Octal buffer/line driver with 30Ω series
termination resistors (3-State)
Product specification
74ABT2244
FEATURES
• Octal bus interface
• 3-State buffers
• Live insertion/extraction permitted
• Outputs include series resistance of 30Ω, making external
termination resistors unnecessary
• Output capability: +5mA/–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
• Power-up 3-State
• Same part as 74ABT244-1
• Inputs are disabled during 3-State mode
DESCRIPTION
The 74ABT2244 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed.
The 74ABT2244 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 74ABT2244 is designed with 30Ω series resistance in both the
High and Low states of the output. This design reduces line noise in
applications such as memory address drivers, clock drivers and bus
receivers/transmitters.
The 74ABT2244 is the same as the 74ABT244-1. The part number
has been changed to reflect industry standards.
