74HC377PW,112

Overview

The 74HC377PW,112 is an octal D-type edge-triggered flip-flop manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and features non-inverting outputs. The device is housed in a 20-TSSOP surface-mount package with a width of 4.40 mm. Key electrical specifications include a maximum propagation delay of 13 ns at 5 V with a 50 pF load, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It supports a wide operating temperature range from -40 °C to +125 °C.

Feature Summary

• Octal D-type positive-edge triggered flip-flop architecture
• Non-inverting single-ended output configuration
• Wide supply voltage compatibility from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation

Applications

• Parallel data storage in digital systems
• Shift register construction
• Bus interface buffering
• Timing control circuits

Procurement Notes

Verify the specific suffix '112' against the manufacturer's latest datasheet to confirm packaging type, as distribution listings may vary between tube and reel formats. Ensure the component meets AEC-Q100 requirements if automotive qualification is necessary, as standard HC series parts may not carry this certification unless explicitly stated. Confirm RoHS compliance status for environmental regulations.

Selection Notes

Select this component when an octal storage element with edge-triggering is required rather than latching behavior found in transparent latches. The 74HC series offers CMOS input levels suitable for general-purpose logic interfacing. Consider the 74HCT variant if TTL input levels are mandatory for system compatibility. Evaluate the 20-TSSOP package constraints for PCB layout space and thermal management requirements.

Part Context

This part belongs to the Nexperia 74HC family of high-speed CMOS logic devices. The 74HC377 specifically provides eight independent D-type flip-flops in a single package. It differs from the 74HC373 latch by using clock edge triggering instead of level transparency. The PW suffix indicates the TSSOP plastic weak leadless small outline package.

Replacement Considerations

Public confirmed substitute part numbers: 74HC377PW,118 (Nexperia, different packaging). Cross-family alternatives like 74AHCT377 or 74LVC377 require voltage level and speed verification.
