They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The ’ABT162841 devices can be used as two 10-bit latches or one 20-bit latch. While the latch-enable (1LE or 2LE) input is high, the Q outputs of the corresponding 10-bit latch follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. 1 56 2 55 3 54 4 53 5 52 6 51 7 50 8 49 9 48 10 47 11 46 12 45 13 44 14 43 15 42 16 41 17 40 18 39 19 38 20 37 21 36 22 35 23 34 24 33 25 32 26 31 27 30 28 29 1LE 1D1 1D2 GND 1D3 1D4 VCC 1D5 1D6 1D7 GND 1D8 1D9 1D10 2D1 2D2 2D3 GND 2D4 2D5 2D6 VCC 2D7 2D8 GND 2D9 2D10 2LE ORDERING INFORMATION PACKAGE† TA −40°C −40 C to 85 85°C C −55°C to 125°C ORDERABLE PART NUMBER TOP-SIDE MARKING Tube SN74ABT162841DL Tape and reel SN74ABT162841DLR TSSOP − DGG Tape and reel SN74ABT162841DGGR CFP − WD Tube SNJ54ABT162841WD SSOP − DL ABT162841 ABT162841 SNJ54ABT162841WD † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.

In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The outputs, which are designed to sink up to 12 mA, include equivalent 25-Ω series resistors to reduce overshoot and undershoot. These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict. To ensure the high-impedance state during power up or power down, OE shall be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. OE does not affect the internal operation of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
