74AHC1G09SE-7

Overview

The 74AHC1G09SE-7 is a single 2-input positive AND gate with an open-drain output, manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and features Schmitt trigger inputs for tolerance against slow input transitions. The device provides 8mA sink current at 5.0V and includes ESD protection exceeding 200V machine model, 2000V human body model, and 1000V charged device model standards. It is housed in a SOT353 package.

Feature Summary

• Single 2-input positive AND gate with open-drain output
• Schmitt trigger action at all inputs
• ESD protection per JESD 22 standards
• CMOS low power consumption

Applications

• General purpose logic
• PCs, networking, notebooks, netbooks, PDAs
• Computer peripherals, hard drives, CD/DVD ROM
• TV, DVD, DVR, set top box
• Personal Navigation / GPS

Procurement Notes

Verify the specific ordering suffix 'SE' corresponds to the SOT353 package configuration as documented in the manufacturer's datasheet. Confirm that the required pull-up resistor is included in the design, as the open-drain output cannot achieve a high state without external circuitry. Ensure compliance with RoHS and lead-free manufacturing specifications if applicable to the project requirements.

Selection Notes

Select this component when a compact 2-input AND function with open-drain capability is required. The open-drain output allows for active-low wired-OR or active-high wired-AND configurations. Consider the Schmitt trigger inputs if the application involves signals with slower rise and fall times. Verify that the operating voltage range aligns with the system's power supply constraints.

Part Context

This part belongs to the 74AHC1Gxx series of single-gate logic devices from Diodes Incorporated. These components are designed for general-purpose digital applications requiring low power consumption and high noise immunity. The AHC logic family offers performance comparable to standard CMOS while maintaining compatibility with TTL logic levels across various supply voltages.

Replacement Considerations

Direct substitutes include other 74AHC1G09 variants from different manufacturers offering identical logical functions and pinouts. Ensure any replacement maintains the open-drain output characteristic and supports the required Schmitt trigger input functionality. Verify package compatibility if physical footprint constraints exist.
