The TC7MBD3245AFK is an SMD IC from Toshiba that acts as an 8-bit dual-supply bus switch with bidirectional level shifting. It is widely used for interfacing between devices with different operating voltage levels in digital systems. Key Specifications: Functionality: Bidirectional Level Shifting: Translates signals between two voltage levels. Bus Switch: Facilitates communication between two buses by acting as an active, low-resistance switch. Voltage Levels: VccA: Low-voltage side supply (1.65 V to 3.6 V). VccB: High-voltage side supply (2.3 V to 5.5 V). ON Resistance (RON): Typical RON: ~5 Ω. Ensures low signal distortion and high-speed transmission. Control Logic: Includes enable pins to turn the bus switch on or off as needed. Operating Speed: High-speed operation suitable for fast data communication. ESD Protection: Built-in electrostatic discharge protection for robust operation. Package Details: Package Type: SSOP20 (Shrink Small Outline Package). 20 pins, compact SMD design. Dimensions: Body Width: ~5.3 mm. Pin Pitch: 0.65 mm. Material Composition: Encapsulation: Epoxy resin to provide environmental protection. Lead Plating: Tin for solderability and corrosion resistance. Applications: Voltage level translation in multi-voltage systems. Signal switching in digital systems, including microcontrollers and FPGAs. Data bus control in portable electronics, consumer devices, and industrial systems. Pinout Overview: A and B Ports: Interface for voltage-level translation. Control Pins: Enable and control the switch functionality. Refer to the datasheet for a detailed pin configuration and operational characteristics. Additional Notes: Ensure proper PCB layout for thermal dissipation and reliable signal transmission.
