Low Voltage/Low Capacitance Quad Bus Switch

The TC7MBL3125C and TC7MBL3126C are a Low Voltage/Low

Capacitance CMOS 4bit Bus Switch. The low on-resistance of the

switch allows connections to be made with minimal propagation delay

time.

The TC7MBL3125C requires the output enable (

OE

) input to be set

high to place the output into the high impedance state,whereas the

TC7MBL3126C requires the output enable (OE) input to be set low to

place the output into the high impedance.

All inputs are equipped with protection circuits against static

discharge.

Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even

destruction.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the

significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even

if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum

ratings and the operating ranges.

Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook

(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test

report and estimated failure rate, etc).
