description

The ’ACT1284 are designed for asynchronous

two-way communication between data buses.

The control function minimizes external timing

requirements.

GND

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.

9 10 11 12 13

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.

The SN54ACT1284 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ACT1284 is characterized for operation from 0°C to 70°C.
