74F194SCX

Overview

The Fairchild Semiconductor 74F194SCX is a high-speed, 4-bit bidirectional universal shift register belonging to the F/FAST series. It operates with TTL logic levels and features true outputs in a 16-lead Small Outline Integrated Circuit (SOIC) package. The device supports asynchronous master reset and a hold mode. It enables fully synchronous serial or parallel data transfers, facilitating serial-serial, shift left, shift right, serial-parallel, parallel-serial, and parallel-parallel data register transfers.

Feature Summary

• Supports bidirectional shifting operations including left and right shifts
• Enables multiple data transfer modes such as serial-parallel and parallel-parallel
• Includes an asynchronous master reset function for immediate initialization

Applications

• Serial-serial data register transfers
• Shift left and shift right operations
• Parallel-parallel data register transfers

Procurement Notes

Verify that the ordering code includes the 'X' suffix to confirm the tape and reel packaging variant. Ensure compatibility with the 16-lead SOIC physical footprint. Confirm the manufacturer origin matches Fairchild specifications for the F/FAST series performance characteristics.

Selection Notes

Select this component when a high-speed 4-bit bidirectional shift register is required. It is suitable for applications needing versatile data transfer modes like serial-to-parallel conversion. The F/FAST series offers speed advantages over standard logic families while maintaining TTL input compatibility.

Part Context

This part is a specific packaged version of the 74F194 universal shift register. The 'SC' indicates the 16-lead SOIC package, while the 'X' suffix denotes tape and reel availability. It belongs to the broader 74F logic family designed for high-speed digital applications requiring reliable sequential data handling.

Replacement Considerations

Check for other 74F194 variants from different manufacturers that offer identical pinouts and electrical characteristics. Verify that any substitute maintains the same bidirectional functionality and asynchronous reset capabilities.
