What are the key features of SN54HC377J?
- Octal D flip-flop with common clock enable operating up to 16 MHz from 2 V to 6 V supply
- Military-grade ceramic DIP-20 package rated from -55°C to 125°C for harsh-environment and aerospace designs
- Hold-mode feature retains output state when clock enable is deasserted, reducing switching noise in bus applications
What is SN54HC377J used for?
The SN54HC377J is designed for bus interface and data register applications in military, aerospace, and industrial systems where the -55°C to 125°C operating range and ceramic package reliability are mandatory. Its octal width and clock-enable input make it suitable for latching parallel data buses in ruggedized embedded controllers and FPGA interface boards. Designers also use it in memory address registers and I/O expansion circuits requiring synchronized, noise-immune data capture at up to 16 MHz.

Frequently Asked Questions
What operating frequency and supply range does the SN54HC377J support?
The SN54HC377J operates up to 16 MHz with a supply voltage range of 2 V to 6 V. It delivers a guaranteed output drive of 5.2 mA at V_OL, making it compatible with both 3.3 V and 5 V HC logic systems across the full -55°C to 125°C military temperature range.
Which applications benefit most from the SN54HC377J ceramic DIP-20 package?
Applications in aerospace avionics, military communications, and industrial control systems benefit most because the ceramic DIP-20 package withstands -55°C to 125°C and offers superior hermetic sealing versus plastic packages. With 8 flip-flop channels in 20 pins, it efficiently stores parallel bus data in ruggedized environments.
How does the hold-mode feature compare to a standard octal latch for bus designs?
Unlike a transparent latch, the SN54HC377J's clock enable holds all 8 outputs at their last state when the enable line is low, preventing glitch propagation on data buses. With a load capacitance rating of 50 pF per output and 16 MHz operation, it outperforms many older CMOS latches in noise-sensitive military bus architectures.
