74AHC377PW,118

Overview

The 74AHC377PW,118 is an octal D-type flip-flop with clocked outputs manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 5.5 V and features non-inverting outputs. The device is housed in a 20-TSSOP package and supports a maximum clock frequency of 200 MHz. Propagation delay is specified at 11 ns under standard conditions. It includes clamp diodes on inputs for interfacing with voltages exceeding VCC and provides ESD protection compliant with ANSI/ESDA/JEDEC standards.

Feature Summary

• Octal D-type flip-flop architecture with eight independent storage elements
• Clocked output design ensures synchronized data transfer and reduces bus contention
• Wide operating voltage compatibility supporting both 3.3 V and 5 V logic systems
• High noise immunity and robust latch-up performance for reliable operation

Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching in microprocessor-based systems
• I/O port expansion for digital interfaces
• Timing control and synchronization in communication modules

Procurement Notes

Verify the specific ordering code suffix to ensure correct packaging configuration, as variations exist between tape-and-reel and cut-tape formats. Confirm that the procurement channel sources directly from authorized Nexperia distributors to guarantee component authenticity and traceability. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the supplier provides valid datasheets matching the exact part number revision before placing orders.

Selection Notes

Select this component when an octal storage element with synchronized output timing is required. The AHC series offers superior speed compared to standard HC devices while maintaining CMOS power efficiency. Verify that the system voltage falls within the 2.0 V to 5.5 V operational range. Consider the 20-TSSOP package dimensions for PCB layout constraints. Ensure input signal levels are compatible with CMOS thresholds or utilize HCT variants if TTL levels are necessary.

Part Context

This part belongs to the Nexperia 74AHC family of high-speed CMOS logic devices. It implements the standard 74AHC377 function code, providing octal D-type flip-flops with clocked outputs. The PW suffix indicates the 20-TSSOP surface-mount package. It is designed for applications requiring high-speed data storage with minimal propagation delay in digital logic systems.

Replacement Considerations

Direct functional equivalents include the 74AHCT377PW,118 for TTL-compatible input requirements. For lower voltage applications, the 74LVC377PW,118 may be suitable. Cross-voltage replacements require verification of input/output voltage levels and propagation delay specifications against system requirements.
