Descriptions
Descriptions of Texas Instruments SN74ALS641A-1N provided by its distributors.
Bus XCVR Single 8-CH Open Collector 20-Pin PDIP Tube
LOGIC, BUS TRANSCVR OCTAL, 20DIP; Logic Device Type:Transceiver, Non Inverting; Supply Voltage Range:4.5V to 5.5V; Logic Case Style:DIP; No. of Pins:20; Operating Temperature Range:0°C to +70°C; SVHC:No SVHC (20-Jun-2011); Logic Function Number:74641; Logic IC Base Number:74641; Logic IC Family:ALS; Logic IC Function:Octal Bus Transceiver with Open-Collector Outputs; Package / Case:PDIP; Supply Voltage Max:5.5V; Supply Voltage Min:4.5V; Termination Type:Through Hole
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 input 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 IOL is increased to 48 mA in the -1 versions. The SN74ALS641A, SN74ALS642A, and SN74AS641 are characterized for operation from 0°C to 70°C.
