SN7416N

Overview

The SN7416N is a hex inverter buffer and driver featuring high-voltage outputs, manufactured by Texas Instruments. It belongs to the standard TTL logic family and operates within a supply voltage range of 4.75 V to 5.25 V, with a nominal voltage of 5 V. The device contains six independent inverters and supports a maximum operating frequency of 35 MHz at nominal voltage. Propagation delay is specified at a maximum of 23 ns. It provides a low-level output current (IOL) of up to 40 mA and has a maximum quiescent current of 51 mA. The component is available in 14-pin packages including PDIP, SOIC, and SO.

Feature Summary

• Provides six independent inverting buffers with high-voltage output capabilities suitable for interfacing with higher voltage loads.

Applications

• Driving high-voltage loads such as relays or lamps from standard TTL logic levels.

Procurement Notes

Verify that the specific order corresponds to the SN7416N part number rather than other variants like SN74LS16 or SN74HC16. Confirm the package type matches the required PCB footprint, typically PDIP-14 for through-hole applications. Ensure the supplier source is authorized to guarantee compliance with original manufacturer specifications and quality standards.

Selection Notes

Select this component when high-voltage inversion is required directly from a standard TTL source without external level-shifting circuitry. Consider the 40 mA sink capability for moderate load driving. Evaluate thermal dissipation requirements if multiple channels are actively driven simultaneously under heavy load conditions.

Part Context

This component is part of the Texas Instruments SN74xx series of digital logic integrated circuits. It serves as a specialized buffer within the TTL family, distinct from standard logic gates by its ability to handle higher output voltages. It complements other logic families by providing a bridge between low-voltage control signals and high-voltage actuation devices.

Replacement Considerations

Cross-reference with SN7416D for surface-mount equivalents. Verify pin compatibility with SN74LS16, noting differences in drive strength and speed characteristics between standard and low-power Schottky variants.
