16-bit Bus Transceiver/register 3-state - Nxp Semiconductors

The 74ABT16646 highperformance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT16646 16-bit transceiver Register consists of two sets of Bus Transceiver circuits with 3-State outputs, D-type Flip-Flops and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal Registers Data on the A or B bus will be clocked into the Registers as the appropriate Clock pin goes High. Output Enable (nOE) and Direction (nDIR) pins are provided to control the transceiver function. In the transceiver mode, data present at the high impedance port may be stored in either the A or B Register or both. The select (nSAB, nSBA) pins determine whether data is stored or transferred through the device in real-time. The nDIR determines which bus will receive data when the nOE is active Low. In the isolation mode (nOE = High), data from Bus A may be stored in the B Register and/or data from Bus B may be stored in the A Register When an output function is disabled, the input function is still enabled and may be used to store and transmit data. Only one of the two buses, A or B may be driven at a time. Two options are available, 74ABT16646 which does not have the bus-hold feature and 74ABTH16646 which incorporates the bus-hold feature.
