74ACT11240DBRE4

The 74ACT11240DBRE4 is a high speed CMOS octal buffer/line driver, manufactured by Texas Instruments, Inc. It is composed of an octal bus transceiver that features separate data and direction logic inputs and data output enable controls.

The 74ACT11240DBRE4 is a 3-state octal buffer/line driver with inverted outputs. It is designed to provide high speed operation in bus-oriented applications. This integrated circuit has 8 independent outputs. Each output is capable of driving 10 LSTTL loads or 2 high-speed TTL loads.

Its application field involves multidrop bus-oriented applications such as address and data buses in computers and peripherals, telephone line interface circuits, and clock drivers for large fan-in peripherals. It is designed to interface 5V microprocessors to memory and I/O circuits using a common for high speed data transmission.

The 74ACT11240DBRE4 has an open drain-enabled feature that allows to put an out of the buffer on an associated output pin. This is done without disabling the other outputs. The device also features an input protection circuit that protects the inputs against damage caused by high static voltages or ESD.

The 74ACT11240DBRE4 has three working modes, which are the Non-Inverting mode, the Inverting mode, and the High Impedance mode. In the Non-Inverting mode, it acts as a non-inverting buffer, with the outputs the same polarity as the inputs. In the Inverting mode, it works as an inverting buffer, with the outputs the opposite polarity of the inputs. Finally, in the High Impedance mode, all outputs are disabled.

In conclusion, the 74ACT11240DBRE4 is a high speed CMOS octal buffer/line driver, designed to provide high speed operation in bus-oriented applications. It has a open drain-enabled feature that allows putting an out of the buffer on an associated output pin, and it also has an input protection circuit. It has three working modes, the Non-Inverting mode, the Inverting mode, and the High Impedance mode.
