What are the key features of SNV54HC373J?
- Octal 8-bit transparent latch with 3-state outputs enabling direct connection to shared data buses without bus contention
- High-speed CMOS HC-family logic operating from 2 V to 6 V supply with propagation delay under 20 ns at 5 V
- Ceramic DIP package rated for extended temperature ranges and vibration environments required in military and aerospace systems
What is SNV54HC373J used for?
SNV54HC373J is used in military, aerospace, and high-reliability industrial systems where 8-bit data bus buffering and latching must withstand wide temperature extremes and harsh vibration environments. It suits address and data bus demultiplexing in ruggedized embedded controllers and FPGA interface boards that require ceramic package reliability. The 3-state output control also makes it useful in multi-master bus architectures where multiple drivers must share a single 8-bit data bus without contention.

Frequently Asked Questions
How many latch bits does SNV54HC373J provide, and how are the outputs controlled?
SNV54HC373J integrates 8 D-type transparent latch bits, each holding its input value when the latch enable goes low. A shared output-enable pin tri-states all 8 outputs simultaneously, allowing the device to connect directly to an 8-bit bus alongside other drivers without causing contention when the SNV54HC373J is deselected.
What supply voltage range does SNV54HC373J support, and at what speed does it operate?
SNV54HC373J operates across a 2 V to 6 V supply range consistent with the HC high-speed CMOS family. At 5 V, HC-family devices typically achieve propagation delays below 20 ns, enabling data bus latching in embedded systems clocked at tens of MHz without introducing significant timing margin penalties.
Why is a ceramic DIP package important for SNV54HC373J in military applications?
Ceramic DIP packages offer hermetic sealing that prevents moisture ingress under the MIL-STD-883 test conditions specified for military electronics. Ceramic also withstands junction temperatures beyond 125°C and survives shock and vibration levels encountered in avionics and ground-vehicle electronics, where plastic DIP packages risk delamination and bond-wire fatigue.
In a bus-multiplexed system, how does SNV54HC373J help with address latching on an 8-bit microcontroller?
Many 8-bit microcontrollers multiplex address and data on the same 8 pins to save I/O count. SNV54HC373J captures the 8 address bits on the rising ALE strobe and holds them stable on its 8 outputs for the remainder of the bus cycle, allowing the multiplexed bus to carry data during the following phase without corrupting the latched address value used by memory and peripheral decoders.
