18-BIT UNIVERSAL BUS DRIVER WITH 3-STATE OUTPUTSThis 18-bit universal bus driver SN74ALVCH16834 is designed for
1.65-V to 3.6-V VCC operation.
Data flow from A to Y is controlled by the
output-enable (OE) input. The device operates in
the transparent mode when the latch-enable (LE)
input is low. The A data is latched if the Clock (CLK)
input is held at a high or low Logic level. If LE is
high, the A data is stored in the latch Flip-Flop on
the low-to-high transition of CLK. When OE is
high, the outputs are in the high-impedance state.
To ensure the high-impedance state during power
up or power down, OE should be tied to VCC
through a 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 data inputs at a valid Logic level.
The SN74ALVCH16834 is characterized for
operation from 40C to 85C. By Texas Instruments
