MC74LCX16373DT

Latches Overview

The MC74LCX16373DT is a low-voltage CMOS 16-bit transparent latch with 5 V-tolerant inputs and outputs. It operates from a 1.65 V to 5.5 V supply and features byte control via separate Output Enable (OE) and Latch Enable (LE) inputs for each byte. The device includes 16 D-type latches with 3-state non-inverting outputs. Key electrical parameters include a maximum propagation delay of 5.4 ns at 3.0 V to 3.6 V, balanced output sink and source capability of 24 mA at VCC = 3 V, and near-zero static supply current.

Latches Feature Summary

• Provides 5.0 V tolerant interface capability with standard TTL logic levels
• Supports live insertion and withdrawal operations
• Guarantees high impedance state when power supply is removed
• Features byte-controlled architecture allowing independent operation of two 8-bit sections

Latches Applications

• High-performance bus-oriented memory mapping
• Clock buffering and driving
• Cache memory systems

Latches Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping configuration. The DT suffix indicates a TSSOP-48 package. Confirm RoHS compliance status and check for automotive-grade variants if AEC-Q100 qualification is required for the target application environment.

Latches Selection Notes

Select this component for applications requiring 16-bit data storage with 5 V tolerance in low-voltage environments. Ensure the operating voltage range matches the system supply. Consider the 3-state output capability for bus sharing requirements and verify that the propagation delay specifications meet the timing constraints of the destination circuitry.

Latches Part Context

This device belongs to the 74LCX series of low-voltage CMOS logic integrated circuits manufactured by onsemi. The LCX family is designed for high-speed operation with low power consumption, bridging the gap between older LVC and newer LV technologies while maintaining compatibility with 5 V systems through specific input/output tolerances.

Latches Replacement Considerations

Check for MC74LCX16373DTR2G which shares the same functional specifications but utilizes tape and reel packaging instead of rail packaging. Verify pinout compatibility before substitution.
