The MM74HC4066MTC is a single-pole, double-throw (SPDT) analog switch suitable for operation from a single power supply (+3 to +15V). It is designed to be used in an analogous switch application, multiplexer application, demultiplexer application or an application requiring simultaneously enabled high-power, low-impedance paths. It is capable of operating on 3 and 15V supplies, making it an ideal choice for applications utilizing wide voltage ranges. The MM74HC4066MTC is specifically designed to exhibit low crosstalk and off-resistance, high immunity to switching noise, and low-on-state resistance.

The MM74HC4066MTC is available with a number of features that make it an ideal choice for wide range of applications. These features include a wide range of supply voltage, low input and output capacitance, low switching current, common mode and control signal range, TTL/CMOS compatible input signals and low power consumption. The MM74HC4066MTC also exhibits excellent isolation characteristics when used with PECL signals.

The analog switch utilizes dual n-channel FET transistors in a SPDT configuration. The MM74HC4066MTC is a four-channel device, with each channel providing a signal path between input and output terminal 1 and 2. The control terminals EN A and EN B are provided with dividers, allowing each of the four channels to be independently operated. When the EN A and EN B control pins are LOW, the switch is disabled, blocking current flow through the device. When either of the EN A or EN B control pins are HIGH, the corresponding switch is enabled, allowing current to flow between terminal 1 and 2.

The MM74HC4066MTC can be used as an analog switch multiplexer, a single-pole double-throw switch, a demultiplexer, or, when used in conjunction with a logic IC, as a logic buffer. In the multiplexer application, the control pins EN A and EN B select any of the 4 channels. The channels can then be used to switch current between input and output. In the single-pole double-throw application, the control pins EN A and EN B enable one switch while disabling the other. In the demultiplexer application, the control pins select any of the 4 channels, allowing current to be diverted in any desired direction. In the logic buffer application, a logic IC is used to enable the chip, allowing it to drive higher input between input and output terminals 1 and 2.

The MM74HC4066MTC is a versatile analog switch solution suitable for a wide range of applications. The advantage of the MM74HC4066MTC over other analog switch solutions is that it is available with a wide range of supply voltage, low switching current, common mode and control signal range, and it has low input and output capacitance values. Additionally, it has good immunity to switching noise, and it works well with both TTL/CMOS compatible inputs.
