74LVT16245MEAX

Overview

The onsemi 74LVT16245MEAX is a low-voltage 16-bit bidirectional transceiver with 3-STATE outputs, designed for bus-oriented applications. It operates at VCC voltages between 2.7V and 3.6V and features TTL-compatible inputs capable of interfacing with 5V systems. The device utilizes advanced BiCMOS technology to achieve high-speed operation while maintaining low power dissipation. Packaged in a 48-lead Small Shrink Outline Package (SSOP), it supports byte-controlled or full 16-bit data flow direction determined by T/R inputs.

Feature Summary

• Provides non-inverting bidirectional buffering with 3-STATE outputs for bus-oriented applications
• Features input interface capability to 5V systems despite low-voltage operation
• Supports live insertion and extraction via power-up/down high impedance states
• Offers byte-controlled functionality allowing independent control of two 8-bit bytes

Applications

• Bus-oriented memory and disk controller applications
• High-density data acquisition systems
• Communications systems requiring level translation
• Portable equipment utilizing 3.3V logic environments

Procurement Notes

Verify the specific ordering code suffix 'X' confirms the tape and reel packaging configuration as documented in the datasheet notes. Ensure compatibility with the MS48A package dimensions and JEDEC MO-118 standards. Confirm that the component meets the required operating temperature range of -40°C to +85°C for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a 16-bit bidirectional buffer with 3-STATE outputs is required for 3.3V systems interfacing with 5V logic. Consider the 74LVTH16245 variant if bushold inputs are needed to eliminate external pull-up resistors. Evaluate the SSOP package constraints against PCB space requirements and ensure the drive current capabilities meet the load requirements of the destination bus lines.

Part Context

This component belongs to the LVT logic family, characterized by low voltage operation and BiCMOS fabrication. It is functionally compatible with the standard 74 series 16245 devices but optimized for lower power consumption. The MEAX designation specifically identifies the 48-lead SSOP package variant manufactured under Fairchild Semiconductor specifications, now part of the onsemi portfolio.

Replacement Considerations

The 74LVTH16245MEA serves as a functional substitute within the same package offering bushold inputs. Other manufacturers producing equivalent 16-bit transceivers must be evaluated for pinout compatibility and electrical parameter alignment.
