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)
V
CC
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.

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.
