74LVT16374MEA

Overview

The 74LVT16374MEA is a low-voltage 16-bit D flip-flop with 3-state outputs manufactured by onsemi (formerly Fairchild). It utilizes advanced BiCMOS technology for high-speed operation at 160 MHz while maintaining low power consumption. The device operates within a supply voltage range of 2.7 V to 3.6 V and features propagation delays as low as 4.5 ns at 3.3 V with 50 pF load capacitance. It provides strong drive capabilities with output currents of -32 mA (high) and +64 mA (low). Packaged in a 48-SSOP, it supports surface-mount installation across an operating temperature range of -40°C to +85°C.

Feature Summary

• Advanced BiCMOS technology enables high-speed performance comparable to 5V ABT logic while ensuring low power dissipation.
• Byte-controllable architecture allows independent control of two 8-bit sections via shared clock and output enable signals.
• Bus-holding data inputs eliminate the need for external pull-up resistors for unused input lines.
• Designed for hot-swapping applications with powered-up/high-impedance states preventing bus contention.

Applications

• High-speed parallel data storage in memory architectures
• Buffering and latching operations on system buses
• Clock distribution networks requiring precise timing alignment
• Interface circuits between low-voltage processors and 5V TTL peripherals

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package integrity and pin alignment against the 48-SSOP specification. Check for RoHS compliance documentation if environmental regulations apply. Ensure handling procedures meet ESD protection standards due to CMOS sensitivity. Review datasheet revisions for any updates regarding electrical characteristics or mechanical dimensions prior to integration.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data capture with byte-level control flexibility. It is suitable for applications needing robust drive strength and compatibility with both 3.3V logic families and 5V interfaces. Consider the 48-SSOP footprint for PCB layout constraints. Evaluate thermal management requirements given the operating temperature range. Compare against alternatives only if specific speed or current drive parameters differ significantly from these specifications.

Part Context

This part belongs to the 74LVT/74LVTH series of low-voltage logic devices. It is functionally compatible with the standard 7416374 family but optimized for lower voltage operation. The 'MEA' suffix denotes the specific SSOP-48 package variant. It represents a transition product from Fairchild Semiconductor to onsemi following corporate integration.

Replacement Considerations

Public confirmed substitute part numbers include SN74LVTH16374DGGR from Texas Instruments. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that the 74LVT16374MEA itself is marked as obsolete; ensure availability of replacement stock or qualified alternatives for production continuity.
