and 200V per Machine Model

DESCRIPTION

The 74LVT16646A is a high-performance BiCMOS product

designed for VCC operation at 3.3V.

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 (OE) input for

easy cascading and a Direction (DIR) input for direction control.

Data on the A or B bus is clocked into the registers on the Low to

High transition of the appropriate clock (CPAB or CPBA). The

select-control (SAB and SBA) inputs can multiplex stored and

real-time (transparent mode data).
