SN74ALS638A
- Bidirectional Bus Transceivers in High-Density 20-Pin Packages
- Choice of True or Inverting Logic
- A-Bus Outputs Are Open Collector; B-Bus Outputs Are 3 State
- Package Options Include Plastic Small-Outline (DW) Packages and Standard Plastic (N) 300-mil DIPs
These octal bus transceivers are designed for asynchronous two-way
communication between open-collector and 3-state buses. The devices
transmit data from the A bus (open-collector) to the B bus (3 state)
or from the B bus to the A bus, depending on the logic level at the
direction-control (DIR) input. The output-enable (
) input can be used to disable the
device so the buses are isolated.
The -1 version of SN74ALS638A is identical to the standard version, except that the recommended maximum IOL is increased to 48 mA.
The SN74ALS638A, SN74ALS639A, SN74AS638A, and SN74AS639 are characterized for operation from 0°C to 70°C.
