series termination resistors (3-State)
Product specification
74LVT2244
FEATURES
• Octal bus interface
• 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 LVT2244 is a high-performance BiCMOS product designed for
VCC operation at 3.3V.
This device is an octal buffer that is ideal for driving bus lines. The
device features two Output Enables (OE1, OE2), each controlling
four of the 3-State outputs.
The 74LVT2244 is designed with 30Ω 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.
