Renesas offers a 2.5/3.3V and 5V bus switch family known as QuickSwitch®. The QuickSwitch technology was created to meet unique customer needs by providing cost-effective performance-enhanced solutions. These devices provide low ON-resistance and high-speed switching without adding propagation delay, ground bounce noise, or static power dissipation. Renesas offers bus switches with different functions, including multiplexer, demultiplexer, analog switch, and rail-to-rail switching products. These are ideal for bidirectional interfaces between mixed-supply buses, and in applications that require isolation, protection and voltage translation. These switches are available in octal, double density, and wide bus configurations. Renesas analog bus switch products are ideal for multimedia PCs and video conferencing capabilities.
Renesas’ rich portfolio of bus switches includes:
A bus switch IC is an array of high-speed, low-resistance CMOS switches used to relay a group of signals known as a signal bus. Sometimes known as a bilateral switch or analog switch, these bus switch ICs offer the same basic function as a mechanical relay, but have no moving parts and offer much better performance.
The control input to the device is typically a digital signal that switches between the positive and negative supply voltages, with the more positive voltage switching the device on and the more negative switching the device off.
