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.

• Logic–Level Translator for On/Off Control and Enable Inputs

• Fast Switching and Propagation Speeds

• High ON/OFF Output Voltage Ratio

• Diode Protection on All Inputs/Outputs

• Analog Power–Supply Voltage Range (VCC – VEE) = 2.0 to 12.0 Volts

• Digital (Control) Power–Supply Voltage Range (VCC – GND) = 2.0 to

6.0 Volts, Independent of VEE

• Improved Linearity of ON Resistance

• Chip Complexity: 66 FETs or 16.5 Equivalent Gates
