FEATURES
DESCRIPTION
The MB2541 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
• Two 8-bit bus interfaces
• Power-up 3-State
• Multiple V and GND pins minimize switching noise
The MB2541 has two 8-bit buffers that are ideal for driving bus lines.
The outputs are all capable of sinking 64mA and sourcing 32mA.
CC
• Provides ideal interface and increases fan-out of MOS
Microprocessors
• 3-State buffers sink 64mA and source 32mA
• 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
• Inputs are disabled during 3-State mode

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.
