MC74LVXT4051 Analog Multiplexer/ Demultiplexer High–Performance Silicon–Gate CMOS The MC74LVXT4051 utilizes silicon–gate CMOS technology to achieve fast propagation delays, low ON resistances, and low leakage currents. This analog multiplexer/demultiplexer controls analog voltages that may vary across the complete power supply range (from VCC to VEE). The LVXT4051 is similar in pinout to the LVX8051, the HC4051A, and the metal–gate MC14051B. The Channel–Select inputs determine which one of the Analog Inputs/Outputs is to be connected, by means of an analog switch, to the Common Output/Input. When the Enable pin is HIGH, all analog switches are turned off. The Channel–Select and Enable inputs are compatible with standard TTL levels. These inputs are over–voltage tolerant (OVT) for level translation from 6.0 V down to 3.0 V. This device has been designed so the ON resistance (RON) is more linear over input voltage than the RON of metal–gate CMOS analog switches and High–Speed CMOS analog switches. • • • • • • MARKING DIAGRAMS 16 9 LVXT4051 AWLYYWW SO–16 D SUFFIX CASE 751B 1 8 16 9 LVXT 4051 AWLYWW TSSOP–16 DT SUFFIX CASE 948F 1 8 Select Pins Compatible with TTL Levels Fast Switching and Propagation Speeds 16 Low Crosstalk Between Switches Analog Power Supply Range (VCC – VEE) = 3.0 V to 3.0 V Digital (Control) Power Supply Range (VCC – GND) = 2.5 to 6.0 V Improved Linearity and Lower ON Resistance Than Metal–Gate, HSL, or VHC Counterparts Low Noise • • Designed to Operate on a Single Supply with VEE = GND, or Using • http://onsemi.com Split Supplies up to 3.0 V Break–Before–Make Circuitry LVXT4051 ALYW SO EIAJ–16 M SUFFIX CASE 966 A L, WL Y, YY W, WW 9 1 8 = Assembly Location = Wafer Lot = Year = Work Week ORDERING INFORMATION Device Semiconductor Components Industries, LLC, 2002 January, 2002 – Rev. 3 1 Package Shipping MC74LVXT4051D SO–16 48 Units/Rail MC74LVXT4051DR2 SO–16 2500 Units/Reel MC74LVXT4051DT TSSOP–16 96 Units/Rail MC74LVXT4051DTR2 TSSOP–16 2500 Units/Reel MC74LVXT4051M SO EIAJ–16 48 Units/Rail MC74LVXT4051MEL SO EIAJ–16 2000 Units/Reel Publication Order Number: MC74LVXT4051/D MC74LVXT4051 FUNCTION TABLE VCC X2 X1 X0 X3 A B C 16 15 14 13 12 11 10 9 1 X4 2 X6 3 X 4 X7 Control Inputs Enable C L L L L L L L L H L L L L H H H H X 5 6 7 8 X5 Enable VEE GND Figure 1.

Although used here, balanced supplies are not a requirement. The only constraints on the power supplies are that: VEE – GND = 0 to 6 volts VCC – GND = 2.5 to 6 volts VCC – VEE = 2.5 to 6 volts and VEE GND When voltage transients above VCC and/or below VEE are anticipated on the analog channels, external Germanium or Schottky diodes (Dx) are recommended as shown in Figure 22. These diodes should be able to absorb the maximum anticipated current surges during clipping. The Channel Select and Enable control pins should be at VCC or GND logic levels. VCC being recognized as a logic high and GND being recognized as a logic low. In this example: VCC = 5 V = logic high GND = 0 V = logic low The maximum analog voltage swing is determined by the supply voltages VCC and VEE. The positive peak analog voltage should not exceed VCC. Similarly, the negative peak analog voltage should not go below VEE. In this example, the difference between VCC and VEE is five volts. Therefore, using the configuration of Figure 21, a maximum analog signal of five volts peak–to–peak can be controlled. Unused analog inputs/outputs may be left floating (i.e., not connected).
