SN74HC377NS

Flip Flops Overview

The SN74HC377NS is an octal D-type flip-flop with clock enable, manufactured by Texas Instruments. It belongs to the HC logic family and features CMOS inputs and outputs. The device operates within a supply voltage range of 2 V to 6 V and supports through-hole installation in a 20-pin PDIP package. It includes eight independent D-type flip-flops with non-inverting outputs. Key electrical parameters include a maximum propagation delay of 160 ns at 2 V and output drive currents of ±5.2 mA. The component functions reliably across an operating temperature range of -40 °C to +85 °C.

Flip Flops Procurement Notes

Verify the specific suffix 'NS' against official Texas Instruments documentation to confirm the exact package variant and manufacturing origin. Ensure that the procurement channel provides valid RoHS compliance certificates. Confirm that the supplier source matches the manufacturer's authorized distribution network to guarantee component authenticity and traceability.

Flip Flops Selection Notes

Select this component when an octal edge-triggered storage solution with clock enable is required. The HC series offers standard speed suitable for general digital logic applications. Consider the PDIP-20 package for prototyping or through-hole designs. Verify that the 2 V to 6 V supply range aligns with the system's power architecture and that the 160 ns delay meets timing requirements.

Flip Flops Part Context

The SN74HC377NS is part of the broader SN74HC377 family of octal D-type flip-flops. This family is designed for high-speed CMOS operations and is compatible with standard TTL logic levels. The 'N' suffix typically denotes the PDIP package, while 'S' may indicate specific tape-and-reel or regional variants. It serves as a fundamental building block for sequential logic circuits requiring parallel data latching.

Flip Flops Replacement Considerations

SN74HC377N (PDIP-20), SN74HC377DW (SOIC-20), SN74HC377NSR (SOIC-20 Reel). Verify pinout compatibility and package dimensions before substitution.
