74F350PC

Overview

The Fairchild Semiconductor 74F350PC is a 4-bit barrel shifter belonging to the F/FAST series. It operates on TTL logic with a supply voltage range of 4.5V to 5.25V and supports three-state outputs. The device features barrel shifting capabilities and includes three linking inputs for expansion, allowing integration into larger systems. It is housed in a 20-pin plastic leaded chip carrier (LCC-20) package.

Feature Summary

• Supports barrel shifting operations within a 4-bit configuration
• Includes three linking inputs designed for system expansion
• Provides three-state output capability for bus-oriented applications

Applications

• Bus-oriented data routing systems
• Microprocessor interface circuits
• Communication systems requiring data shifting

Procurement Notes

Verify the specific package type against project requirements, as datasheets indicate both 16-pin DIP and 20-pin LCC variants exist for this part number across different manufacturers. Confirm that the 20-pin LCC version aligns with the intended footprint. Check for obsolete status or lifecycle changes from the original manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a compact 4-bit barrel shifter with expansion capabilities is required for TTL-based designs. Ensure the design accommodates the specific pinout of the 20-pin LCC package if that variant is sourced. Verify compatibility with the 4.5V to 5.25V operating voltage range and three-state bus requirements.

Part Context

The 74F350 is part of the F/FAST series of high-speed logic devices produced by Fairchild Semiconductor. This series utilizes advanced Schottky technology to provide improved switching performance with reduced power dissipation compared to standard Schottky counterparts. The device serves as a specialized shift register variant focused on barrel shifting functions.
