This 18-bit universal bus transceiver is designed for 2.7-V to3.6-V VCC operation.
The SN74ALVC162601 combines D-type latches and D-type flip-flopsto allow data flow in transparent, latched, and clocked modes.
Data flow in each direction is controlled by output-enable ( and ), latch-enable (LEAB and LEBA),and clock (CLKAB and CLKBA) inputs. The clock can be controlled bythe clock-enable (
and ) inputs. For A-to-B data flow, thedevice operates in the transparent mode when LEAB is high. When LEABis low, the A data is latched if CLKAB is held at a high or low logiclevel. If LEAB is low, the A-bus data is stored in thelatch/flip-flop on the high-to-low transition of CLKAB. Output enable
is active low.When
is low, theoutputs are active. When
ishigh, the outputs are in the high-impedance state.
Data flow for B to A is similar to that of A to B but uses , LEBA, CLKBA, and .
The B-port outputs, include 25-
series resistors to reduce overshoot and undershoot.
The SN74ALVC162601 is available in TI's shrink small-outline (DL)and thin shrink small-outline (DGG) packages, which provide twice theI/O pin count and functionality of standard small-outline packages inthe same printed-circuit-board area.
The SN74ALVC162601 is characterized for operation from -40°Cto 85°C.
