Product details

4-bit shift register — what it does on the board

The Texas Instruments SN54LS194AJ is a 4-bit bidirectional universal shift register from the 54LS logic family. It handles parallel load, shift left, shift right, and hold operations under a single supply rail — common in register-file buffers, serial-to-parallel conversion, and state-machine storage in industrial and military-grade digital logic.

Active lifecycle — no last-time-buy pressure

The SN54LS194AJ carries an Active product status.

Bulk shipment — what to expect at receiving

For a DIP-package part like this, Bulk is the norm for through-hole assembly. Plan for manual or tube-fed insertion; no reel changeover needed.

Frequently asked questions

Is the SN54LS194AJ obsolete?

No. The SN54LS194AJ is listed as Active in the lifecycle record. There is no end-of-life notice or last-time-buy schedule on file.

What is the SN54LS194AJ used for?

Typical applications include parallel-to-serial conversion, serial-to-parallel conversion, register-file buffering, and state-machine storage in digital logic systems.

What is the difference between the SN54LS194AJ and the 74LS194A?

The SN54LS194AJ is the 54-series (military temperature range) version, while the 74LS194A is the commercial/industrial temperature range version. The 54-series parts are specified over the full -55 to +125 °C range and are often used in defence, aerospace, and high-reliability applications.
