DM74LS374WM

Overview

The DM74LS374WM is an octal D-type edge-triggered flip-flop manufactured by onsemi. It features eight non-inverting outputs with three-state capability, designed for driving highly-capacitive or low-impedance loads. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum clock frequency of 20MHz. Propagation delay is specified at 27ns at 5V. It is housed in a 20-SOIC surface-mount package with dimensions of 13mm length and 2.34mm height. Operating temperature ranges from 0°C to 70°C.

Feature Summary

Octal D-type edge-triggered flip-flop configuration
Three-state non-inverting outputs for bus-driven systems
Designed for direct connection to bus lines without interface components

Applications

Buffer registers
I/O ports implementation
Bidirectional bus drivers
Working registers

Procurement Notes

Verify the specific manufacturer origin (onsemi vs Fairchild) as legacy designations may vary. Confirm RoHS compliance status as historical data indicates potential variations. Ensure the SOIC package width matches the 7.50mm specification required for your PCB footprint. Check for any PCN notifications regarding manufacturing site changes that might affect long-term availability.

Selection Notes

Select this component when an octal register with three-state outputs is required for bus-oriented architectures. It is suitable for applications needing high-impedance states to connect directly to bus lines without pull-up components. Consider the 20MHz clock limit and 27ns propagation delay against system timing requirements. Verify compatibility with standard TTL logic levels if interfacing with other LS series devices.

Part Context

This part belongs to the 74LS family of bipolar logic circuits, specifically the DM74LS374 series. It is functionally related to the DM74LS373 transparent latch but utilizes edge-triggering instead of level-sensitive latching. The WM suffix denotes the 20-SOIC surface-mount package variant. It shares output drive characteristics with other LS series buffers like the DM74LS244WM.
