7416PC

Buffers, Drivers, Receivers, Transceivers Overview

The National Semiconductor 7416PC is a hex inverting buffer and driver featuring high-voltage open-collector outputs. It operates on a nominal 5 V supply with a range of 4.75 V to 5.25 V. The device contains six independent inverters within a 14-lead plastic dual-in-line package (PDIP). Key electrical parameters include a maximum propagation delay of 23 ns at nominal voltage, a maximum low-level output current of 40 mA, and a maximum supply current of 51 mA. It supports frequencies up to 35 MHz and functions within an operating temperature range of 0°C to 70°C.

Buffers, Drivers, Receivers, Transceivers Applications

• Driving high-voltage indicators or lamps.
• Interfacing TTL logic with non-TTL loads.
• General-purpose digital signal inversion in industrial control systems.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix 'PC' corresponds to the 14-lead PDIP package. Ensure the component meets the required operating temperature range and voltage specifications for your application environment before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-voltage open-collector switching is required for TTL signals. The 40 mA sink capability allows direct driving of relays or LEDs without additional transistors. Consider the 23 ns propagation delay for timing constraints. Verify package availability and lead time if sourcing from legacy distributors.

Buffers, Drivers, Receivers, Transceivers Part Context

The 7416 series belongs to the standard 7400 family of bipolar TTL logic devices. The 'N' prefix often denotes National Semiconductor variants, while 'SN' denotes Texas Instruments. This specific part represents a legacy component widely used in older digital designs requiring high-voltage output stages.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Texas Instruments SN7416 is the primary verified equivalent. Other manufacturers may offer compatible parts under the generic 7416 designation, but pinout and electrical characteristics must be verified against the original datasheet.
