SN74ALVC16374

This SN74ALVC16374 16-bit edge-triggered D-type flip-flop is designed for 3.3-V V_CC operation; it is tested at 2.5-V, 2.7-V, and 3.3-V V_CC.

The SN74ALVC16374 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock (CLK) input, the Q outputs of the flip-flop take on the logic levels set up at the data (D) inputs. OE) can be used to place the eight outputs in either a normal logic state (high- or low-logic levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive of SN74ALVC16374 provide the capability to drive bus lines without need for interface or pullup components. OE does not affect internal operations of the flip-flop. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
