Quad Analog Switch/Multiplexer/Demultiplexer with Separate Analog and Digital Power Supplies

High–Performance Silicon–Gate CMOS

The MC74HC4316 utilizes silicon–gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF–channel leakage current. This bilateral switch/multiplexer/demultiplexer controls analog and digital voltages that may vary across the full analog power–supply range (from VCC to VEE).

The HC4316 is similar in function to the metal–gate CMOS MC14016 and MC14066, and to the High–Speed CMOS HC4016 and HC4066. Each device has four independent switches. The device control and Enable inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The device has been designed so that the ON resistances (RON) are much more linear over input voltage than RON of metal–gate CMOS analog switches. Logic–level translators are provided so that the On/Off Control and Enable logic–level voltages need only be VCC and GND, while the switch is passing signals ranging between VCC and VEE. When the Enable pin (active–low) is high, all four analog switches are turned off.
