74VHCT373AMX

Latches Overview

The Fairchild Semiconductor 74VHCT373AMX is an octal transparent latch featuring three-state outputs, designed for high-speed bus-oriented operations. It operates with a supply voltage range of 2.0V to 3.6V and accepts TTL-compatible inputs, ensuring compatibility with standard logic families. The device utilizes advanced CMOS technology to achieve low power consumption while maintaining high-speed performance. Key electrical characteristics include propagation delays typical of 10ns at 5V and output drive capabilities suitable for driving multiple loads. The AMX suffix indicates tape and reel packaging.

Latches Feature Summary

• Octal configuration providing eight independent latching channels within a single package
• Three-state outputs enabling direct connection to system buses without additional buffering
• TTL-compatible input thresholds allowing seamless integration with legacy logic systems
• Advanced CMOS construction delivering reduced power dissipation compared to older technologies

Latches Applications

• Bus-oriented memory mapping in embedded systems
• Portable equipment requiring low voltage operation
• Clock delay circuits for timing synchronization
• Data register applications in communication interfaces

Latches Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure that the voltage requirements align with the target system design, as the device operates strictly within the 2.0V to 3.6V range. Confirm lead times and availability through authorized distributors, as supply chain fluctuations may impact delivery schedules for this component.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state bus isolation under low voltage conditions. The TTL-compatible inputs make it suitable for interfacing with 5V logic sources despite the lower operating voltage. Consider the propagation delay specifications if precise timing constraints exist in the application. Evaluate power consumption benefits relative to alternative logic families for battery-operated devices.

Latches Part Context

This part belongs to the 74VHCT series of high-speed CMOS logic devices. The VHCT series is characterized by its ability to interface directly with TTL logic levels while offering CMOS performance benefits. The 373 designation specifically refers to an octal D-type latch with three-state outputs, a common building block for data storage and transfer in digital circuits.

Latches Replacement Considerations

Equivalent parts from other manufacturers such as ON Semiconductor or NXP may offer compatible functionality. Verify pinout compatibility and electrical parameters before substitution. Check for any differences in recommended operating conditions or thermal characteristics that might affect performance in the existing design.
