Product details

4-bit bidirectional shift register — what it does

The SN74S194N is a 4-bit bidirectional universal shift register from the 74S Schottky TTL family, designed for parallel-in/parallel-out operation. It can shift data left or right, load parallel data, or hold, giving it the flexibility for register-based storage, serial-to-parallel conversion, and barrel-shifter building blocks in TTL logic systems.

RoHS non-compliant — plan your solder profile

However, it is RoHS non-compliant (lead-bearing finish), so it requires a tin-lead solder process. If your assembly line is RoHS-only, you will need an exemption or a waiver to use this part.

Bulk packaging — handling note

For small-run or rework, bulk is fine, but for automated pick-and-place you will need to transfer to a feeder-compatible carrier. ESD-safe handling is assumed — the bulk format lacks the anti-static shielding of a sealed reel.

Frequently asked questions

What is the datasheet for SN74S194N?

Design engineers need to verify electrical specs and pinout before using the part in a circuit.

Where can I buy SN74S194N?

Buyers need to quickly locate a distributor with stock to fill a BOM line.

What is the price of SN74S194N?

Sourcing buyers compare costs across suppliers for budget planning.

What are the alternatives to SN74S194N?

Engineers and procurement look for drop-in replacements or equivalents if the part is unavailable or for second-sourcing.

Is SN74S194N active or obsolete?

Brokers and buyers need lifecycle status to avoid last-time buys or incompatible redesigns.

What is the pinout of SN74S194N?

Maintenance techs and designers need pin-to-pin mapping for board repair or layout.
