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.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V V_CC specifications provided
s 6.0 ns t_PD max (V_CC = 3.3V), 20 µA I_CC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s ±24 mA output drive (V_CC = 3.0V)
s Uses patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V
s Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA)
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.
