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

These 18-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 'ABTH16823 CAN be used as two 9-bit Flip-Flops or one 18-bit Flip-Flop With the clock-enable (CLKEN) input low, the D-type Flip-Flops enter data on the low-to-high transitions of the Clock Taking CLKEN high disables the Clock Buffer latching the outputs. Taking the clear (CLR) input low causes the Q outputs to go low independently of the Clock
A buffered output-enable (OE) input CAN be used to place the nine outputs in either a normal Logic state (high or low Logic levels) 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.
OE 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.
When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, 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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid Logic level.
The SN54ABTH16823 is characterized for operation over the full military temperature range of -55C to 125C. The SN74ABTH16823 is characterized for operation from -40C to 85C.
