FEATURES
DESCRIPTION
• Two 8-bit bus interfaces
• Power-up 3-State
• Multiple VCC and GND pins minimize switching noise
• Provides ideal interface and increases fan-out of MOS
The MB2541 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
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.
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.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
