SN74S09NG4

Inverter Gates Overview

The SN74S09NG4 is a quad 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the SN54/74S Schottky TTL logic family and features open-collector outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 9 ns, a low-level output current capability of 20 mA, and a high-level output current of 250 uA. It is housed in a 14-pin PDIP package and supports an operating temperature range from 0°C to +70°C.

Inverter Gates Feature Summary

• Integrates four independent 2-input AND gates within a single integrated circuit.
• Features open-collector outputs designed for wired-AND logic configurations.
• Utilizes Schottky transistor technology to achieve high-speed switching performance.

Inverter Gates Applications

• Digital logic circuits requiring multiple AND operations
• Wired-AND bus implementations
• General-purpose digital signal processing

Inverter Gates Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm that the open-collector output configuration matches the system design requirements, particularly regarding external pull-up resistor needs. Ensure the PDIP-14 through-hole package aligns with the target PCB footprint and assembly process specifications.

Inverter Gates Selection Notes

Select this component when high-speed Schottky TTL performance is required alongside the flexibility of open-collector outputs. It serves as a direct functional replacement for standard SN74S09 devices while offering enhanced environmental compliance. Consider the 20 mA sink current capability for driving moderate loads directly without additional buffering stages.

Inverter Gates Part Context

This part is a member of the Texas Instruments SN54/74S series, which represents the Schottky TTL logic family known for improved speed over standard TTL variants. The SN74S09 specifically provides quad 2-input AND functionality. The 'G4' designation typically denotes lead-free packaging and adherence to specific environmental directives defined by the manufacturer.

Inverter Gates Replacement Considerations

The SN74S09N is a compatible alternative within the same product line. Verify pinout compatibility and ensure the non-green variant meets project environmental regulations if applicable.
