SN74AS194N

Shift Registers Overview

The SN74AS194N is a 4-bit universal shift register manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features push-pull outputs. The device is housed in a 16-pin PDIP package with a standard DIP footprint width of 0.300 inches (7.62mm). It supports bidirectional shifting, parallel loading, and serial input capabilities. The component functions as a single element with four bits per element, designed for through-hole mounting.

• Enables parallel data loading capability
• Features push-pull output structure

Shift Registers Applications

• Data storage applications
• Shift register circuits
• Parallel-to-serial conversion tasks

Shift Registers Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt, as this component may be sourced from secondary distributors or surplus channels. Confirm that the physical package matches the 16-PDIP specification and inspect pins for integrity. Ensure the operating temperature range requirements align with the specified 0°C to 70°C limit before integration into the final design.

Shift Registers Selection Notes

Select this component when a high-speed AS-series logic family is required for 4-bit shift register functionality. Consider the 16-PDIP package constraint for through-hole assembly processes. Evaluate the 4.5V to 5.5V power supply requirement against the system's available voltage rails. Verify that the push-pull output drive strength meets the load requirements of the connected circuitry.

Shift Registers Part Context

This part belongs to the Texas Instruments 74AS series, known for advanced Schottky logic technology offering higher speed than standard TTL. The SN74AS194 serves as a universal shift register variant within this family, providing versatile data manipulation capabilities. It is distinct from other 74xx series parts by its specific speed characteristics and pinout configuration optimized for shift register operations.

Shift Registers Replacement Considerations

Check for SN74AS194 variants without the 'N' suffix if surface mount packaging is acceptable. Verify compatibility with other 74AS194 equivalents from different manufacturers, ensuring pinouts and electrical specifications match exactly.
