74LCX16240
Low Voltage 16-Bit Inverting Buffer/Line Driver
with 5V Tolerant Inputs and Outputs
General Description
The LCX16240 contains sixteen inverting buffers with
3-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus-oriented transmit-
ter/receiver. The device is nibble controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The LCX16240 is designed for low voltage (2.5V or 3.3V)
VCC applications with capacity of interfacing to a 5V signal
environment.
The LCX16240 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 to 3.6V VCC specifications provided
s 4.5 ns tPD max (VCC 3.3V), 20 PA ICC max
s Power down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s
r24 mA output drive (VCC 3.0V)
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 through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
