description

The 'AHC16245 are 16-bit (dual-octal) noninverting 3-state transceivers designed for synchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.

These devices can be used as two 8-bit transceivers or one 16-bit transceiver. They allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable () input can be used to disable the device so that the buses are effectively isolated.

The SN54AHC16245 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74AHC16245 is characterized for operation from -40°C to 85°C.
