MC74HCT373ADTR2G

Latches Overview

The MC74HCT373ADTR2G is an octal transparent latch manufactured by onsemi, belonging to the 74HCT logic family. It features eight D-type latches with three-state outputs in a non-inverting configuration. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 20-TSSOP package (0.173 inch, 4.40 mm wide). It exhibits a maximum propagation delay of 31 ns at 5 V with 50 pF load, low static current of 4 µA, and output drive capabilities of 6 mA for both high and low states. The component functions reliably across an operating temperature range of -55°C to +125°C.

Latches Feature Summary

• Octal transparent latch architecture with three-state outputs
• CMOS technology compatible with TTL input levels
• Wide operating temperature range for industrial applications

Latches Applications

• Parallel data storage in digital systems
• Bus-oriented memory mapping
• I/O port expansion for microcontrollers

Latches Procurement Notes

Verify the specific suffix ADTR2G confirms the TSSOP-20 package and reel packaging format. Confirm RoHS compliance status and manufacturing origin through official datasheets or supplier declarations. Ensure the ordering part number matches the required logic family and pinout specifications for your design.

Latches Selection Notes

Select this component when interfacing CMOS devices with TTL-compatible logic levels is required. The HCT series ensures compatibility with standard 5 V logic families while maintaining CMOS power efficiency. Verify that the 20-TSSOP package dimensions fit the PCB footprint constraints and thermal requirements of the target application.

Latches Part Context

This part belongs to the MC74HCT373A series of octal latches produced by onsemi. It is designed for high-density digital applications requiring parallel-to-serial conversion or data buffering. The device integrates eight independent latches with common clock and output enable controls, providing a compact solution for complex digital circuitry.

Latches Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers within the 74HCT373 specification. Verify electrical parameters such as propagation delay and output current against the original requirements before substitution.
