Water meter / Gas meter communication circuit

Littelfuse has introduced the PLED family with ultra-low holding current (only 21mA), which enables ballast drivers widely used in fluorescent tube outputs to be compatible with modern LED strings or tubes for replacement. Therefore, there is no need to discard ballasts that can still work when replacing fluorescent tubes with LED strings or lamps.

Semtech Corporation (Nasdaq:SMTC), a leading supplier of high-performance analog and mixed-signal semiconductor products and advanced algorithms, has announced the launch of its newest product line of its RClamp® low-capacity surge protection product platform. This new four-wire transient voltage suppressor (TVS) array provides high-inrush, low-capacitance transient voltage protection and features a device layout that is easy to layout. The new RClamp2594N device also minimizes capacitive loading on high-speed interfaces as a product optimized for telecommunications and industrial data interfaces to provide excellent protection against dangerous transient voltages.
