CY74FCT373TSOCTG4

Latches Overview

The CY74FCT373TSOCTG4 is an octal transparent D-type latch manufactured by Texas Instruments. It features eight latches with three-state outputs, designed for bus-organized applications within the FCT logic series. The device operates at a supply voltage of 5V and accepts TTL-compatible inputs. Key electrical characteristics include a propagation delay of 10 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It functions in a non-inverting polarity and is housed in a 20-pin SOIC package.

Latches Feature Summary

• Provides eight transparent latches with three-state outputs for efficient bus organization
• Features edge-rate control circuitry to significantly improve noise characteristics
• Includes Ioff circuitry that supports partial-power-down mode operation
• Offers ESD protection exceeding JESD 22 standards for human-body and machine models

Latches Applications

• Bus-organized data storage systems
• Partial-power-down applications requiring output disabling
• TTL-to-CMOS interface circuits

Latches Procurement Notes

Verify the specific suffix 'TG4' against official manufacturer documentation to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision date to confirm the technical specifications align with your design requirements before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring octal data latching with high drive capability. The 64 mA low-level sink current makes it suitable for driving heavy loads on shared buses. Verify that the 5V operating voltage range meets the system power supply constraints. Consider the 10 ns propagation delay for timing analysis in synchronous digital designs.

Latches Part Context

This component belongs to the CY74FCT373T family of octal latches. It is functionally compatible with standard FCT and F logic devices. The device is part of Texas Instruments' broader portfolio of high-speed CMOS logic products designed for industrial and commercial temperature ranges.

Latches Replacement Considerations

The CY74FCT373T is a direct functional equivalent. Verify pinout compatibility and electrical parameters such as output current capabilities before substitution.
