MC74VHC4051, MC74VHC4052, MC74VHC4053 Analog Multiplexers / Demultiplexers High-Performance Silicon-Gate CMOS The MC74VHC4051, MC74VHC4052 and MC74VHC4053 utilize silicon-gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. These analog multiplexers/demultiplexers control analog voltages that may vary across the complete power supply range (from VCC to VEE). The VHC4051, VHC4052 and VHC4053 are identical in pinout to the high-speed HC4051A, HC4052A and HC4053A, and the metal- gate MC14051B, MC14052B and MC14053B. 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 CMOS outputs; with pullup resistors they are compatible with LSTTL outputs. These devices have been designed so that the ON resistance (Ron) is more linear over input voltage than Ron of metal-gate CMOS analog switches. Fast Switching and Propagation Speeds Low Crosstalk Between Switches Diode Protection on All Inputs/Outputs Analog Power Supply Range (VCC -- VEE) = 2.0 to 12.0 V Digital (Control) Power Supply Range (VCC -- GND) = 2.0 to 6.0 V Improved Linearity and Lower ON Resistance Than Metal--Gate Counterparts Low Noise Chip Complexity: VHC4051 — 184 FETs or 46 Equivalent Gates VHC4052 — 168 FETs or 42 Equivalent Gates VH……
