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)
VCC 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.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 5.7 ns tPD max (VCC = 3.3V), 20 µA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±24 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to VCC and OE tied to GND through a resistor: the minimum
value or the resistor is determined by the current-sourcing capability of the
driver.

Note 3: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The “Recom-
mended Operating Conditions” table will define the conditions for actual device operation.
Note 4: IO Absolute Maximum Rating must be observed.
Note 5: Unused (inputs or I/O's) must be held HIGH or LOW. They may not float.
