The LTC1563-2CGN#PBF is an analog switch and level translator integrated circuit (IC) manufactured by Linear Technology. It is a dual CMOS switch that operates within a supply voltage range of 1.25V to 5.5V, making it suitable for low voltage applications.
One of the key features of the LTC1563-2CGN#PBF is its ability to translate and level shift signals between different logic levels. It can accept logic inputs from TTL, CMOS, or ground-referenced signals, and convert them to a higher or lower voltage level as required. This makes it ideal for interfacing between devices operating at different voltage levels.
The IC includes two independent switches, labeled A and B. Each switch has its own enable input, allowing the user to control their operation independently. When enabled, the switches offer a low on-resistance, typically around 7Ω, minimizing signal distortion and loss. The low on-resistance also facilitates the transmission of higher frequency signals.
Furthermore, the LTC1563-2CGN#PBF features a break-before-make switching action, which ensures that both switches are in an open state during the transition from one state to another. This eliminates the risk of signal shorting and avoids potential damage to connected devices, enhancing the reliability of the system.
To prevent latch-up and improve signal integrity, the IC incorporates an advanced substrate triggering (ST) structure
