产品概述
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.
