Outputs include series resistance of 30 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
DESCRIPTION
The 74ALVT162245 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 transceiver featuring non-inverting 3-State
bus compatible outputs in both send and receive directions. The
control function implementation minimizes external timing
requirements. The device features an Output Enable (nOE) input for
easy cascading and a Direction (DIR) input for direction control.
The 74ALVT162245 is designed with 30
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 transceivers/transmitters.
