1 / 5 page SN74ALS1640A, SN74ALS1645A OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SDAS246B – DECEMBER 1982 – REVISED FEBRUARY 1997 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Bidirectional Bus Transceivers in High-Density 20-Pin Packages D Lower-Power Versions of SN74ALS640B and SN74ALS645A D Package Options Include Plastic Small-Outline (DW) Packages and Standard Plastic (N) 300-mil DIPs description These octal bus transceivers are designed for asynchronous two-way communication between data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending on the level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. The SN74ALS1640A features inverting logic, while the SN74ALS1645A features noninverting logic. The SN74ALS1640A and SN74ALS1645A are characterized for operation from 0 °C to 70°C.
