TC7MBL3125CFK(EL)

Overview

The TC7MBL3125CFK(EL) is a low-voltage, low-capacitance CMOS quad bus switch manufactured by Toshiba. 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 (RON) of 6.5 Ω at 3.0 V and a maximum of 27 Ω across the full voltage range. Input capacitance is typically 4 pF, while switch terminal ON-capacitance is 7.5 pF. Power-down protection is included for all inputs. The component is housed in a VSSOP-14 package.

Feature Summary

• Low-voltage operation with power-down protection for OE and I/O inputs
• Low on-resistance enabling minimal propagation delay
• Low input and ON-state capacitance for high-speed signal integrity

Applications

• Portable equipment requiring low power consumption
• High-speed data transmission lines
• Battery-powered systems

Procurement Notes

Verify that the specific ordering suffix matches the required packaging format. Confirm RoHS compliance status through official manufacturer channels prior to integration. Ensure design adheres to absolute maximum ratings to prevent performance deterioration or destruction. Review the Toshiba Semiconductor Reliability Handbook for derating concepts and handling precautions before finalizing procurement specifications.

Selection Notes

Select this component when low capacitance and low on-resistance are critical for maintaining signal integrity in high-speed applications. The TC7MBL3125CFK requires the output enable input to be set high to place outputs into a high impedance state, distinguishing it from complementary variants like the TC7MBL3126CFK which activates high impedance at a low logic level. Ensure control inputs are tied to VCC or GND if unused.

Part Context

This part belongs to the TC7MBL series of low-voltage/low-capacitance CMOS digital integrated circuits. It functions as a 4-bit bidirectional bus switch designed for connecting two ports with minimal delay. The device is part of Toshiba's portfolio aimed at portable and battery-operated electronic devices where power efficiency and signal speed are prioritized.

Replacement Considerations

The TC7MBL3126CFK serves as a functional alternative within the same series but utilizes inverted logic for the output enable function.
