74LVT16240MTD

Overview

The onsemi 74LVT16240MTD is a low-voltage 16-bit inverting buffer and line driver featuring 3-STATE outputs. It operates within a supply voltage range of 2.7V to 3.6V, with inputs tolerant up to 5.5V for TTL interface compatibility. The device utilizes advanced BiCMOS technology to achieve high-speed operation while maintaining low power dissipation. Key electrical parameters include propagation delays ranging from 1.0ns to 4.2ns depending on voltage conditions, output currents of ±32mA at HIGH state and 64mA at LOW state, and an operating temperature range of -40°C to +85°C. It is housed in a 48-Lead Thin Shrink Small Outline Package (TSSOP).

Feature Summary

• Provides 16-bit inverting buffering with independent nibble control via four Output Enable inputs.
• Supports live insertion and extraction through power-up/down high impedance functionality.
• Features 3-STATE outputs that ensure glitch-free bus loading during power transitions.
• Compatible with 5V systems despite low-voltage operation.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Procurement Notes

Verify the specific ordering code suffix against current manufacturer documentation to confirm package type and reel configuration. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Ensure the component meets the required operating temperature range for the target environment. Cross-reference the datasheet revision date to validate all electrical characteristics and absolute maximum ratings.

Selection Notes

Select this component when designing systems requiring 16-bit data buffering with active-low enable control. It is suitable for applications needing interface between 3.3V logic and 5V environments. Consider the TSSOP-48 package constraints regarding PCB space and thermal management. Evaluate the propagation delay specifications against system timing requirements to ensure signal integrity.

Part Context

This part belongs to the LVT logic family, designed for low-voltage digital applications. It functions as a standard buffer/driver within the broader category of logic integrated circuits. The device is functionally compatible with the 74 series 16240 but optimized for lower voltage operation. It represents a transition component for systems migrating from 5V to 3.3V logic standards.

Replacement Considerations

The 74LVTH16240MTD is a functional variant within the same family, distinguished by bushold data inputs which eliminate the need for external pull-up resistors. Verify if bushold capability is required for the specific application design before substituting.
