74F827SCX Application Field and Working Principle

74F827SCX is a logic-based device from the 7400-series TTL logic family which was designed by Fairchild Semiconductor in the 1970s. It belongs to the category of Buffers, Drivers, Receivers, and Transceivers. The 74F827SCX is a highly integrated device comprising of a single chip containing 16 buffered non-inverting data outputs (D[7:0]), one enable input (E), and two enable outputs (ENL and ENH). The 74F827SCX is a buffer and driver device which is used to provide a higher current output while taking in a lower current input. Operated at single 5-volt supply voltage, this device provides an efficiently buffered data and clock output between the range of 4.2 volts to 5.5 volts. Also the device features low addition capacitance to reduce timing skews between the buffered data and clock signals. The 74F827SCX logic device is used in applications where a high-speed data transmission is necessary. A typical example of such an application is in a microprocessor system for buffering operations such as instruction, address and data read and write cycles. This device carries out its operation by taking in data and clock signals inputs in the74F827SCX. Then data is buffered by passing it through the internal 16 gate buffers with amplification and then finally the output is sent out from the 16 non-inverting data outputs with minimal processing delays and speed. The 74F827SCX logic device function as an efficient buffer driver. Buffer drivers are made up of two transistors which are used to amplify the input signal by an appropriate amount so that the output can drive a load properly. This device comprises of an NMOS P-channel device (in the form of a FET), working as the input buffer, and another NMOS N-channel device (in the form of a FET) which works as the output driver. The 74F827SCX has two types of drivers namely, high and low drivers. The high driver takes the highest output (7th bit) of the input and OFF loads it at the level of the output ENH pin, while the low driver takes the lowest output (0th bit) of the input and OFF loads it at the level of the output ENL pin. These two drivers help the device to drive the output with the correct voltage levels, hence the correct logic output from the device. Apart from the internal buffer, the 74F827SCX also comprises of two sets of transistors - one N-channel and one P-channel. The N-channel set is to draw a high output for ENH and the P-channel sets is to draw a low output for ENL. There are two control signals available in 74F827SCX. The first one is ‘Enable’ input pin, which is used to control the output voltage, while the second one is the ‘ENH’ and ‘ENL’ pin, which controls the buffer’s output. At any given time, the 74F827SCX device is capable of transmitting data either in the form of low logic level (L) or high logic level (H) signals. If a valid logic signal is received at the data input, then the 74F827SCX will transmit the signal at the corresponding data output with the same logic level. On the other hand, if there is no valid logic signal from the data input, then the 74F827SCX will produce a high impedance state for that signal in the corresponding data output. In addition, this device also provides an on-chip high/low enable setup for controlling the output voltage of the data buffers. When ENH (or ENL) is taken low (high), the output voltage will be high (low). The output voltage is determined by the logic level of the enable input (E). If the enable input is high, then the data outputs will be high, while if the enable input is low then the data outputs will be low. The 74F827SCX is a highly integrated device which can be used in a wide range of applications. The buffering capability of this device is an essential part of many communication applications, ranging from consumer electronics to industrial automation. Its flexibility and simplicity makes the 74F827SCX a highly sought after device in industrial and consumer electronics. To summarize, the 74F827SCX is a buffer and driver device from the 7400-series TTL logic family which is used in applications needing faster data transmission. It consists of 16 buffered non-inverting outputs, one enable input and two enable outputs. The device is able to draw a high or low output depending on the enable input (E) and the two enable outputs (ENL and ENH). This device is popular in industrial and consumer electronics applications where buffering and driving data signals is essential.
