74ACT16374DLR

16位D型边沿触发触发器具有三态输出 16-BIT D-TYPE EDGE-TRIGGERED FLIP-FLOPS WITH 3-STATE OUTPUTS

The SN54ACT16374 and 74ACT16374 are 16-bit edge-triggered D-type flip-flops with 3-state outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

These devices 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.

An output-enable input OE can be used to place the outputs in either a normal logic state high or low logic levels or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state provides the capability to drive bus lines in a bus-organized system without need for interface or pullup components. OE does not affect the 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.

The 74ACT16374 is packaged in ’s shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit board area.

The SN54ACT16374 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT16374 is characterized for operation from -40°C to 85°C.
