General description
The 74ABT162245A is a high-performance BiCMOS product, which combines low static
and dynamic power dissipation with high speed.
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 two output enable inputs (nOE) for
easy cascading and two direction inputs (nDIR) for direction control.
The 74ABT162245A is designed with 30 Ω series resistance in both the upper and lower
output structures. This design reduces line noise in applications such as memory address
drivers, clock drivers and bus receivers and transmitters.
Two options are available, 74ABT162245A which does not have the bus hold feature and
the 74ABTH162245A which incorporates the bus hold feature.

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which
are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
