It accepts data one bit at a time on a single input line and shifts it through the internal register stages, presenting the stored data serially on the output. This makes it a building block for expanding digital I/O, driving serial displays, or implementing delay-line functions in logic systems where parallel output is not required. ## Lifecycle and compliance It is RoHS non-compliant, which is a constraint for designs that must meet EU RoHS directives for lead-free assembly. This part is suited for legacy or military/aerospace BOMs where leaded solder processes are still specified or where a RoHS exemption applies.","metaTitle":"SNJ5491AJ shift register, serial in serial out, active","metaDescription":"SNJ5491AJ serial-in/serial-out shift register from Texas Instruments.
