3.3V 16-bit inverting buffer/driver with 30Ω
termination resistors (3-State)
FEA TURES
•16-bit 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
•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
•Latch-up protection exceeds 500mA per JEDEC Std 17
•ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
•Same part as 74LVT16240A-1

DESCRIPTION
The 74LVT162240A is a high-performance BiCMOS product
designed for V
This device is an inverting 16-bit buffer that is ideal for driving bus
lines. The device features four Output Enables (1OE
4OE
), each controlling four of the 3-State outputs.
The 74LVT162240A 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.
The 74LVT162240A is the same as the 74LVT16240A-1. The part
number has been changed to reflect industry standards.
