16-bit bus transceivers and registers with 3-state outputs
The SN54ABT16646 and SN74ABT16646 devices consist of bus-transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from internal registers. These devices can be used as two 8-bit transceivers or one 16-bit transceiver, allowing data to be clocked into registers on the low-to-high transition of the appropriate clock input.
| High-level output current | -24 mA to -32 mA |
|---|---|
| Operating temperature (Military) | -55°C to 125°C |
