FEATURES
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
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

DESCRIPTION
The 74ABT821 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT821 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 74ABT821 is a buffered 10-bit wide version of the
74ABT374/74ABT534 functions.
The 74ABT821 is a 10-bit, edge triggered register coupled to ten
3-State output buffers. The two sections of the device are controlled
independently by the clock (CP) and Output Enable (OE) control
gates.
The register is 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 3-State output buffers are designed to drive heavily loaded
3-State buses, MOS memories, or MOS microprocessors.
The active Low Output Enable (OE) controls all ten 3-State buffers
independent of the register operation. When OE is Low, the data in
the register appears at the outputs. When OE is High, the outputs
are in high impedance ”off” state, which means they will neither drive
nor load the bus.
