MB224416-bit buffer/line driver (3-State)
2
1998 Jan 16 853–1572 18869
FEATURES
• 16-bit bus interface
• Multiple V
CC
and GND pins minimize switching noise
• Power-up 3-State
• 3-State buffers
• Output capability: +64 mA/–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
DESCRIPTION
The MB2244 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The MB2244 device is an 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.
