Octal buffer/line driver (3-State)
Product specification
74ABT541
FEATURES
• Octal bus interface
• Functions similar to the ’ABT241
• Provides ideal interface and increases fan-out of MOS
Microprocessors
• 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
• 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.
