74LCX16652 Low Voltage Transceiver/Register with 5V Tolerant Inputs and Outputs
February 1994
Revised April 2001
74LCX16652
Low Voltage Transceiver/Register
with 5V Tolerant Inputs and Outputs
General Description
The LCX16652 contains sixteen non-inverting bidirectional
bus transceivers with 3-STATE outputs providing multi-
plexed transmission of data directly from the input bus or
from the internal registers. Data on the A or B bus will be
clocked into the registers as the appropriate clock pin goes
to the HIGH logic level. Output Enable pins (OEAB, OEBA)
are provided to control the transceiver function (see Func-
tional Description).
The LCX16652 is designed for low-voltage (2.5V or 3.3V)
V
CC
applications with capability of interfacing to a 5V signal
environment.
The LCX16652 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.

Note 1:
To ensure the high-impedance state during power up or down, OE
should be tied to V
CC
and OE tied to GND through a resistor: the minimum
value or the resistor is determined by the current-sourcing capability of the
driver.
