74AHC2G125DC,125 is a quad bilateral switch designed for high-speed logic level translation and signal switching applications. The device operates from 1.65V to 5.5V and uses advantages of advanced silicon-gate CMOS technology. 74AHC2G125DC,125 offers high speed performance of tPD (propagation delay) of 6.5 ns, at 5V supply and tr of 5.3ns, at 5V supply.

Application Field

74AHC2G125DC,125 can be used in numerous applications, such as multiplexers, analog and digital signal routing, multiple voltage level digital signal level translation, analog and digital signal level shifting and switching, and high-speed data transmission systems.

In addition, 74AHC2G125DC,125 is particularly attractive for low power, high speed systems; 3V systems; and applications where large capacitive loads are present. For example, these can include PC/104 bus structures, digital switching/level clamping, SMPTE259M compatible serial links, Gb/s level signal buffering and routing, and more.

Working Principle

74AHC2G125DC,125 operates in either transmission or reception mode. In the transmission mode, each switch connects the VDD side logic terminal to the VSS side logic terminal. When the switch is off, the logic high is near VDD, and the logic low is near VSS. In the reception mode, each switch connects the VDD side logic terminal to the VSS side logic terminal.

74AHC2G125DC,125 circuitry has two input pins(A,B) and two output pins (Y,Z). To control the two switches, the two input pins are connected to logic signals. Depending on the logic state, the two switches will be closed or opened. For example, when A and B are both logic high, the two switches are open and the two output terminals (Y,Z) will be in High Impedance (HI-Z) state.

The 74AHC2G125DC,125 also has two power supply pins, VSS and VDD. VSS is the ground voltage and VDD is the power supply voltage. The VSS pin must be connected to the GND rail of the system, while the VDD pin must be connected to VDD pin of the system.

In conclusion, 74AHC2G125DC,125 is a quad bilateral switch designed for high speed logic level translation and signal switching applications. The device has two input pins, two output pins and two power supply pins. It can be used in numerous applications such as multiplexers, analog and digital signal routing, signal level translation, switching, and high-speed data transmission systems. It has features such as high speed performance and low power consumption.
