The HEF4053BT is a triple 2-channel analogue multiplexer/demultiplexer with a common enable input (E). Each multiplexer/demultiplexer has two independent inputs/outputs (Y0 and Y1), a common input/output (Z), and select inputs (Sn). Each also contains two-bidirectional analogue switches, each with one side connected to an independent input/output (Y0 and Y1) and the other side connected to a common input/output (Z).
Some examples of applications for the HEF4053BT are:
1. Analogue multiplexing and demultiplexing. 2. Digital multiplexing and demultiplexing. 3. Signal gating.
The CoolSET®-F3R jitter series (ICE3BR0665J) is the latest version of CoolSET®-F3. It targets for the Off-Line battery adapters and low cost SMPS for lower power range such as application for DVD R/W, DVD Combi, Blue ray DVD player, set top box, etc. Besides inherited the outstanding performance of the CoolSET®-F3 in the BiCMOS technology, active burst mode, auto-restart protection, propagation delay compensation, etc., CoolSET®-F3R series has some new features such as built-in soft start time, built-in blanking window, built-in frequency jitter, soft gate driving, etc. In case a longer blanking time is needed for high load application, a simple addition of capacitor to BA pin can serve the purpose. Furthermore, an external auto-restart enable feature can provide extra protection when there is a need of immediate stop of power switching.
