74HC374PW,118

Overview

The Nexperia 74HC374PW,118 is an octal D-type flip-flop with 3-state outputs housed in a 20-TSSOP package. It operates on a supply voltage range of 2.0 V to 6.0 V and supports a maximum clock frequency of 130 MHz. The device features positive-edge triggering and non-inverting outputs. Key electrical parameters include a maximum propagation delay of 10.4 ns at 5 V with 50 pF load, output current capability of 8 mA for both high and low states, and a static current of 4 µA. It functions within a temperature range of -40 °C to +125 °C.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering mechanism
• Three-state outputs designed for efficient bus-oriented applications
• High noise immunity and robust latch-up performance exceeding JESD 78 standards

Applications

• Bus-oriented data storage systems
• Parallel-to-serial conversion circuits
• General-purpose digital logic registers

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration matches project requirements. Confirm that the 20-TSSOP package dimensions align with the designated PCB footprint. Check RoHS compliance status against environmental regulations applicable to the target market. Ensure input voltage levels remain within the specified CMOS limits to prevent interface issues.

Selection Notes

Select this component when an octal register with tri-state control is required for high-speed data handling. The wide supply voltage range allows compatibility with various logic families. Consider the 130 MHz clock limit for timing-critical designs. The TSSOP package offers a compact solution for space-constrained layouts while maintaining thermal stability across industrial temperature ranges.

Part Context

This part belongs to the 74HC series of high-performance silicon gate CMOS devices. It provides standard octal flip-flop functionality with enhanced speed compared to legacy HC variants. The 74HC374 is functionally similar to latches but utilizes edge-triggering for precise data capture. It is widely used in microprocessor-based systems for temporary data holding and address latching operations.

Replacement Considerations

Direct substitutes include the 74HCT374PW,118 for TTL-compatible input levels. Other compatible options are the SN74HC374 from Texas Instruments or the MC74HC374 from ON Semiconductor. Verify pinout compatibility and output drive strength before swapping manufacturers.
