Description
General part information
SN74ALS642A-1 Series
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-enableinput disables the device so that the buses are effectively isolated.
The -1 versions of the SN74ALS641A and SN74ALS642A are identical to the standard versions, except that the recommended maximum IOLis increased to 48 mA in the -1 versions.
