ON Semiconductor MC74VHC1GT66DFT1 Analog Switch

The ON Semiconductor MC74VHC1GT66DFT1 is a high-speed CMOS analog switch designed to operate with a single supply voltage ranging from 2V to 6V. This versatile component is part of ON Semiconductor's VHC family, which is known for providing a robust interface between two different voltage domains in mixed-voltage applications. Its low power consumption and high-speed operation make it an ideal choice for a variety of applications, including signal gating, chopper, modulator, demodulator, and CMOS logic implementation.

Constructed with silicon gate CMOS technology, the MC74VHC1GT66DFT1 offers superior signal integrity with high noise immunity and low power dissipation. Its bidirectional switch allows signals to flow in both directions, making it a flexible solution for routing analog or digital signals in your circuit designs. The device features a high on/off output voltage ratio, high degree of linearity, and low ON resistance, which is particularly critical in low-voltage applications.

The MC74VHC1GT66DFT1 comes in a compact SOT-353 package, which is ideal for space-constrained applications. The switch is controlled by an input voltage (TTL/CMOS compatible), which enables or disables the conduction between the I/O ports. When the control input is held high, the switch is on, and signals can pass through; when the control input is low, the switch is off, isolating the I/O ports from each other.

Key features of the MC74VHC1GT66DFT1 include:

• Low power dissipation: ICC = 2μA (max) @ TA = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Low ON resistance: RON = 5Ω (max) @ VCC = 4.5V, ION = 4.5mA
• Wide operating voltage range: VCC = 2V to 6V
• Fast switching: tON = 4ns, tOFF = 3ns @ VCC = 4.5V
• Guaranteed low leakage: IIN = 1μA (max) @ TA = 25°C

With its robust performance and compact footprint, the ON Semiconductor MC74VHC1GT66DFT1 is an excellent choice for designers looking to incorporate a reliable analog switch into their projects. Whether you're working on consumer electronics, communications equipment, or industrial systems, this component offers the quality and performance you can depend on.
