Frequently Asked Questions
What logic function does SNV54LS374J perform and how many bits does it handle?
The SNV54LS374J is an 8-bit octal D-type flip-flop register. All 8 flip-flops share a common positive-edge-triggered clock input, so data on all 8 D inputs is latched simultaneously on the rising clock edge, providing synchronized 8-bit parallel data capture and storage in a single device.
What operating temperature range does SNV54LS374J support, and why does this matter for military designs?
The SNV54LS374J operates from -55°C to 125°C, meeting military-grade temperature requirements. This range ensures reliable logic operation in avionics, ground vehicles, and shipboard electronics where ambient temperatures can swing far beyond the 0°C to 70°C range of commercial-grade devices, preventing timing failures in extreme environments.
How do the 3-state outputs of SNV54LS374J support multi-device bus architectures?
The SNV54LS374J includes a common active-low output-enable (OE) pin that places all 8 outputs into a high-impedance state when asserted. This allows multiple SNV54LS374J devices to be connected to a shared 8-bit data bus, with only one device driving the bus at a time, preventing bus contention and enabling standard multi-master architectures.
What is the propagation delay specification for SNV54LS374J and how does it affect clocked system timing?
As part of the 54LS logic family, the SNV54LS374J has a typical clock-to-output propagation delay of approximately 20 ns, with a maximum setup time of 20 ns and a hold time of 5 ns. These parameters must be met relative to the system clock to guarantee valid data latching and are critical inputs to static timing analysis of digital pipeline stages.
