SN74LS194AN3

Shift Registers Overview

The SN74LS194AN is a low-power Schottky bidirectional universal shift register manufactured by Texas Instruments. It features a single circuit with four bits of storage and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides serial-to-parallel and parallel-to-parallel counting sequences, utilizing two input lines and one output line. It exhibits a propagation delay time of 26 ns and functions reliably across an operating temperature range from 0°C to +70°C. The component is housed in a standard 16-pin PDIP package.

Shift Registers Feature Summary

• Supports synchronous parallel loading for immediate data configuration
• Enables bidirectional shifting operations including left and right shifts
• Features direct asynchronous clear functionality for rapid state reset

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Bidirectional shift register configurations
• Parallel-to-parallel data transfer systems

Shift Registers Procurement Notes

Verify the specific ordering suffix against the official Package Option Addendum to confirm the exact physical package type and manufacturing status. Ensure that the selected variant matches the required operational temperature range and packaging quantity specifications for your design requirements.

Shift Registers Selection Notes

Select this component when a low-power Schottky logic family is required for high-speed digital applications. Confirm compatibility with standard TTL logic levels and ensure the 16-pin through-hole package aligns with the target printed circuit board layout constraints.

Shift Registers Part Context

This part belongs to the SN74LS194A series of counter shift registers produced by Texas Instruments. The series includes various package options such as SOIC and military-grade variants like the SN54LS194AJ. The SN74LS194AN specifically denotes the commercial grade version in a plastic dual in-line package format.

Shift Registers Replacement Considerations

SN74LS194AD serves as a direct surface-mount alternative in the SOIC package.
