74L VT2413.3V Octal buffer/line driver (3-State)
FEA TURES
•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
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
controlling four of the 3-State outputs.
, 2OE), each
•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.
