TC7MB3245CFT-EL(M)

Overview

The TC7MB3245CFT-EL(M) is an octal bus switch manufactured by Toshiba Semiconductor and Storage. It provides eight bits of high-speed TTL-compatible bus switching in a standard '245 device pinout. The device operates within a supply voltage range of 4.5 to 5.5 V. Key electrical characteristics include a maximum propagation delay (tpd) of 0.25 ns and a typical on-state resistance (RON) of 5 Ω. ESD performance meets machine model standards of ≥ ±200 V and human body model standards of ≥ ±2000 V.

Feature Summary

• Provides eight bits of high-speed TTL-compatible bus switching
• Features low on-state resistance for minimal propagation delay
• Includes protection circuits against static discharge on all inputs

Applications

• High-speed data transmission between busses
• TTL-compatible signal routing
• Low-resistance connection switching

Procurement Notes

Verify the specific ordering suffixes, such as EL or M, against official Toshiba documentation to confirm package type and reel specifications. Ensure compatibility with the required operating temperature range of -40 to 85 °C. Confirm that the design adheres to the absolute maximum ratings provided in the datasheet to prevent device deterioration.

Selection Notes

Select this component when a standard '245 pinout is required for an octal bus switch application. It is suitable for systems requiring high-speed operation with low propagation delay. Consider the 5 Ω typical on-resistance for applications sensitive to signal loss. Verify that the 4.5 to 5.5 V supply voltage aligns with the system power architecture.

Part Context

This part belongs to the TC7MB3245 series of CMOS digital integrated circuits. It is functionally equivalent to FST/CBT 3245 devices. The series is designed for use in 5 V environments, offering high-speed performance while maintaining low power dissipation typical of CMOS technology.

Replacement Considerations

The datasheet notes functional equivalence to FST/CBT 3245 types. Verify pin compatibility and electrical parameters before substituting with other manufacturers' octal bus switches.
