853-2114 19927
FEATURES
Two sets of high speed parallel registers with positive
edge-triggered D-type flip-flops
5V I/O Compatible
Ideal where high speed, light loading, or increased fan-in are
required with MOS microprocessors
Live insertion/extraction permitted
Power-up 3-State
Power-up Reset
Output capability: +12mA/–12mA
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
Bus hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
Outputs include series resistance of 30
making external
termination resistors unnecessary
DESCRIPTION
The 74ALVT162823 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 74ALVT162823 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.
The 74ALVT162823 is designed with 30
series resistance in both
the pull-up and pull-down output structures. This design reduces line
noise in applications such as memory address drivers, clock drivers,
and bus receivers/transmitters.
