Product details

What the SN74LS194AN is and where it fits

The Texas Instruments SN74LS194AN is a 4-bit bidirectional universal shift register from the 74LS low-power Schottky logic family. It can shift data left or right, load parallel data, or hold its state — all controlled by two mode-select pins. Typical applications include serial-to-parallel data conversion, digital delay lines, and state registers in 5V TTL-based control systems, industrial logic controllers, and legacy test equipment.

Lifecycle and sourcing reality

The SN74LS194AN carries an Active lifecycle status and is ROHS3 compliant. For a BOM line that needs a 5V bidirectional shift register in a DIP package, this part is a straightforward, available choice.

Frequently asked questions

What is the function of the SN74LS194AN?

It is a 4-bit bidirectional universal shift register. It is used for serial-to-parallel conversion, digital delay, and state storage in 5V TTL logic systems.

What are the alternatives for the SN74LS194AN?

Within the 74LS family, the SN74LS194AN is the standard DIP version. A surface-mount alternative is the SN74LS194AD (SOIC-16), which shares the same logic function but in a smaller footprint for boards that avoid through-hole. Both are active parts from TI.
