The MC74HC4316A 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 HC4316A is similar in function to the metal–gate CMOS MC14016
and MC14066, and to the High–Speed CMOS HC4016A and HC4066A.
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
