UNIT

2.5V/3.3V 16-bit inverting buffer/driver with 30Ω termination resistors (3-State)

FEA TURES

•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 to 5V .

This device is an inverting 16-bit buffer that is ideal for driving bus lines. The device features four Output Enables (1OE 4OE

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.
