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.

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 ªrecommended operating conditionsº 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.
