description

The ’AC16245 are 16-bit bus transceivers

organized as dual-octal noninverting 3-state

transceivers designed for asynchronous two-way

communication between data buses. The control

function implementation minimizes external timing

requirements

These devices allow data transmission from the A

bus to the B bus or from the B bus to the A bus,

depending upon the logic level at the direction

control (DIR) input. The output-enable input (OE)

can be used to disable the devices so that the

buses are effectively isolated.

The 74AC16245 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and

functionality of standard small-outline packages in the same printed-circuit-board area.

The 54AC16245 is characterized for operation over the full military temperature range of –55°C to 125°C. The

74AC16245 is characterized for operation from –40°C to 85°C.
