description
These 18-bit universal bus transceivers combine D-type latches and D-type flip-flops to allow data flow in transparent, latched, clocked, and clock-enabled modes.
Data flow in each direction is controlled by output-enable (OEAB and OEBA), latch-enable (LEAB and LEBA), and clock (CLKAB
and CLKBA) inputs. The clock can be controlled by the clock-enable (CLKENAB and CLKENBA) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is high. When LEAB is low, the A data is latched if CLKAB
is held at a high or low logic level. If LEAB is low, the A-bus data is stored in the latch/flip-flop on the high-to-low transition of CLKAB. Output enable OEAB
is active low. When OEAB is low, the outputs are active. When OEAB is high, the outputs are in the high-impedance state.

description (continued)
Data flow for B to A is similar to that of A to B, but uses OEBA, LEBA, CLKBA, and CLKENBA. T o ensure the high-impedance state 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 SN54ABT16600 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT16600 is characterized for operation from –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51.

All typical values are at VCC = 5 V.
Not more than one output should be tested at a time, and the duration of the test should not exceed one second.

The parameters I

include the input leakage current.
This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
