Description

The 4ABT16245 is a 16-bit (dual-octal) noninverting 3-state transceiver designed for synchronous two-way communication between data buses. The control function implementation minimizes external timing requirements.

This 4ABT16245 device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows 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 (OE) input can be used to disable the device so that the buses are effectively isolated.

To ensure the high-impedance state of 4ABT16245 during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.The SN74ABT16245 is available in TI's shrink small-outline package (DL), which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.The SN54ABT16245 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ABT16245 is characterized for operation from 40°C to 85°C.
