74ABT16374CSSCX

Flip Flops Overview

The onsemi 74ABT16374CSSCX is a dual 8-bit D-type flip-flop with positive-edge triggering, housed in a 48-SSOP package. It operates within a 4.5V to 5.5V supply range and features tri-state, non-inverting outputs capable of 32mA high and 64mA low drive currents. The device exhibits a maximum propagation delay of 6.2ns at 5V with 50pF load and supports clock frequencies up to 150 MHz. Static current consumption is specified at 2 mA, with an input capacitance of 5 pF. It functions reliably across an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Dual-channel architecture providing two independent 8-bit D-type flip-flops within a single integrated circuit.
• Positive-edge triggered operation ensures data capture occurs precisely at the rising edge of the clock signal.
• Tri-state output configuration allows for bus sharing and efficient interfacing with high-capacitance loads.

Flip Flops Applications

• High-speed parallel data storage and buffering in digital communication systems
• Interface logic between microprocessors and peripheral devices requiring precise timing control
• State machine implementation in complex digital logic circuits

Flip Flops Procurement Notes

This component is officially designated as obsolete and no longer manufactured by onsemi. Procurement must rely exclusively on verified replacement part numbers from other manufacturers. Verify that substitute components match the original pinout, voltage specifications, and functional requirements before integration into production designs.

Flip Flops Selection Notes

Designers should prioritize replacements that maintain the 48-pin SSOP form factor and 4.5V–5.5V operating range. Ensure selected substitutes support the required 150 MHz clock frequency and 6.2ns propagation delay characteristics. Confirm compatibility with existing PCB layouts and thermal management strategies to avoid redesign efforts.

Flip Flops Part Context

The 74ABT16374 belongs to the ABT logic family, known for advanced BiCMOS technology offering high speed and low power consumption. This specific variant integrates dual 8-bit registers, distinguishing it from single-element counterparts. Its design targets applications demanding reliable data latching with minimal latency in dense surface-mount configurations.

Flip Flops Replacement Considerations

SN74ABT16374ADGGR, SN74ABT16374ADL, and SN74ABT16374ADLR are confirmed parameter-equivalent or similar substitutes from Texas Instruments. CY74FCT16374CTPVC is also listed as a comparable alternative. Verify electrical parameters against the original datasheet prior to adoption.
