Philips Semiconductors Product specification 74ABT573A Octal D-type transparent latch (3-State) The 74ABT573A device is an octal transparent latch coupled to eight 3-State output buffers. The two sections of the device are controlled independently by Enable (E) and Output Enable (OE) control gates. The 74ABT573A is functionally identical to the 74ABT373 but has a flow-through pinout configuration to facilitate PC board layout and allow easy interface with microprocessors. FEATURES • 74ABT573A is flow-through pinout version of 74ABT373 • Inputs and outputs on opposite side of package allow easy interface to microprocessors • 3-State output buffers • Common output enable • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 The data on the D inputs are transferred to the latch outputs when the Latch Enable (E) input is High. The latch remains transparent to the data inputs while E is High, and stores the data that is present one setup time before the High-to-Low enable transition. and 200 V per Machine Model • Power-up 3-State • Power-up reset 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 latch operation. DESCRIPTION When OE is Low, the latched or transparent 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 74ABT573A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

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.
