Overview
The MC74F240ML1 is an octal buffer and line driver manufactured by onsemi, belonging to the 74F logic family. It features eight inverting outputs with three-state capability, allowing for effective bus-oriented communication systems. The device operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes a 20-pin Small Outline Integrated Circuit (SOIC) package, designated as ML1, suitable for surface-mount applications. This component is designed for high-speed digital signal processing tasks requiring low propagation delay.
Feature Summary
- Provides eight inverting buffer channels with independent output enable controls for bus management.
- Features three-state outputs to prevent bus contention during multi-driver operations.
- Utilizes Schottky-clamped transistor technology to achieve high switching speeds.
Applications
- Bus-oriented memory and address drivers
- Clock distribution circuits
- Data register buffering
Procurement Notes
Verify the specific suffix ML1 corresponds to the SOIC-20 package configuration. Confirm RoHS compliance status as indicated in official documentation, noting that some legacy F-series variants may have different environmental classifications. Ensure the ordering information matches the exact manufacturer part number to avoid substitution errors with similar HC or AC series components.
Selection Notes
Select this component when high-speed performance is required over standard TTL or HC families. The F-series offers faster propagation delays but consumes more power. Consider thermal dissipation requirements due to higher current drive capabilities. Verify that the system voltage aligns strictly with the 5V nominal requirement for optimal noise margins and timing specifications.
Part Context
This part belongs to the 74F (Fast) logic family, known for superior speed compared to standard 74LS devices. It serves as a direct pin-compatible upgrade for applications demanding faster edge rates. The octal configuration reduces board space by integrating eight buffers into a single package, simplifying design complexity for wide data buses.
Replacement Considerations
MC74HC240ML1: Offers lower power consumption but slower speed. MC74AC240ML1: Provides higher speed and wider voltage range. MC74FCT240TLM: Faster CMOS technology with TTL-compatible inputs. Verify electrical characteristics before substituting.
