termination resistors unnecessary
Live insertion/extraction permitted
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
DESCRIPTION
The 74ALVT162241 is a high-performance BiCMOS product designed
for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V.
This device is a 16-bit buffer that is ideal for driving bus lines. The
device features four Output Enables (1OE, 2OE, 3OE, 4OE), each
controlling four of the 3-State outputs.
The 74ALVT162241 is designed with 30
W series resistance in both
High and Low output stages. This design reduces the line noise in
applications such as memory address drivers, clock drivers and bus
receivers/transmitters. The series termination resistors reduce
overshoot and undershoot and are ideal for driving memory arrays.
