TC7MBL3245CFK(EL)

Overview

The TC7MBL3245CFK is a low-voltage, low-capacitance CMOS octal bus switch. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature from -40 °C to +85 °C. The device features a typical on-resistance of 6.5 Ω at 3.0 V and a typical ON capacitance of 7.5 pF. Power-down protection is included for inputs. The output enable (OE) input controls the high-impedance state when set high. The component is housed in a VSSOP20 (US20) package.

Feature Summary

• Low-voltage operation with power-down protection for OE and I/O inputs
• Low ON resistance enabling minimal propagation delay
• Low ON capacitance suitable for high-speed signal switching
• Built-in static discharge protection circuits on all inputs

Applications

• Connecting data buses in low-voltage systems
• Level shifting between different voltage domains
• Signal routing in portable electronic devices

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status through official Toshiba documentation before procurement. Ensure design parameters align with the absolute maximum ratings provided in the datasheet to maintain reliability. Check for any recent revisions to the product specifications that may affect integration.

Selection Notes

Select this component for applications requiring bidirectional data transfer with low insertion loss. The low ON capacitance makes it suitable for high-frequency signals. Ensure the system voltage falls within the 1.65 V to 3.6 V range. Consider the VSSOP20 package constraints for PCB layout and thermal management during the selection process.

Part Context

This part belongs to the TC7MBL series of low-voltage bus switches manufactured by Toshiba Semiconductor and Storage. It is designed as a silicon monolithic CMOS digital integrated circuit. The series focuses on providing efficient signal switching with minimal power consumption and signal degradation in compact form factors.

Replacement Considerations

Consult the official Toshiba replacement guide or contact sales representatives for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' bus switches without verifying pinout and electrical characteristics.
