TC7SPN334L6X

CMOS Digital Integrated Circuits Silicon Monolithic TC7SPN334L6X TC7SPN334L6X 1. Functional Description Low-Voltage, Low-Power 1-Bit Dual-Supply Bus Buffer 2. General The TC7SPN334L6X is a CMOS high-speed single-bit bus buffer designed to interface between two subsystems operating at different voltage levels between 1.1 V and 3.6 V. Its input and output provide overvoltage tolerance and accept up to 3.6 V in power-down mode (power-down protection). The TC7SPN334L6X dual-supply bus buffer operates with a VCCA of 1.2 V, 1.5 V, 1.8 V, or 2.5 V bus and a VCCB of 1.8 V, 2.5 V or 3.3 V. It is suitable for single-bit interfacing. The A input interfaces with the 1.2 V, 1.5 V, 1.8 V or 2.5 V bus, and the B output interfaces with the 1.8 V, 2.5 V, 3.3 V bus. All inputs are equipped with protection circuits against static discharge or transient excess voltage. 3. Features (1) Level converter for interfacing 1.2 V to 1.8 V, 1.2 V to 2.5 V, 1.2 V to 3.3 V, 1.5 V to 2.5 V, 1.5 V to 3.3 V, 1.8 V to 2.5 V, 1.8 V to 3.3 V or 2.5 V to 3.3 V system.
