74ACTQ16240SSCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ16240SSCX is a 16-bit inverting buffer and line driver featuring 3-STATE outputs, housed in a 48-lead Small Shrink Outline Package (SSOP). It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. The device utilizes FACT Quiet Series technology for improved dynamic threshold performance and guaranteed simultaneous switching noise levels. It provides separate control logic for each byte, with outputs capable of sourcing and sinking 24 mA. Propagation delays are specified at a maximum of 7.8 ns under standard load conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Utilizes FACT Quiet Series technology to guarantee quiet output switching and superior dynamic threshold performance.
• Features nibble-controlled architecture allowing independent operation of four bytes or full 16-bit synchronization.
• Provides 3-STATE outputs controlled by separate Output Enable inputs for each nibble.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitters and receivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the SSOP variant, as the TSSOP version carries a different suffix. Confirm that the component is sourced from authorized distributors to ensure authenticity, particularly given the historical Fairchild Semiconductor origin. Check for RoHS compliance status if required by specific manufacturing standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a high-density 16-bit inverting buffer with independent byte control is required. Ensure the design accommodates the 4.5V to 5.5V supply voltage range. Consider the 24 mA drive capability for direct load interfacing. Verify that the SSOP package dimensions fit the available PCB real estate compared to the TSSOP alternative.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACTQ series, which integrates ACT speed with Quiet Series noise reduction features. The 74ACTQ16240 serves as the 16-bit counterpart to the 8-bit 74ACTQ240. Originally manufactured by Fairchild Semiconductor, these components are designed for high-performance digital systems requiring low noise and precise timing control.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACTQ16240MTD is a pin-compatible alternative utilizing a 48-Lead Thin Shrink Small Outline Package (TSSOP) instead of the SSOP form factor. Both variants share identical electrical specifications and functionality.

Buffers, Drivers, Receivers, Transceivers FAQ

How is the 3-STATE control managed in the 74ACTQ16240?

The device is nibble-controlled, meaning it has four separate Output Enable (OE_n) inputs. Each input controls one byte (4 bits), allowing independent tri-stating of each nibble or shorting them together for full 16-bit operation.

What is the significance of the 'Quiet Series' technology in this device?

FACT Quiet Series technology guarantees reduced simultaneous switching noise levels and improved dynamic threshold performance, ensuring stable signal integrity during high-speed transitions.
