74F544SPC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74F544SPC is an octal registered transceiver housed in a 24-lead Plastic Dual-In-Line Package (PDIP). It contains two sets of D-type latches for temporary data storage. The device operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of 0°C to +70°C. A outputs sink 24 mA, while B outputs sink 64 mA. Propagation delays vary from 3.0 ns to 18.0 ns depending on the mode and temperature.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains two sets of eight D-type latches for bidirectional data storage
• Provides separate controls for independent inputting and outputting in either direction
• Features distinct current sinking capabilities for A and B output sets

Buffers, Drivers, Receivers, Transceivers Applications

• Temporary data storage in digital systems
• Bidirectional data flow control between bus structures
• Octal register applications requiring independent latch enable and output enable

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type N24C corresponds to the 24-Lead PDIP when sourcing. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for any product change notifications regarding manufacturing site or material composition updates prior to finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with integrated latching is required. Ensure the design accommodates the separate Latch Enable and Output Enable inputs for each direction. Verify that the load conditions do not exceed the specified 24 mA for A outputs or 64 mA for B outputs under all operating temperatures.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74F logic family, characterized by high-speed performance. It serves as a bridge between microprocessors and peripheral devices, allowing data buffering and direction control. The octal configuration reduces pin count compared to using multiple single-bit registers.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for other 74F544 variants from different manufacturers to verify pin compatibility and electrical characteristics. Ensure replacement parts support the same 24-pin PDIP package and meet the required voltage and current specifications.
