16-bit bus transceiver with 30 Ω series termination resistors; 3-state

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.
