74LVTH16652
Low Voltage 16-Bit Transceiver/Register
with 3-STATE Outputs
General Description
The LVTH16652 consists of sixteen bus transceiver circuits
with D-type flip-flops, and control circuitry arranged for mul-
tiplexed 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 regis-
ters as the appropriate clock pin goes to the HIGH logic
level. Output Enable pins (OEAB, OEBA) are provided to
control the transceiver function (see Functional Descrip-
tion).
The LVTH16652 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
The transceivers are designed for low-voltage (3.3V) VCC
applications, but with the capability to provide a TTL inter-
face to a 5V environment. The LVTH16652 is fabricated
with an advanced BiCMOS technology to achieve high
speed operation similar to 5V ABT while maintaining low
power dissipation.
Features
s Input and output interface capability to systems at
5V VCC
s Bushold data inputs eliminate the need for external
pull-up resistors to hold unused inputs
s Live insertion/extraction permitted
s Power Up/Down high impedance provides glitch-free
bus loading
s Outputs source/sink 32 mA/+64 mA
s Functionally compatible with the 74 series 16652
s Latch-up performance exceeds 500 mA

Note 1: The data output functions may be enabled or disabled by various signals at OEAB or OEBA inputs. Data input functions are always enabled, i.e.,
data at the bus pins will be stored on every LOW-to-HIGH transition on the clock inputs. This also applies to data I/O (A and B: 8–15) and #2 control pins
