74LVC16374ABX,518

Overview

The Nexperia 74LVC16374ABX,518 is a 16-bit D-type transparent latch with 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device supports partial power-down via I_OFF circuitry and includes bus-hold data inputs. It is specified for industrial temperatures from -40 °C to +85 °C or +125 °C.

Feature Summary

• Provides 16-bit transparent latching with independent 3-state output control
• Features overvoltage tolerant inputs compatible with 5 V logic systems
• Includes bus-hold functionality to eliminate external pull-up resistors

Applications

• Data bus buffering in mixed voltage environments
• Parallel-to-serial conversion interfaces
• Memory address latching in embedded systems

Procurement Notes

Verify the specific suffix '518' against official Nexperia documentation to confirm the exact tape and reel packaging configuration. Ensure the selected temperature grade matches the application requirements, as specifications vary between -40 °C to +85 °C and -40 °C to +125 °C variants.

Selection Notes

Select this component when a high-density 16-bit latch with 3-state outputs is required. It is suitable for designs needing direct interface with TTL levels and operation in mixed 3.3 V and 5 V environments without additional level shifting components.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. It functions as a parallel-in/parallel-out storage element, commonly used in digital systems for temporary data retention and signal isolation on shared buses.

FAQ

Does the 74LVC16374ABX support partial power-down?

Yes, the device includes I_OFF circuitry that disables the outputs to prevent damaging backflow current when the device is powered down.

What is the input tolerance voltage?

The inputs are overvoltage tolerant up to 5.5 V, allowing safe interfacing with 5 V logic devices while operating at lower supply voltages.
