SN64BCT25245 Datasheet | Texas Instruments

description The SN64BCT25245 is a 25-Ω octal bus transceiver designed for asynchronous munication between data buses. It improves both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented transceivers. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the direction-control (DIR) input. The output-enable (OE) input can disable the device so that both buses are effectively isolated. This transceiver is capable of sinking 188-m A IOL, which facilitates switching 25-Ω transmission lines on the incident wave. The distributed VCC and GND pins minimize switching noise for more reliable system operation. The outputs are in a high-impedance state during power up and power down while the supply voltage is less than approximately 3 V. The SN64BCT25245 is characterized for operation from - 40°C to 85°C and 0°C to 70°C.
