Octal buffer/line driver (3-State)
74ABT541
FEATURES
* Octal bus interface * Functions similar to the 'ABT241 * Provides ideal interface and increases fan-out of MOS
Microprocessors
* ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
* Live insertion/extraction permitted
DESCRIPTION
The 74ABT541 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT541 device is an octal buffer that is ideal for driving bus lines. The outputs are all capable of sinking 64mA and sourcing 32mA. The device features input and outputs on opposite sides of the package to facilitate printed circuit board layout.
* Efficient pinout to facilitate PC board layout * 3-State buffer outputs sink 64mA and source 32mA * Power-up 3-State * Latch-up protection exceeds 500mA per Jedec JC40.2 Std 17

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.
