SN54ALS640B
- 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
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 can be
used to disable the device so that the buses are effectively
isolated.
The -1 version of the SN74ALS640B is identical to the standard version, except that the recommended maximum IOL for the -1 version is increased to 48 mA. There is no -1 version of the SN54ALS640B.
The SN54ALS640B and SN54AS640 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS640B and SN74AS640 are characterized for operation from 0°C to 70°C.
