3.3V Octal buffer/line driver (3-State)
2
1998 Feb 19
853-1839 18991
FEATURES
Octal bus interface
3-State buffers
Output capability: +64mA/-32mA
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.
DESCRIPTION
The 74LVT241 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74LVT241 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.
