74FR16245SSC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74FR16245SSC is a 16-bit bus transceiver featuring three-state outputs and separate direction control pins for each byte. It operates within the FR/FAST logic series, utilizing an SSOP-48 package with 48 terminals. The device supports a maximum operating temperature of 70 °C and a minimum of unspecified values in available records. Key electrical characteristics include a propagation delay of 8.4 ns, TTL input levels, and CMOS output levels. Output drive capabilities are specified at 24 mA for both high and low states.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides sixteen non-inverting bidirectional buffers designed for bus-oriented applications.
• Features separate control pins for each byte to manage data flow direction independently.
• Delivers high current sinking capability on both A and B ports.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented digital systems requiring 16-bit data transfer
• Memory interface circuits with independent byte control
• High-speed logic applications within the FAST family

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific minimum operating temperature as the source data lists it as empty or unknown. Confirm the Reach Compliance Code status, which is marked as unknown in the provided specifications. Ensure the SSOP package dimensions align with design constraints, noting the length is specified as 15.875 mm. Cross-reference the manufacturer details between Rochester Electronics and Fairchild to ensure component authenticity and sourcing accuracy.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit bidirectional data paths with individual byte direction control. The FR/FAST series offers high-speed performance suitable for demanding bus architectures. Consider the 70 °C maximum operating temperature limit when evaluating thermal management requirements. Verify compatibility with TTL input levels and CMOS output interfaces to ensure proper signal integrity across the system.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74FR16245 family of 16-bit transceivers manufactured by Rochester Electronics, originally based on Fairchild Semiconductor technology. The SSC suffix indicates the SSOP surface-mount package variant. It serves as a specialized solution for complex bus systems where granular control over data direction per byte is necessary, distinguishing it from devices with common direction controls.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The Texas Instruments 74ACT16245DL is listed as a possible replacement. However, verify that the ACT series voltage ranges and speed characteristics match the original FR series requirements. Ensure the pinout compatibility remains consistent between the SSOP packages of both components before implementation.
