It operates from a 4.2V to 5.5V supply rail, making it a fit for 5V nominal systems with some headroom for ripple. The interface is parallel/serial — it takes a 4-bit parallel word and shifts it out as a serial stream, or the reverse, depending on the mode pin strapping. ## 28-PLCC J-Lead — footprint and rework Housed in a 28-lead PLCC with J-bend leads (package code 28-LCC J-Lead), the body measures 11.48 x 11.48 mm per the supplier device package designation. Surface-mount assembly: the J-lead footprint is standard for PLCC-28, and the part is — no tape-and-reel, so plan for tube or tray handling on the pick-and-place.","metaTitle":"SY100E446JC TR 100E 4-Bit Parallel-to-Serial Converter","metaDescription":"SY100E446JC TR 4-bit parallel-to-serial converter from the 100E series.
