74AHC1G09GV,125

Overview

The Nexperia 74AHC1G09GV,125 is a single 2-input AND gate with an open-drain output, manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device utilizes CMOS technology for low power dissipation and high noise immunity. It is housed in the SC-74A (SOT753) surface-mounted package with five leads. The component supports an operating temperature range from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Open-drain output configuration suitable for mixed-voltage translation applications.
• Overvoltage tolerant inputs allowing operation in environments with voltages up to 5.5 V.
• High noise immunity and CMOS low power dissipation characteristics.

Applications

• Mixed voltage logic translation between different supply domains.
• General purpose digital logic processing requiring AND functionality.
• Low power consumer electronics utilizing CMOS logic families.

Procurement Notes

Verify the specific ordering suffix GV corresponds to the SC-74A package when sourcing. Confirm RoHS compliance status through official Nexperia documentation prior to integration. Ensure design margins account for the specified absolute maximum ratings to prevent permanent damage during operation or storage conditions.

Selection Notes

Select this component when an open-drain AND gate is required for interfacing with higher voltage buses than the logic supply. The SC-74A package offers a compact footprint for space-constrained designs. Consider the propagation delay specifications relative to the target clock frequency and load capacitance to ensure signal integrity in the application circuit.

Part Context

This part belongs to the 74AHC1G series of single-function gates from Nexperia. The AHC logic family provides high-speed performance comparable to standard TTL while maintaining CMOS low power consumption. The 74AHC1G09 specifically implements a two-input AND function with an open-drain output stage, distinguishing it from push-pull variants.

Replacement Considerations

The 74AHC1G09GW is a pin-compatible alternative packaged in TSSOP5. Designers must verify that the thermal and mechanical constraints of the target PCB accommodate the SOT753 package dimensions if substituting with other variants in the same logical family.

FAQ

What is the logic state of the output when both inputs are HIGH?

When both inputs A and B are HIGH, the open-drain output enters a high-impedance OFF-state rather than driving a HIGH voltage level.

Can this device be used for partial power-down applications?

No, the 74AHC1G09 does not include I_OFF circuitry for partial power-down mode operation; it is designed for standard active modes within its specified voltage range.
