TC7MBL3125CFK,TC7MBL3126CFK CMOS Digital Integrated Circuits Silicon Monolithic TC7MBL3125CFK,TC7MBL3126CFK 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: V = 1.65 to 3.6 V CC (2) ON capacitance: C = 7.5 pF Switch On (typ.) V = 3.0 V I/O CC (3) ON resistance: R = 6.5 (typ.) V = 3.0 V, V = 0 V ON CC IS (4) Power-down protection for inputs (OE, OE and I/O) (5) Package: VSSOP14 (US14) 4.
