Description

The 74ACT16474 are noninverting 18-bit registered bus transceivers composed of two 9-bit sections with separate control signals. For either 9-bit transceiver section, data flow in the A-to-B mode is controlled by output-enable (1OEAB or 2OEAB) and clock (1CLKAB or 2CLKAB) inputs. When 1OEAB or 2OEAB is low, the corresponding outputs are active (high or low) and take on either the current data on low-to-high transition of 1CLKAB or 2CLKAB or the previously stored data if 1CLKAB or 2CLKAB is low.

When 1OEAB or 2OEAB is high, the corresponding outputs are in the high-impedance state. 1OEAB or 2OEAB does not affect the operation on the internal registers. Previously stored data can be retained or new data can be entered while the outputs are in the high-impedance state.

Data flow from B to A is similar, but uses 1OEBA and/or 2OEBA and 1CLKBA and/or 2CLKBA.

The 74ACT16474 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 74ACT16474 is characterized for operation over the full military temperature range of 55°C to 125°C. The 74ACT16474 is characterized for operation from 40°C to 85°C.
