DESCRIPTION
This 18-bit buffer and line driver is designed for
1.65-V to 3.6-V V
operation.
CC
This SN74ALVCH16825 improves the performance
and density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and transmitters.
The device can be used as two 9-bit buffers or one
18-bit buffer. It provides true data.
The 3-state control gate is a 2-input AND gate with
active-low inputs so that if either output-enable (OE1
or OE2) input is high, all nine affected outputs are in
the high-impedance state.
To ensure the high-impedance state during power up
or power down, OE should be tied to V
pullup resistor; the minimum value of the resistor is
determined by the current-sinking capability of the
driver.
Active bus-hold circuitry is provided to hold unused or floating inputs at a valid logic level.
The SN74ALVCH16825 is characterized for operation from -40 C to 85 C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.
