3.3V ABT 16-Bit Transceiver/Register
with TRI-STATE

Outputs
General Description
The LVT16652 consists of sixteen bus transceiver circuits
with D-type flip-flops, and control circuitry arranged for multi-
plexed 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 opera-
tion. Data on the A or B bus will be clocked into the registers
as the appropriate clock pin goes to HIGH logic level. Out-
put Enable pins (OEAB, OEBA) are provided to control the
transceiver function.
The transceivers are designed for low-voltage (3.3V) V
CC
applications, but with the capability to provide a TTL inter-
face 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.
