Philips Semiconductors Product specification
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.
