SN7405NG4

Overview

The SN7405NG4 is a hex inverter integrated circuit from the Texas Instruments 7400 logic series. It features six independent inverters with open-collector outputs, housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a low-level output current of 16 mA. Propagation delay is specified at 55 ns at 5 V, with an operating temperature range of 0°C to +70°C.

Feature Summary

• Hex inverter configuration with six independent channels
• Open-collector output structure for flexible interfacing
• Standard TTL logic compatibility

Applications

• General-purpose digital signal inversion
• Interface between different logic families
• Driving high-voltage or high-current loads via open-collector capability

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the selected package variant matches the required PCB footprint and thermal management specifications for the intended application environment.

Selection Notes

Select this component when a standard hex inverter with open-collector outputs is required for TTL-compatible circuits. Consider the 14-pin SOIC package constraints and the 16 mA sink current capability. Verify that the 55 ns propagation delay meets the timing requirements of the target system design.

Part Context

This part belongs to the Texas Instruments SN7400 family of logic devices. The SN7405 specifically provides hex inverters with open-collector outputs, distinguishing it from push-pull output variants. It is designed for general-purpose digital applications requiring signal inversion and load driving capabilities within standard TTL voltage levels.

Replacement Considerations

SN7405N is a direct substitute offering identical functionality and pinout compatibility.
