FEATURES
74ABT2244
DESCRIPTION
• Octal bus interface
• 3-State buffers
• Live insertion/extraction permitted
• Outputs include series resistance of 30Ω, making external
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.
termination resistors unnecessary
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.
• Output capability: +5mA/–32mA
• Latch-up protection exceeds 500mA per Jedec Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
The 74ABT2244 is the same as the 74ABT244-1. The part number
has been changed to reflect industry standards.
and 200 V per Machine Model
• Power-up 3-State
• Same part as 74ABT244-1
• Inputs are disabled during 3-State mode

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

NOTES:
1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4V.
3. This parameter is valid for any VCC between 0V and 2.1V, with a transition time of up to 10msec. From VCC = 2.1V to VCC = 5V ± 10% a
transition time of up to 100µsec is permitted.
