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 to 125C. The 74AC16245 is characterized for operation from to 85C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The maximum package power dissipation is calculated using a junction temperature of 150_C and a board trace length of 750 mils.
