It stores eight bits of data in parallel, making it a straightforward choice for buffering, temporary storage, or pipeline registers in 5V and 3.3V logic systems. The 20-pin DIP package (0.300\" body) fits through-hole boards and breadboards, common in prototyping, industrial control panels, and legacy equipment repairs. ## 64 MHz clock and 27 ns propagation delay — timing fit Rated for a clock frequency of 64 MHz, this flip-flop handles synchronous data transfers. The maximum propagation delay is 27 ns at 6 V with a 50 pF load. ## Industrial temperature grade and package Rated for -40°C to 85°C ambient, this part suits factory-floor controllers, outdoor telecom cabinets, and HVAC equipment where the board sees temperature swings. The 20-pin PDIP package (20-DIP, 0.300\" wide) is through-hole, easy to hand-solder or socket, and remains a standard footprint for maintenance spares and retrofit boards. ## Lifecycle and sourcing reality TI lists the SN74HC377N as Active and ROHS3 compliant.","metaTitle":"SN74HC377N D-Type Flip-Flop, 8-Bit, 64 MHz, 20-DIP","metaDescription":"TI SN74HC377N 8-bit D-type flip-flop, 64 MHz clock, 2V-6V supply, -40°C to 85°C, 20-DIP.

For an 8-bit drop-in, stick with the 74HC377 family; the LS variant is not a direct pin-for-pin replacement due to bit count and supply differences."},{"question":"Can SN74HC377N be used with 5V supply?","answer":"Yes, the SN74HC377N operates over a 2 V to 6 V supply range, so 5 V is well within specification. At 5 V the propagation delay will be slightly higher than the 27 ns figure quoted at 6 V, but still suitable for most 5 V logic systems."},{"question":"What is the lead time for SN74HC377N from major distributors?","answer":"Lead time is confirmed at quote time against an RFQ.
