CY74FCT2373ATQCTE4

Latches Overview

The CY74FCT2373ATQCTE4 is an octal transparent latch manufactured by Texas Instruments, belonging to the FCT logic series. It features eight D-type latches with TTL-compatible inputs and three-state outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum propagation delay of 6.0 ns at 5 V. It provides high drive capability with output currents of 32 mA for both sourcing and sinking. The component is housed in a 20-pin SSOP package and is rated for operation between -40°C and +85°C.

Latches Feature Summary

• Provides eight independent transparent latches with TTL-compatible input thresholds
• Features three-state outputs controlled by an output enable pin
• Delivers high drive strength suitable for bus-oriented architectures

Latches Applications

• Bus-oriented memory mapping
• Clocking data registers
• I/O port expansion

Latches Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS status against the manufacturer's current documentation. Confirm the package type matches the required PCB footprint. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent damage.

Latches Selection Notes

Select this component when an octal latch with three-state outputs and TTL-compatible inputs is required. It is suitable for designs needing high drive current and fast switching speeds within a 5V logic environment. Consider the SSOP package constraints for board space.

Latches Part Context

This part belongs to the Texas Instruments FCT (Fast CMOS) family, designed for high-speed digital applications. It serves as a registered transceiver or latch variant within the broader 74FCT series, offering performance comparable to LS-TTL but with CMOS power consumption characteristics.
