description
The SN74LVT16835 is an 18-bit universal bus
driver designed for low-voltage (3.3-V) V
CC
operation, but with the capability to provide a TTL
interface to a 5-V system environment.
Data flow from A to Y is controlled by the
output-enable (OE) input. This device operates in
the transparent mode when the latch-enable (LE)
input is high. The A data is latched if the clock (CLK) input is held at a high or low logic level. If LE is low, the
A-bus data is stored in the latch/flip-flop on the low-to-high transition of the clock. When OE is high, the outputs
are in the high-impedance state.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74LVT16835 is available in TI’s shrink small-outline (DL) and thin shrink small-outline (DGG) packages,
which provide twice the input/output (I/O) pins and functionality of standard small-outline packages in the same
printed circuit board area.
The SN74LVT16835 is characterized for operation from –40
°
C to 85
°
C.
