The 74AHC1G125GW,165 is a member of the NXP AHC family of high-speed CMOS logic devices. It is a 1-bit, single-pole/single-throw (SPST) high-speedCMOS analog switch with a logic-level threshold. The device features low resistance, low power dissipation, and high speed performance with highOn-state resistance and off-state leakage current.

The 74AHC1G125GW,165 is used in a variety of applications, including data communications, medical electronics, computers, and automation, to name a few. It can be used for high-speed switching of analogue and digital signals, as well as for logic level shifting, level conversion, and signal multiplexing. In addition, it can be used for video applications, such as in video switchers, matrix switches, and multiplexers.

The 74AHC1G125GW,165 is designed to work with a single supply voltage (Vcc = 5 V) and to operate either at up to 50 MHz or at up to 36 MHz with a 3V supply voltage. It features an enable/disable input (‘E’) that can be used to enable or disable the device. The enable input is active LOW; when input is LOW the device is enabled, while when it is HIGH the device is disabled. This feature greatly reduces the power consumption in static situations, such as when the switch is inactive.

The working principle of the device is based on the intrinsic characteristics of its MOSFET-based switch. The device operates with a logic-level threshold, i.e. it turns on (or turns off) when the appropriate voltage is applied to the control input. The switching time is typically less than 0.5 μs. The on-state resistance (Ron) is typically 40 ohms, while the off-state leakage current (Ioff) is typically 0.04 μA. This low leakage current and consequent low power dissipation makes the device suitable for low power applications.

The 74AHC1G125GW,165 is suitable for a range of applications that require high-speed switching of analogue and digital signals and involves level shifting, level conversion, and signal multiplexing. In particular, it can be found in a wide range of medical electronics, data communications, computers, and automation applications. It is also suitable for video applications such as video switchers and matrix switches.
