Overview
The NC7SZ66M5, produced by Fairchild Semiconductor, is a low voltage single-pole/single-throw (SPST) normally open bus switch. This ultra high-speed (UHS) CMOS compatible device is designed for applications requiring minimal propagation delay and low on-resistance. It operates within a broad VCC range of 1.65 V to 5.5 V, making it versatile for various digital systems. The device features a switch enable (OE) input that controls the connection between two ports, A and B, allowing for efficient signal handling and management.
