TC7MB3125CFT-EL(M)

Overview

The TC7MB3125CFT-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 outputs, ensuring compatibility with TTL control inputs.

Feature Summary

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

Applications

• Connecting data buses in systems requiring low capacitance
• Interfacing between components operating at 4.0V to 5.5V supply voltages
• Applications requiring high ESD performance and power-down protection

Procurement Notes

Verify the specific package type required, as the datasheet lists TSSOP14, VSSOP14, and VQON16 options. Confirm that the application environment stays within the specified operating temperature range of -40°C to +85°C. Ensure that unused control pin inputs are tied to either VCC or GND during implementation to maintain normal operation.

Selection Notes

Select this component when a low capacitance quad bus switch is needed for 4.0V to 5.5V applications. The TC7MB3125C requires the output enable input to be set high to place the output into the high impedance state. Consider the low on-resistance for minimizing signal propagation delays in high-speed digital interfaces.

Part Context

This part belongs to the TC7MB3125C/TC7MB3126C series of low capacitance quad bus switches from Toshiba. The TC7MB3125C specifically uses a high-active output enable logic, contrasting with the TC7MB3126C which uses a low-active enable. Both share similar electrical characteristics but differ in control logic polarity.
