74VHC240SJ is a 16-bit buffer, driver, receiver, and transceiver chip designed for applications requiring high speed and low power. The chip family integrates logic, transceiver, receiver and driver functions into one device. It is often used in high speed digital systems such as telecom, military, and aerospace applications.
Application Field
This device is capable of driving up to 24mA at 3.3V and 20mA at 5V with a low-power consumption of only 2.5mA per channel. It is used in many applications including video data transmission, switches and routers, digital control of high speed processes, radar systems, satellite communication, backplanes and Gb Ethernet. It is also used in multi-site remote control, industrial process control, telecommunications, and data storage.
Working Principle
The 74VHC240SJ consists of sixteen non-inverting buffers with latch enable inputs. Each double buffer consists of two sections, the input side and the output side. Data is clocked from the input section to the output section via the latch enable input. The logic inputs of each buffer meet the requirements of both TTL and CMOS logicfor all inputs and outputs. The outputs are open-drain which represent a logical zero in the steady state. When a logical one is required, the output must be enabled by an external pull up resistor connected to VCC, the supply voltage.
The 74VHC240SJ has two power supply pins, VCC and VEE. VCC should always be connected to the logic power supply voltage, while VEE should be connected to the logic ground. This supply allows the output transistor to turn of f quickly, which increases the switching speeds of the device.
Conclusion
The 74VHC240SJ is a versatile and efficient buffer, driver, receiver, and transceiver. It is used widely in digital systems and other applications requiring high speed and low power. Its outputs are open-drain which allows for quick switching speeds, and it has two power supply pins for increased compatibility with both TTL and CMOS logic.
