74F350SC

Overview

The Fairchild Semiconductor 74F350SC is a 4-bit barrel shifter belonging to the F/FAST logic series. It features TTL-compatible inputs and 3-state outputs housed in a 20-pin PLCC package. The device supports barrel shifting operations and includes three linking inputs designed for system expansion. It operates within standard industrial temperature ranges and utilizes plastic epoxy packaging.

Feature Summary

• Supports barrel shifting functionality with dedicated linking inputs for cascading multiple units
• Features 3-state outputs compatible with bus-oriented systems
• TTL input levels ensure compatibility with standard logic families

Applications

• Data routing in microprocessor-based systems
• Communication interface circuits requiring bit manipulation
• Memory subsystem data path control

Procurement Notes

Verify the specific package variant, as the SC suffix typically denotes a Plastic Leaded Chip Carrier (PLCC). Confirm RoHS compliance status and manufacturing origin against current datasheets. Ensure the ordering code matches the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select this component when a compact 4-bit shift capability is needed within an F/FAST speed grade. The 3-state output allows direct connection to shared data buses without external tri-state buffers. Consider the PLCC package constraints for PCB layout if surface-mount space is limited but through-hole is not preferred.

Part Context

This part belongs to the Fairchild 74F series, known for high-speed Schottky TTL performance. It serves as a specialized data manipulation element distinct from standard buffers or flip-flops. The F/FAST series bridges the gap between standard TTL speed and low-power CMOS consumption.
