74ACT1662316-Bit Bus Transceivers With 3-State Outputs | Logic | 2 | Obsolete | The 'ACT16623 are 16-bit transceivers designed for asynchronous two-way communication between data buses. The control-function implementation allows for maximum flexibility in timing.
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 output-enable (and OEAB) inputs. The output-enable inputs can be used to disable the device so that the buses are effectively isolated.
The dual-enable configuration gives the bus transceiver the capability to store data by simultaneously enablingand OEAB. Each output reinforces its input in this transceiver configuration. When both control inputs are enabled and all other data sources to the two sets of bus lines are at high impedance, the bus lines remain at their last states.
The 74ACT16623 is packaged in TI's shrink small-outline package, which provides twice the functionality of standard small-outline packages in the same printed-circuit-board area.
The 54ACT16623 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT16623 is characterized for operation from -40°C to 85°C.

74ACT1665216-Bit Transceivers And Registers With 3-State Outputs | Logic | 1 | Obsolete | The 'ACT16652 are 16-bit bus transceivers consisting of D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. The devices can be used as two 8-bit transceivers or one 16-bit transceiver.
Complementary output-enable (OEAB and) inputs are provided to control the transceiver functions. Select-control (SAB and SBA) inputs are provided to select whether real-time or stored data is transferred. A low input level selects real-time data, and a high input level selects stored data. The circuitry used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data. Figure 1 illustrates the four fundamental bus-management functions that can be performed with the 'ACT16652.
Data on the A or B bus, or both, can be stored in the internal D flip-flops by low-to-high transitions at the appropriate clock (CLKAB or CLKBA) inputs, regardless of the levels on the select-control or output-enable inputs. When SAB and SBA are in the real-time transfer mode, it is also possible to store data without using the internal D-type flip-flops by simultaneously enabling OEAB and. In this configuration, each output reinforces its input. Thus, when all other data sources to the two sets of bus lines are at high impedance, each set of bus lines remains at its last state.

The 'ACT16825 can be used as two 9-bit buffers or one 18-bit buffer. They provide true data from A to Y.
The 3-state control gate is a 2-input NOR gate; therefore, if either output-enable (or) input is high, all nine affected outputs are in the high-impedance state.
