Overview
The SN7406DRE4 is a hex inverter buffer and line driver from the Texas Instruments SN7406 series, housed in a 14-pin SOIC package. It features six open-collector outputs with a minimum breakdown voltage of 30 V. The device operates within a supply voltage range of 4.75 V to 5.25 V, drawing a maximum quiescent current of 51 uA. It provides a low-level output current capability of 40 mA and exhibits a propagation delay of 23 ns at 5 V. The component supports surface-mount installation and functions reliably across an operating temperature range of 0°C to +70°C.
Feature Summary
- Hex inverting buffer configuration with high-voltage open-collector outputs capable of driving loads such as lamps or relays.
- Input clamping diodes integrated to simplify system design and protect against transient voltages.
- Full compatibility with standard TTL input logic levels for seamless integration into existing digital circuits.
Applications
- Converting TTL voltage levels to MOS logic levels
- Driving indicator lights and relay coils via open-collector outputs
- Inverting buffers for standard TTL inputs
Procurement Notes
Verify the specific ordering suffix 'E4' corresponds to lead-free and RoHS-compliant manufacturing standards as defined by Texas Instruments. Confirm the package designation matches the required SOIC-14 footprint for PCB layout compatibility. Ensure the voltage rating aligns with the target circuit's power supply constraints before finalizing procurement specifications.
Selection Notes
Select this component when a hex inverter with high-voltage tolerance is required for interfacing between different logic families. The open-collector architecture allows for wired-OR connections and direct driving of non-TTL loads. Consider the 40 mA sink capability and 30 V breakdown voltage when designing circuits involving inductive loads or higher voltage signaling interfaces.
Part Context
This part belongs to the SN7400-series bipolar logic family, specifically designed as a hex inverter with open-collector outputs. It serves as a robust interface solution for applications requiring signal inversion and level shifting between TTL and other logic standards. The device is widely used in general-purpose digital systems where high-voltage output switching is necessary.
Replacement Considerations
The SN7406DR is a compatible alternative within the same product family offering identical electrical characteristics and functionality. Verify that any substitute maintains the same SOIC-14 package dimensions and pinout configuration to ensure mechanical interchangeability without redesigning the printed circuit board.
