30Ω termination resistors (3-State)

Product specification

74ALVT162240

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 VCC 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.
