1
1996 May 29 853-1840 16867
FEATURES
3-State buffers
Output capability: +12mA/-12mA
TTL input and output switching levels
Input and output interface capability to systems at 5V supply
Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
Power-up 3-State
Live insertion/extraction permitted
No bus current loading when output is tied to 5V bus
Latch-up protection exceeds 500mA per JEDEC Std 17
ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model.
Outputs include series resistance of 30Ω, making external
termination resistors unnecessary.
DESCRIPTION
The 74LVT2241 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.
The 74LVT2241 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 74LVT2241 is designed with 30 series resistance in both the
High and Low states of the output. This design reduces the line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters.

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 negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
