Nexperia USA Inc. 74AHC1G09GW,125

Overview

74AHC1G09GW,125 from Nexperia is a single 2-input AND gate with open-drain output, designed for level translation and wired-AND bus interfacing in mixed-voltage systems. It operates from 2.0 V to 5.5 V, tolerates input voltages up to 5.5 V regardless of supply, and delivers propagation delay as low as 3.2 ns (VCC = 5.0 V, CL = 15 pF). Its -40 °C to +125 °C temperature rating and SOT353-1 (TSSOP5) package support automotive and industrial control applications requiring robust logic-level bridging.

For engineers reviewing the 74AHC1G09GW,125 datasheet, 74AHC1G09GW,125 pinout, 74AHC1G09GW,125 application, or 74AHC1G09GW,125 equivalent, key selection criteria include open-drain drive capability, overvoltage-tolerant inputs, propagation delay vs. load capacitance, and thermal derating behavior above 74 °C in the TSSOP5 package.

Technical Context

The device implements standard AND logic (Y = A · B) with an open-drain output stage, requiring an external pull-up resistor to define HIGH-level voltage and current sourcing. Its input structure enables operation across voltage domains - e.g., 3.3 V logic driving a 5 V bus - without level-shifter ICs.

Static and dynamic performance is specified across full industrial and extended temperature ranges (-40 °C to +125 °C), with VOL ≤ 0.36 V at IO = 8.0 mA (VCC = 4.5 V) and CPD = 5 pF enabling accurate dynamic power estimation. Input clamping current limits (±20 mA) and latch-up immunity (>100 mA per JESD78 Class II Level A) ensure robustness in noisy environments.

FAQ

What is the maximum allowable pull-up resistor value for the open-drain output?

The maximum pull-up resistor depends on required rise time and bus capacitance. With CL = 50 pF and VCC = 5.0 V, a 10 kΩ resistor yields ~350 ns rise time (calculated using τ ≈ R × CL). For I²C fast-mode (400 kHz), 4.7 kΩ is typical. Absolute max sink current is 25 mA, limiting minimum R to ~200 Ω at 5 V.

Can inputs be driven with 5 V while VCC = 3.3 V?

Yes. Inputs are overvoltage tolerant to 5.5 V regardless of VCC. This allows safe interfacing of 5 V sensors or legacy peripherals to a 3.3 V system without external level shifters - a core design advantage confirmed in Section 1 and Table 6 of the datasheet.

Does this device support hot insertion?

No. The datasheet does not specify hot-insertion capability. Input clamping diodes conduct above VCC + 0.5 V, risking excessive current if VCC is unpowered while inputs are active. Always power VCC before applying input signals to avoid violating IIK limits (-20 mA max).

How does thermal derating affect power handling in the TSSOP5 package?

At ambient temperatures above 74 °C, total power dissipation derates linearly at 3.3 mW/K. At 100 °C, Ptot drops to 164 mW (250 mW – 3.3 × 26). This must be accounted for in thermally constrained enclosures - unlike the SC-74A or XSON5 variants, which derate from higher base temperatures.
