74ABT821
10-bit D-type flip-flop; positive-edge trigger; 3-state
Rev. 03 — 25 February 2010
Product data sheet
1. General 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 74ABT374A.
The 74ABT821 is a 10-bit, edge-triggered register coupled to ten 3-state output buffers.
The device is controlled 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 output Q of the flip-flop.
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.
2. Features and benefits

For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
[2]
This parameter is valid for any VCC between 0 V and 2.1 V with a transition time of up to 10 ms. For VCC = 2.1 V to VCC = 5 V ± 10 %, a
transition time of up to 100 µs is permitted.
[3]
Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
[4]
This is the increase in supply current for each input at 3.4 V.
