| TC7MA157FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MA157FK Low Voltage Quad 2-Channel Multiplexer with 3.6 V Tolerant Inputs and Outputs The TC7MA157FK 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 strobe inputs. When the ST input is held "H" level, selection of data is inhibited and all the outputs become "L" level. The SELECT Weight: 0.02 g (typ.) decoding determines whether the A or B 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 = 3.5 ns (max) (VCC = 2.3~2.7 V) tpd = 7.0 ns (max) (VCC = 1.8 V) 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. * * * * * 000630EBA1 * TOSHIBA is continually working to improve the quality and reliability of its products.
