TC7MZ4051

      This is the description about TC7MZ4051 and TC7MZ4052 of the TOSHIBA CMOS Digital Integrated Circuit, Silicon Monolithic. The TC7MZ4051/4052 are high-speed, low-voltage drive analog multiplexer/demultiplexers using silicon gate CMOS technology. In 3 V and 5 V systems these can achieve high-speed operation with the low power dissipation that is a feature of CMOS. The TC7MZ4051/4052 offer analog/digital signal selection as well as mixed signals. The 4051 has an 8-channel configuration, the 4052 has an 4-channel * 2 configuration, and the 4053 has a 2-channel * 3 configuration. The switches for each channel are turned ON by the control pin digital signals. Although the control signal logical amplitude (VCC - GND) is small, the device can perform large-amplitude (VCC - VEE) signal switching. For example, if VCC = 3 V, GND = 0 V, and VEE = -3 V, signals between -3 V and +3 V can be switched from the logical circuit using a single 3 V power supply.
      Here are the features of TC7MZ4051: Low ON resistance:   Ron = 22 ? (typ.) (VCC - VEE = 3 V), Ron = 15 ? (typ.) (VCC - VEE = 6 V); High speed: tpd = 3 ns (typ.) (VCC = 3.0 V); Low power dissipation: ICC = 4 A (max) (Ta = 25°C); Input level:   VIL = 0.8 V (max) (VCC = 3 V), VIH = 2.0 V (min) (VCC = 3 V); Power down protection is provided on all control inputs; Pin and function compatible with 74HC4051/4052.
      The maximum ratings are these. Power supply voltage is from -0.5 to 7.0V. Control input voltage is from -0.5 to 7.0V. Switch I/O voltage is from VEE - 0.5 to VCC + 0.5V. Input diode current is -20mA. I/O diode current is ±20mA. Switch through current is ±25mA. DC VCC or ground current is ±50mA. Power dissipation PD is 180mW. Storage temperature is from -65 to 150°C.
