- Full Parallel Access for Loading
- Buffered Control Inputs
- Package Options Include Plastic Small-Outline (SOIC) and Shrink Small-Outline (SSOP) Packages, Ceramic Chip Carriers, and Plastic and Ceramic DIPs
These 8-bit flip-flops feature 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.
The eight flip-flops of the ´F374 are edge-triggered D-type flip-flops. On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels that were set up at the data (D) inputs.
A buffered output enable () input can be used to place the eight outputs in either
a normal logic state (high or low) 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
provide the capability to drive bus lines without need for interface
or pullup components.
The output enable ()
input 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.
The SN74F374 is available in TI's shrink small-outline package (DB), which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54F374 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74F374 is characterized for operation from 0°C to 70°C.
