Product specification
74LVT162244B
3.3V 16-bit buffer/driver with 30
termination resistors (3-State)
2
1998 Oct 07
853-1779 20144
FEATURES
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
DESCRIPTION
The 74LVT162244B is a high-performance BiCMOS product
designed for VCC operation at 3.3V.
The 74LVT162244B is designed with 30
Ω 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.
