Logic - Buffers, Drivers, Receivers, Transceivers74AHC244D,112 The 74AHC244D,112 is a part of the 74AHC244 family of logic chips. It is an octal non-inverting buffer/driver with 3-state outputs. It is designed to extend logic range and reduce loading with TTL and JEDEC approved signal levels, and is fully compatible with TTL levels operating at most of the common logic levels. The 74AHC244D,112 is primarily used in driving data and address buses, and can also be used as output ports or signal lines. It is also suitable for multiplexers/demultiplexers and other applications requiring higher speed and wider range of power level shifting.Application FieldThe 74AHC244D,112 is suitable for a variety of applications, such as multiplexers/demultiplexers, data and address buses, output ports and signal lines. It is specifically designed to extend logic range, reduce loading on TTL and JEDEC approved signals, and is compatible with most of the common logic levels.The chip can also be used in applications that require multiplexers/demultiplexers and other applications that require higher speed and wider range power level shifting. The device has the capability to drive up to twenty-four (24) buffers for very low voltage logic devices. It can also be used for RISC microcontroller projects, EEPROM read/write operations, logic level conversion, and for other applications that require data transfer between logic levels.Working PrincipleThe basic operation of the 74AHC244D,112 is relatively simple. It consists of two main parts - the octal transceiver and the three-state outputs. The octal transceiver is used to establish the connection between the data lines (inputs) and the output lines (outputs). The octal driver allows the reception and transmission of logic signals, and through the help of the three-state outputs, data can be outputted or received depending on the particular application.When the “output enable” input (OE) is high, the output lines are disabled and the input lines become active. During this time, data enters the chip via the inputs, is processed through the octal transceiver, and is outputted as logic signals. When the OE input is low, data can no longer enter the chip and the outputs are enabled. Data stored in the octal drives is then transmitted onto the output lines. The 74AHC244D,112 is also equipped with an open drain (OD) output, which can be used to provide more flexibility in applications. The OD output behaves like an inverting buffer and can be used to create a low active device out of a high active device, for example.In summary, the 74AHC244D,112 is a multifunctional chip that is suitable for a variety of applications. It is designed to extend logic range and reduce loading with TTL and JEDEC approved levels and is compatible with most of the common logic levels. The octal transceiver combined with the three-state outputs allows data input, processing and outputting of logic signals in high speed and wide range power level shifting. The OD output also provides more flexibility in applications by allowing the creation of low active devices out of high active devices.
