74LCX16500
Low Voltage 18-Bit Universal Bus Transceivers with
5V Tolerant Inputs and Outputs
General Description
These 18-bit universal bus transceivers combine D-type
latches and D-type flip-flops to allow data flow in transpar-
ent, latched, and clocked modes.
Data flow in each direction is controlled by output-enable
(OEAB and OEBA), latch-enable (LEAB and LEBA), and
clock (CLKAB and CLKBA) inputs.
The LCX16500 is designed for low voltage (2.5V or 3.3V)
VCC applications with the capability of interfacing to a 5V
signal environment.
The LCX16500 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s 6.0 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 5: 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 6: IO Absolute Maximum Rating must be observed.
Note 7: Unused (inputs or I/O's) must be held HIGH or LOW. They may not float.
