N74F786N,602

Specialty Logic Overview

The N74F786N,602 is a 4-bit asynchronous bus arbiter manufactured by NXP USA Inc. in a 16-pin plastic DIP package (SOT38-4). It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C. The device features metastable-free outputs with typical propagation delays of 6.6ns and a total supply current of 55mA.

Specialty Logic Feature Summary

• Arbitrates between four asynchronous inputs on a first-come, first-served basis
• Provides separate grant outputs for each input request
• Includes an onboard four-input AND gate
• Ensures metastable-free outputs during contention

Specialty Logic Applications

• High-speed real-time arbitration applications
• Bus request management systems
• Multi-master bus control logic

Specialty Logic Procurement Notes

Verify the specific suffix '602' against official manufacturer documentation to confirm exact commercial grade specifications and packaging details. Confirm availability status as this component may be discontinued or subject to limited supply constraints.

Specialty Logic Selection Notes

Select this component for designs requiring asynchronous arbitration without inherent priority. Ensure the application utilizes active-low inputs and outputs compatible with the 74F logic family standards. Verify that the 16-pin DIP package fits the target PCB layout requirements.

Specialty Logic Part Context

This part belongs to the 74F series of high-speed TTL logic devices originally developed by Philips Semiconductors. It serves as a specialized function logic IC designed for managing multiple simultaneous requests in digital systems.

Specialty Logic Replacement Considerations

Check for direct pin-compatible equivalents from other manufacturers offering the same 74F786 functionality. Verify electrical characteristics match the original design requirements before substitution.

Specialty Logic FAQ

How does the device handle simultaneous bus requests?

If two or more BRn inputs are asserted simultaneously, one is selected at random while all BGn outputs remain high until selection is complete.

What is the function of the EN pin?

The EN pin acts as a common enable input; when low, it enables the BG0-BG3 outputs, and when high, forces them high.
