74LCX16240 Low Voltage 16-Bit Inver ting Buffer/Line Driver with 5V Tolera nt Inputs and Outputs
74LCX16240
Low Voltage 16-Bit Inverting Buffer/Line Dri ver
with 5V Tolerant Inputs and Outputs
General Descript ion
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- S TATE control inpu ts which can be sh orted
together for full 16-bit operation.
The LCX16240 is designed for low voltage (2.5V or 3.3V)
VCC applicat ions w ith capacity of interfa cing to a 5V sig nal
environment.
The LCX16240 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.

Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to VCC throug h a pu ll-up res istor: the m inimu m value o r the
resistor is determined by the current-sourcing capability of the driver.
