The 74AHCT240D-Q100J is a member of the renowned ‘74’ series of low-skew logic buffers, drivers, receivers, and transceivers. It is a high-speed logic device optimized for use in applications where fast settling time, low power consumption, and precision timing are essential. It is ideal for driving high-speed memory devices, as well as other logic inputs with low input capacitance. The device features a tri-state output and six independent power-saving operation modes. The 74AHCT240D-Q100J is available in a 28-pin DIP package.

Application Field

The 74AHCT240D-Q100J is designed for use in applications requiring fast settle times, low power consumption and precise timing. It is ideal for driving high-speed memories, such as RAM and ROM, SRAM and FIFO (First In First Out) memories. It can also be used for driving high-speed logic inputs with low capacitance, such as multiplexers and shift registers. The device can be used in industrial, networking, communications, and healthcare applications.

Working Principle

The 74AHCT240D-Q100J is a logic buffer device, which enables the user to control and isolate the power supply and signal lines of a variety of digital, analog, and mixed signal devices. The device features a tri-state output and six independent operating modes that reduce the power consumption of the device by up to 94%.

The device is configured to provide either one signal or two signal outputs. For example, in the one signal mode, it can be used to provide a signal output from an oscilloscope or logic analyzer. In this mode, the signal is input from the primary input pin and is output from the secondary pin. In the two signal mode, it can be used to provide two independent signal outputs, one from each of the primary and secondary pins.

The 74AHCT240D-Q100J features ESD (Electro Static Discharge) protection on both primary and secondary pins. When the device is operating in the two signal mode, the ESD protection is provided by a dual level protection mechanism. This two level protection prevents any single ESD event from damaging the device.

The device also features a power down mode, which puts the device in a low power state. This low power state reduces the current consumption of the device by up to 94%, thus saving power and reducing heat dissipation. The power down mode can be used in industrial and medical applications where low power consumption is essential.

The 74AHCT240D-Q100J is available in a 28-pin DIP package and provides pin compatible replacements for existing logic devices in the market. It is an ideal solution for applications requiring a high-speed logic device with low power consumption and precise timing.
