description/ordering information

The ’ACT1284 devices are designed for
asynchronous two-way communication between
data buses. The control function minimizes
external timing requirements.
The devices allow data transmission in either the
A-to-B or the B-to-A direction for bits 1, 2, 3, and
4, depending on the logic level at the
direction-control (DIR) input. Bits 5, 6, and 7,
however, always transmit in the A-to-B direction.
The output drive for each mode is determined by the high-drive (HD) control pin. When HD is high, the high drive
is delivered by the totem-pole configuration, and when HD is low, the outputs are open drain. This meets the
drive requirements as specified in the IEEE 1284-I (level-1 type) and the IEEE 1284-II (level-2 type) parallel
peripheral-interface specification.
