MM74HC373MTCX

Latches Overview

The MM74HC373MTCX is a 3-STATE Octal D-Type Latch manufactured by onsemi, utilizing advanced silicon-gate CMOS technology. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55°C to +125°C. The device features a typical propagation delay of 18 ns at 5 V with a 45 pF load. It provides high noise immunity and can drive up to 15 LS-TTL loads. The component is housed in a TSSOP-20 package and is lead-free.

Latches Feature Summary

• High-speed octal D-type latching functionality using silicon-gate CMOS technology
• Three-state output capability for bus line interfacing
• Wide operating voltage range supporting 2 V to 6 V
• Internal input clamps protect against static discharge damage

Latches Applications

• Interfacing with bus lines in bus-organized systems
• Data storage applications requiring latch enable control
• Systems requiring high noise immunity and low power consumption

Latches Procurement Notes

Verify the specific ordering suffix 'X' corresponds to the tape and reel packaging configuration as defined in the official datasheet. Confirm that the TSSOP-20 WB package variant matches the required mechanical footprint for the target PCB design. Ensure compliance with RoHS and halide-free requirements specified for this part number.

Latches Selection Notes

Select this component when designing systems that require octal data latching with three-state outputs. It is suitable for applications needing compatibility with standard 74LS logic families while offering improved speed and lower power consumption. Consider the wide voltage range and temperature specifications for environmental adaptability.

Latches Part Context

This device belongs to the MM74HC373 series of high-speed octal D-type latches. It is functionally and pin-out compatible with the standard 74LS logic family. The product utilizes advanced silicon-gate CMOS technology to achieve high noise immunity and low quiescent current, making it distinct from older bipolar logic technologies.

Latches Replacement Considerations

Direct functional equivalents include the MM74HC373WM (SOIC-20) and MM74HC373MTC (TSSOP-20 tube). Verify package dimensions and shipping quantities when substituting between tube and tape-and-reel variants.
