3.3V 16-bit 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
terminating 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 74LVT16244B-1
74L VT162244B
DESCRIPTION
The 74LVT162244B is a high-performance BiCMOS product
designed for V
The 74LVT162244B is designed with 30Ω series resistance in both
the High and Low states of the output. This design reduces line
noise in applications such as memory address drivers, clock drivers,
and bus receivers/transmitters.
This device is a 16-bit buffer and line driver featuring non-inverting
3-State bus outputs. The device can be used as four 4-bit buffers,
two 8-bit buffers, or one 16-bit buffer.
The 74LVT162244B is the same as the 74LVT16244B-1. The part
number has been changed to reflect industry standards.
