DM74ALS652WMX Datasheet/PDFThe DM74ALS652WMX is a high-speed octal line receiver that has been designed for use in bus-oriented systems. It has been fabricated using the latest high-speed CMOS technology and is capable of operating at speeds of up to 1.6 Gbps. The DM74ALS652WMX offers excellent power-consumption performance and comes in a variety of packages that can be used for LVPECL, LVDS, and CML signaling. This device can be used in applications where data transmission at high speeds and low power consumption are necessary.
The DM74ALS652WMX is a two-channel octal line receiver that operates in both low-voltage (1.8V) and high-voltage (3.3V) environments. It extends data bus widths up to 8 bits and increases communications speed up to 1.6 Gbps. Its low-voltage operation facilitates integration of the device into most high-speed, low-power circuits. The actual data transfer rate is dependent on the capacitance of the system, but the device is designed to withstand up to 20 pF of capacitance in 3.3V and up to 50 pF in 1.8V cases. This device also features Active Bus Termination, allowing it to drive buses up to 50 ohms without external resistors.
The DM74ALS652WMX utilizes a D-type flip-flop architecture that is independent, bus-oriented, and daisy-chainable. Each of the eight channels contains a data input (D) and an inverted data output (Q) terminal, as well as an active-low asynchronous reset input (R). When R is low, all Q outputs will be driven to a low state. In addition, the device contains three-state outputs, an active-high enable (E), and a Clock input (C). These further increase the number of possible uses and applications.
The working principle of the DM74ALS652WMX is based on the principle of a D-type flip-flop. In a D-type flip-flop, the data input (D) is given at the same time that the Clock input (C) goes high. When C is high, the value at the D input is copied directly to the inverted data output (Q), allowing for data transfer. The three-state outputs can then be activated via the active-high Enable terminal (E).
The DM74ALS652WMX is an ideal choice for applications that require high-speed data transmission at low power consumption, such as in communication systems, routers, switches, and high-performance computers. Its two-channel, octal line receiver can extend data bus widths up to 8 bits and increases data transmission speed up to 1.6 Gbps, eliminating the need for many external bus pieces. Its low-voltage operation and active bus termination also aid in reducing power consumption, making it an efficient and reliable choice.
