1997 Feb 26 853-1457 17800

FEA TURES

•Ideal for addressable register applications

•8-bit positive edge-triggered register

•Enable for address and data synchronization applications

•Output capability: +64mA/-32mA

•Latch-up protection exceeds 500mA per Jedec JC40.2 Std 17

•ESD protection exceeds 2000V per MIL STD 883 Method 3015

and 200V per Machine Model

•Power-up reset

DESCRIPTION

The 74ABT377A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

The 74ABT377A has 8 edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common buffered clock (CP) input loads all flip-flops simultaneously when the Enable (E

) input is

Low. 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 E

input must be stable one setup time prior to the Low-to-High

clock transition for predictable operation.

NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability .

2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.

3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:

1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.

2. This is the increase in supply current for each input at 3.4V.

3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
