74ABT16823A

•Two sets of high speed parallel registers with positive edge-triggered D-type flip-flops
•Ideal where high speed, light loading, or increased fan-in are required with MOS microprocessors
•Live insertion/extraction permitted
•Power-up 3-State
•74ABTH16823A incorporates bus-hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs
•Power-up Reset
•Output capability: +64mA/32mA
•Latch-up protection exceeds 500mA per Jedec Std 17
•ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model

The 74ABT16823A 18-bit bus interface register is designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider data/address paths of buses carrying parity.

The 74ABT16823A has two 9-bit wide buffered registers with Clock Enable (nCE ) and Master Reset (nMR) which are ideal for parity bus interfacing in high microprogrammed systems.

The registers are fully edge-triggered. The state of each D input, one set-up time before the Low-to-High clock transition is transferred to the corresponding flip-flop's Q output.

Two options are available, 74ABT16823A which does not have the bus-hold feature and 74ABTH16823A which incorporates the bus-hold feature.
