74FCT823ATSOG

Overview

The IDT74FCT823ATSOG is a high-speed, low-power CMOS D flip-flop manufactured using advanced dual metal technology. It features nine positive-edge-triggered functions housed in a 24-pin SOIC package. The device operates within a supply voltage range of 4.75V to 5.25V and supports an industrial temperature range from -40°C to +85°C. Key electrical parameters include a typical propagation delay of 7.5 ns at 5V with 50 pF load capacitance, balanced output drivers capable of ±24mA, and maximum input/output leakage currents of 1µA. It is designed as a replacement for ABT logic functions.

Feature Summary

• High-speed, low-power CMOS technology suitable for temporary data storage
• Balanced output drivers reduce system switching noise
• Low input and output leakage characteristics
• Transparent latch functionality for memory address and I/O port implementation

Applications

• Memory address latches
• I/O ports
• Bus drivers

Procurement Notes

Verify the specific suffix ATSOG against the manufacturer's current product lifecycle status, as legacy FCT series components may be subject to discontinuation notices or production end-of-life (EOL) notifications. Confirm RoHS compliance and moisture sensitivity level requirements prior to procurement. Cross-reference datasheet revisions to ensure pinout and electrical specifications remain consistent with the target design requirements.

Selection Notes

Select this component when a 9-bit positive-edge triggered D flip-flop is required in a 24-pin surface-mount package. Ensure the design accommodates the 5V nominal supply voltage and industrial temperature range. Consider the 7.5 ns propagation delay and 50 pF load capability for timing analysis. Verify that the SOIC-24 footprint matches the PCB layout constraints and that the output drive strength meets the downstream circuit loading requirements.

Part Context

This part belongs to the IDT 74FCT family of fast CMOS logic devices. The 74FCT823 specifically provides nine D-type flip-flops with positive edge triggering. It serves as a high-performance alternative to older ABT logic families, offering improved speed and lower power consumption while maintaining compatible pinouts and functionality for direct upgrades in existing designs.
