20-Bit Bus Interface Flip-Flops With 3-State Outputs

These 20-bit Flip-Flops feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing wider Buffer Registers I/O ports, bidirectional bus drivers with parity, and working Registers
The 'ABT16821 CAN be used as two 10-bit Flip-Flops or one 20-bit Flip-Flop The 20 Flip-Flops are edge-triggered D-type Flip-Flops On the positive transition of the Clock (CLK) input, the device provides true data at the Q outputs.
A buffered output-enable () input CAN be used to place the ten outputs in either a normal Logic state (high or low Logic level) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without need for Interface or pullup components.
does not affect the internal operation of the Flip-Flops Old data CAN be retained or new data CAN be entered while the outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power down, 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 SN54ABT16821 is characterized for operation over the full military temperature range of -55?C to 125?C. The SN74ABT16821 is characterized for operation from -40?C to 85?C.
