POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
When an output function is disabled, the input function is still enabled and may be used to store and transmit
data. Only one of the two buses, A or B, may be driven at a time.
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 VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74LVT16646 is available in TI’s shrink small-outline (DL) and thin shrink small-outline (DGG) packages,
which provide twice the I/O pin count and functionality of standard small-outline packages in the same
printed-circuit-board area.
The SN54LVT16646 is characterized for operation over the full military temperature range of – 55
°C to 125°C.
The SN74LVT16646 is characterized for operation from – 40
°C to 85°C.

† The data output functions may be enabled or disabled by various signals at OE and DIR. Data input functions are always enabled; i.e., data at
the bus pins will be stored on every low-to-high transition of the clock inputs.
