| TC7MA257FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MA257FK Low Voltage Quad 2-Channel Multiplexer with 3.6 V Tolerant Inputs and Outputs The TC7MA257FK is a high performance CMOS multiplexer. Designed for use in 1.8 , 2.5 or 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. It consists of four 2-input digital multiplexers with common SELECT and OUTPUTENABLE ( OE ). If OE is set high the outputs are held in a high-impedance state. The SELECT decoding determines whether the A or B Weight: 0.02 g (typ.) inputs get routed to their corresponding Y outputs. All inputs are equipped with protection circuits against static discharge. Features * * Low voltage operation: VCC = 1.8~3.6 V High speed operation: tpd = 3.0 ns (max) (VCC = 3.0~3.6 V) tpd = 4.0 ns (max) (VCC = 2.3~2.7 V) tpd = 8.0 ns (max) (VCC = 1.8 V) 3.6 V tolerant inputs and outputs. Output current: IOH/IOL = 24 mA (min) (VCC = 3.0 V) IOH/IOL = 18 mA (min) (VCC = 2.3 V) IOH/IOL = 6 mA (min) (VCC = 1.8 V) Latch-up performance: 300 mA ESD performance: Machine model > 200 V Human body model > 2000 V Package: VSSOP (US16) Power down protection is provided on all inputs and outputs. Supports live insertion/withdrawal (*) *: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. * * * * * * * 000630EBA1 * TOSHIBA is continually working to improve the quality and reliability of its products.
