SN54AS640 - OCTAL BUS TRANSCEIVERS

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 upon the level at the direction-control (DIR) input.

SN54ALS640B, SN54AS640, SN74ALS640B, SN74AS640 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SDAS122A – DECEMBER 1983 – REVISED JANUARY 1995 • Bidirectional Bus Transceivers in High-Density 20-Pin Packages • Inverting Logic • Package Options Include Plastic Small-Outline (DW) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 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 upon 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. SN54ALS640B, SN54AS640 . . .
