DM74LS123M

Multivibrators Overview

The DM74LS123M is a dual retriggerable monostable multi-vibrator manufactured by onsemi, housed in a 16-lead Small Outline Integrated Circuit (SOIC) package. It features three inputs per channel for flexible triggering options and includes clear and complementary outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to +70°C. Key electrical characteristics include a low-level output current of 8 mA, a high-level output current of -0.4 mA, and propagation delays ranging from 33 ns to 56 ns depending on the input path.

Multivibrators Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package marking matches the M16A designation for the SOIC variant. Check datasheet revisions for any updates to electrical parameters or ordering information before finalizing procurement specifications.

Multivibrators Selection Notes

Select this component when dual independent one-shot timing functions are required in a compact surface-mount form factor. Ensure external timing components meet leakage and capacitance requirements to maintain accuracy. Verify compatibility with existing TTL logic levels and power supply constraints.

Multivibrators Part Context

This part belongs to the DM74LS series of logic integrated circuits produced by onsemi. It is functionally compatible with standard 74LS monostable multivibrators but offers specific pinout and performance characteristics defined by the manufacturer's datasheet.

Multivibrators Replacement Considerations
