16-bit inverting buffer/line driver (3-State)
Product specification
MB2240
FEATURES
• 16-bit bus interface
• Multiple VCC and GND pins minimize
switching noise
• 3-State buffers
• Live insertion/extraction permitted
• Output capability: +64 mA/–32mA
• Latch-up protection exceeds 500mA
per Jedec JC40.2 Std 17
• ESD protection exceeds 2000 V per
MIL STD 883 Method 3015 and
200 V per Machine Model
• Power-up 3-State
DESCRIPTION
The MB2240 high-performance BiC-
MOS device combines low static and
dynamic power dissipation with high
speed and high output drive.
The MB2240 device is an inverting
16-bit buffer that is ideal for driving bus
lines. The device features four Output
Enables (1OE, 2OE, 3OE, 4OE), each
controlling four of the 3-State outputs.
