General Description

The LVT16652 consists of sixteen bus transceiver circuits

with D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or

from the internal registers. Each byte has separate control

inputs which can be shorted together for full 16-bit operation. Data on the A or B bus will be clocked into the registers

as the appropriate clock pin goes to HIGH logic level. Output Enable pins (OEAB, OEBA) are provided to control the

transceiver function.

The transceivers are designed for low-voltage (3.3V) VCC

applications, but with the capability to provide a TTL interface to a 5V environment. The LVT16652 is fabricated with

an advanced BiCMOS technology to achieve high speed

operation similar to 5V ABT while maintaining a low power

dissipation.
