74LVC162373ADL,112

Latches Overview

The Nexperia 74LVC162373ADL,112 is a 16-bit D-type transparent latch featuring 30 Ω series termination resistors and 5 V tolerant inputs/outputs with 3-state outputs. It operates on a supply voltage range of 1.2 V to 3.6 V. The device supports two 8-bit transparent latches or a single 16-bit latch configuration, controlled by two latch enables (1LE, 2LE) and two output enables (1OE, 2OE). Inputs accept voltages up to 5.5 V, allowing direct interface with TTL levels and mixed 3.3 V/5 V environments. Schmitt-trigger action ensures tolerance for slower input rise/fall times. IOFF circuitry prevents backflow current during partial power-down. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Operating temperature ranges from -40 °C to +125 °C.

Latches Feature Summary

• Integrated 30 Ω series termination resistors for signal integrity
• IOFF circuitry enables safe partial power-down mode operation
• Schmitt-trigger inputs provide noise immunity and tolerance for slow transitions
• 5 V tolerant I/O allows direct interfacing with 3.3 V and 5 V logic systems

Latches Applications

• Parallel data storage in high-speed digital systems
• Bus holding applications requiring stable data retention
• Mixed-voltage level translation between 3.3 V and 5 V domains
• Transparent latch configurations for temporary data buffering

Latches Procurement Notes

Verify the specific ordering suffix ',112' corresponds to the TSSOP48 package (SOT362-1) as defined in the official datasheet. Confirm that the required variant matches the LVC family specifications rather than the LVCH variant, which includes bus hold functionality not present in the standard LVC version. Ensure design compliance with the specified absolute maximum ratings and operating conditions prior to integration.

Latches Selection Notes

Select this component when 16-bit parallel latching with integrated termination is required. The LVC variant lacks the bus hold feature found in the LVCH counterpart; choose based on whether internal pull-up/pull-down stability is needed. Verify that the 30 Ω termination meets transmission line requirements. Ensure the application operates within the 1.2 V to 3.6 V supply range and utilizes the 5 V tolerant I/O capabilities for mixed-voltage compatibility.

Latches Part Context

This part belongs to the Nexperia 74LVC/LVCH162373A family of 16-bit D-type transparent latches. It shares functional architecture with variants differing primarily in package type and the presence of bus hold circuits (LVCH). The ADL suffix denotes the TSSOP48 plastic thin shrink small outline package. It is designed for low-power CMOS applications requiring high-speed data latching with robust ESD protection and overvoltage tolerance.

Latches Replacement Considerations

The 74LVCH162373ADL offers identical electrical characteristics but includes bus hold circuits on all data inputs. Direct substitution requires verifying if the additional bus hold functionality impacts the specific circuit design. Other packages such as TSSOP48 (DGG) are available within the same family.
