TC7MB3125CFK-EL(M)

Overview

The TC7MB3125CFK-EL(M) is a low capacitance quad bus switch manufactured by Toshiba Semiconductor and Storage. It operates within a power supply voltage range of 4.0 to 5.5 V. The device features an on-resistance (RON) of 3 Ω typical at VCC=4.5 V with VIS=0 V, and an on-capacitance (CI/O) of 7 pF typical at VCC=5 V. It includes power-down protection for inputs and is compatible with TTL outputs for control inputs.

Feature Summary

Low ON-resistance allows connections with minimal propagation delay time
Power-down protection provided for OE, OE, and I/O inputs
Compatible with TTL outputs for control inputs
Inputs equipped with protection circuits against static discharge

Applications

General-purpose bus switching applications requiring low capacitance
Connecting buses in systems operating at 4.0 to 5.5 V
Interfaces requiring compatibility with TTL output levels

Procurement Notes

Verify the specific package type matches the required footprint, as the TC7MB3125C series is available in TSSOP14, VSSOP14, and VQON16 packages. Confirm that the ordering suffix corresponds to the desired packaging format. Ensure the design accounts for the 4.0 to 5.5 V operating voltage range and check RoHS compliance status through official manufacturer channels before finalizing procurement.

Selection Notes

Select this component when a low capacitance quad bus switch is needed for 5 V logic systems. The TC7MB3125C variant requires the OE input to be set high for high impedance, whereas the TC7MB3126C requires it to be set low. Consider the RON and CI/O values for signal integrity requirements. Verify that the application does not exceed the absolute maximum ratings for voltage or current.

Part Context

This part belongs to the TC7MB3125C/TC7MB3126C family of low capacitance quad bus switches from Toshiba. These CMOS digital integrated circuits are designed for low on-resistance and low capacitance performance. The family includes variants with different enable logic polarities and package options such as TSSOP14, VSSOP14, and VQON16.
