Dual 9-bit D-type flip-flop with
reset and enable (3-State)
Product specification
MB2823
FEATURES
• 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 insertation/extraction permitted
• Power-up 3-State
• Power-up Reset
• Output capability: +64mA/–32mA
• Latch-up protection exceeds 500mA per
Jedec JC40.2 Std 17
• ESD protection exceeds 2000 V per MIL
STD 883 Method 3015 and 200 V per
Machine Model
DESCRIPTION
The MB2823 dual 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 MB2823 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.
