1998 Feb 13 853-1976 18960
FEATURES
• 16-bit bus interface
• 5V I/O compatibile
• 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
• Live insertion/extraction permitted
• Outputs include series resistance of 30Ω making external
termination resistors unnecessary
• Power-up 3-State
• No bus current loading when output is tied to 5V bus
• ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
DESCRIPTION
The 74ALVT162240 is a high-performance BiCMOS product
designed for V
CC
operation at 2.5V or 3.3V with I/O compatibility up
to 5V.
This device is an inverting 16-bit buffer that is ideal for driving bus
lines. The device features four Output Enables (1OE
, 2OE, 3OE,
4OE
), each controlling four of the 3-State outputs.
The 74ALVT162240 is designed with 30Ω series resistance in both
the pull-up and pull-down output structures. This design reduces line
noise in applications such as memory address drivers, clock drivers,
and bus receivers/transmitters.
