74FCT373PATPY

Latches Overview

The IDT 74FCT373PATPY is an octal transparent latch belonging to the FCT logic family, manufactured by Integrated Device Technology. It features eight D-type latches with three-state outputs and operates on a single supply voltage of 5V. The device utilizes advanced CMOS technology to provide high-speed performance while maintaining low power consumption. It is housed in a 20-pin SSOP package, designed for surface-mount applications requiring compact form factors. The component supports industrial temperature ranges and includes balanced output drivers to minimize system switching noise.

Latches Feature Summary

• Octal configuration providing eight independent transparent D-type latches within a single integrated circuit
• Three-state outputs allowing direct connection to bus structures without external pull-up or pull-down resistors
• Advanced CMOS construction ensuring high-speed operation combined with low power dissipation characteristics
• Balanced output drivers engineered to reduce system switching noise and ground bounce effects

Latches Applications

• Temporary data storage in digital processing systems
• Implementation of memory address latches for memory interfaces
• I/O port buffering in microcontroller-based designs
• Bus driver applications requiring tri-state control

Latches Procurement Notes

Verify the specific suffix PATPY against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm current production status as legacy components may face discontinuation. Ensure the SSOP-20 package dimensions match your PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate that the operating temperature range meets your system's thermal constraints.

Latches Selection Notes

Select this component when designing systems requiring octal latching with bus-compatible outputs. The FCT series offers a suitable replacement for older ABT functions with improved speed and lower power. Consider the SSOP-20 package size relative to available board space. Verify that the 5V supply voltage aligns with your system's logic levels. Evaluate the propagation delay specifications against your timing requirements for reliable data capture.

Latches Part Context

This part belongs to the 74FCT373T series of octal transparent latches from IDT. The FCT family represents Fast CMOS technology, bridging the gap between standard TTL and high-speed CMOS logic families. These devices are commonly used in computer peripherals and communication systems where moderate speed and low power are critical. The 74FCT373 variant specifically provides non-inverting latching functionality with tri-state control.

Latches Replacement Considerations

Cross-reference with other manufacturers' 74FCT373 equivalents such as those from Texas Instruments or Renesas. Verify pin-to-pin compatibility before substitution. Check if alternative packages like TSSOP or SOIC are available from different suppliers. Ensure that the replacement device meets the same electrical and mechanical specifications.
