(3-State)
Product specification
74ABT2241
FEATURES
• Octal bus interface
• 3-State buffers
• Power-up 3-State
• Output capability: +12mA/–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
DESCRIPTION
The 74ABT2241 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT2241 device is an octal buffer that is ideal for driving bus
lines. The device features two Output Enables (1OE, 2OE), each
controlling four of the 3-State outputs.
The 74ABT2241 is designed with 30W series resistance in both the
High and Low states of the output. The design reduces line noise in
applications such as memory address drivers, clock drivers, and bus
receivers/transceivers.
