1. Functional Description
• Low-Voltage, Low-Capacitance Quad Bus Switch
2. General
The TC7MBL3125CFK and TC7MBL3126CFK 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 TC7MBL3125CFK requires the output enable (OE) input to be set high to place the output into the high impedance state, whereas the TC7MBL3126CFK 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.
3. Features
(1) Operating voltage: VCC = 1.65 to 3.6 V (2) ON capacitance: CI/O = 7.5 pF Switch On (typ.) @VCC = 3.0 V (3) ON resistance: RON = 6.5 Ω (typ.) @VCC = 3.0 V, VIS = 0 V (4) ESD performance: MM ≥ ±200 V, HBM ≥ ±2000 V (5) Power-down protection for inputs (OE, OE and I/O) (6) Package: VSSOP14 (US14)

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).

Note 1: All typical values are at Ta = 25 �. Note 2: Measured by the voltage drop between A and B pins at the indicated current through the switch. On-resistance
is determined by the lower of the voltages on the two (A or B) pins.
