Description

The 74LVT16646 contains sixteen noninverting bidirectional registered bus transceivers providing multiplexed transmission of data directly from the input bus or from the internal storage registers. Each byte has separate control inputs which can be shorted together for full 16-bit operation. The DIR inputs determine the direction of data flow through the device. The CPAB and CPBA inputs load data into the registers on the LOW-to-HIGH transition (see Functional Description).

The 74LVT16646 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

These transceivers of the 74LVT16646 are designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment. The LVT16646 and LVTH16646 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
