说明

This 25-octal bus transceiver is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction-control (DIR) input. The output-enable () input can be used to disable the device so the buses are effectively isolated.

The SN74BCT25642 is capable of sinking 188-mA I_OL (A port), which facilitates switching 25- transmission lines on the incident wave. It is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented transceivers. The distributed V_CC and GND pins minimize the noise generated by the simultaneous switching of the outputs.

特性

• State-of-the-Art BiCMOS Design Significantly Reduces I_CCZ
• ESD Protection Exceeds 2000 V Per MIL-STD-883C, Method 3015; Exceeds 200 V Using Machine Model (C = 200 pF, R = 0)
• Designed to Facilitate Incident-Wave Switching for Line Impedances of 25-or Greater
• Distributed V_CC and GND Pins Minimize Noise Generated by the Simultaneous Switching of Outputs
• The A Port Features Open-Collector Outputs That Provide 188-mA I_OL to Allow for Heavy DC Loading on Open-Collector Outputs
• Eliminates Need for 3-State Overlap Protection on A Ports
• Package Options Include Plastic Small-Outline (DW) Packages and Standard Plastic 300-mil DIPs (NT)
