SN74HCT240PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT240PWR is an octal buffer and line driver manufactured by Texas Instruments. It belongs to the 74HCT logic series, designed for high-speed CMOS applications with TTL-compatible inputs. The device features two independent buffers, each handling four bits of data. It operates within a supply voltage range of 4.5V to 5.5V and provides three-state outputs. The component is housed in a 20-TSSOP surface-mount package with a width of 4.40mm. It supports a wide operating temperature range from -40°C to 85°C and delivers output currents of 6mA for both high and low states.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel configuration, as variations exist between cut tape, Digi-Reel, and standard reel packaging. Ensure the RoHS3 compliance status matches project requirements. Confirm the moisture sensitivity level (MSL 1) and storage conditions if the component has been exposed to humid environments prior to assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverted octal buffer with three-state outputs is required in a TSSOP-20 package. It is suitable for designs needing 5V operation with TTL input thresholds. Consider alternative packages like SOIC or PDIP if surface mount constraints are not applicable. Verify that the 6mA drive current meets the load requirements of the connected circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the broader 74HCT family of logic ICs, which bridges the gap between older TTL standards and modern CMOS technologies. The SN74HCT240 specifically serves as an inverting buffer, contrasting with non-inverting counterparts like the SN74HCT244. It is widely used in digital systems where signal integrity and bus isolation are critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN74HCT240PWRE4 and SN74HCT240PWRG4, which share identical electrical characteristics and pinouts. Other compatible parts in the same series may offer different packaging options but maintain functional equivalence.
