74LCX16501
18-Bit Universal Bus Transceivers with 5V Tolerant
Inputs and Outputs
General Description
The LCX16501 is an 18-bit universal bus transceiver com-
bining D-type latches and D-type flip-flops to allow data
flow in transparent, 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 LCX16501 is designed for low voltage (2.5V or 3.3V)
VCC applications with capability of interfacing to a 5V signal
environment.
The LCX16501 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 9: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL), or LOW-to-HIGH (tOSLH).
