FEATURES
* 74ABT574A is flow-through pinout version of 74ABT374 * Inputs and outputs on opposite side of package allow easy
interface to microprocessors
DESCRIPTION
The 74ABT574A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT574A is an 8-bit, edge triggered register coupled to eight 3-State output buffers. The two sections of the device are controlled independently by the clock (CP) and Output Enable (OE) control gates. 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. When OE is Low, the stored data appears at the outputs. When OE is High, the outputs are in the High-impedance "off" state, which means they will neither drive nor load the bus. 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 eight 3-State buffers independent of the clock operation.
* 3-State outputs for bus interfacing * Power-up 3-State * Power-up reset * Common output enable * 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
* Live insertion/extraction permitted.

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 150C. 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. 4. This parameter is valid for any VCC between 0V and 2.1V, with a transition time of up to 10 msec. From VCC = 2.1V to VCC = 5V "10% a transition time of up to 100 sec is permitted.
