatible with standard 3.3 V CMOS logic families. This makes the 74AHC1G06GW,165 ideal for mixed-voltage interface design.

What is the output sink current capability of the 74AHC1G06GW,165?

The 74AHC1G06GW,165 can sink up to 8.0 mA while maintaining VOL ≤ 0.55 V at VCC = 4.5 V and ambient temperature up to +125 °C. At lower currents (e.g., 50 µA), VOL is ≤ 0.1 V. This sink strength supports direct driving of LEDs, optocouplers, and standard I²C bus loads without additional buffering stages.

Is the 74AHC1G06GW,165 suitable for automotive applications?

No - the 74AHC1G06GW,165 is not automotive-qualified. Although it operates from −40 °C to +125 °C, NXP explicitly states that unless otherwise designated, products like the 74AHC1G06GW,165 are non-automotive qualified and lack AEC-Q100 certification, automotive-grade screening, or guaranteed PPAP documentation. Use only in industrial or commercial systems.
