Product Description

The SN74S374 is a set of eight D-type flip-flops featuring direct clear (CLR) and clock (CLK) inputs. Information on the data (D) input is transferred to the Q output on the positive-going edge of the CLK pulse. The clear function is synchronous, and a low level at the CLR input sets all outputs low, regardless of the levels of the other inputs.

Each flip-flop has independent D, CLK, and CLR inputs and Q and Q̅ outputs. The outputs can drive up to 10 LS-TTL loads, and the SN74S374 is characterized for operation from 0°C to 70°C. This device is typically used in buffer/storage registers, shift registers, and as part of data control systems.

The SN74S374's tri-state outputs can be set to a high impedance (off) state, effectively disconnecting the output from the rest of the circuit. This feature makes it suitable for interfacing with bus-structured systems where multiple outputs can connect to a common bus without interference.

Applications

Common applications for the SN74S374 include:

• Data storage and transfer
• System synchronization
• Bus drivers
• Interface buffering
• Shift registers

With its robust design and versatile functionality, the SN74S374 from Texas Instruments is an essential component for designers looking to implement reliable and efficient data handling capabilities in their digital systems.
