74LVC16374ADL,118

Overview

The Nexperia 74LVC16374ADL,118 is a 16-bit D-type flip-flop with 3-state outputs, housed in a 48-pin SSOP package. It operates within a supply voltage range of 1.2 V to 3.6 V and supports data rates up to 200 MHz at 3.3 V. The device features low power consumption, overvoltage tolerant inputs up to 5.5 V, and bus-hold inputs to eliminate external pull-up resistors. It complies with JEDEC standards for various voltage levels and includes I_OFF circuitry for partial power-down mode operation.

Feature Summary

• Provides 16-bit data storage with independent output enable control for each byte.
• Features overvoltage tolerant inputs allowing direct interfacing with 5 V devices.
• Includes bus-hold functionality to maintain input states without external components.
• Supports partial power-down via I_OFF circuitry to prevent backflow current.

Applications

• High-speed data buffering in communication systems
• Register files in embedded processors
• Memory interface circuits requiring 3-state isolation

Procurement Notes

Verify the complete part number including the suffix ',118' which indicates the specific tape and reel packaging configuration. Confirm that the SSOP-48 package dimensions align with your PCB footprint requirements. Ensure design compatibility with the specified 1.2 V to 3.6 V operating range and check for any specific handling instructions related to the moisture sensitivity level defined in the datasheet.

Selection Notes

Select this component when a 16-bit parallel register with tri-state outputs is required in space-constrained designs. The SSOP-48 package offers a compact solution compared to larger QFP options. Consider the 200 MHz performance capability if high-speed data latching is critical. The overvoltage tolerance simplifies system design by removing level-shifting requirements for 5 V interfaces.

Part Context

This device belongs to the Nexperia 74LVC family of low-voltage CMOS logic ICs. It is functionally similar to other 16-bit latch variants but specifically implements positive-edge-triggered D-type flip-flops rather than transparent latches. The ADL suffix denotes the SSOP package variant, distinguishing it from TVSOP or TSSOP alternatives within the same logical family.

Replacement Considerations

Direct substitutes include the 74LVC16374ADGV (TVSOP-48) for pin-compatible board revisions requiring different package footprints. Cross-reference with industry-standard equivalents like the SN74LVC16374A for broader sourcing options, ensuring electrical parameters such as propagation delay and output drive strength remain compatible.
