Functional DescriptionFunctional Description Low-Voltage, Low-Power 1-Bit Dual-Supply Bus Buffer 2. 2. 2. 2. GeneralGeneralGeneralGeneral 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 V of 1.2 V, 1.5 V, 1.8 V, or 2.5 V bus and a V CCA CCB 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. 3. FeaturesFeatures 3. 3.
