74LVT162245MEAX

Overview

The 74LVT162245MEAX is a 16-bit bus transceiver utilizing BiCMOS logic technology. It operates within a supply voltage range of 2.7 V to 3.6 V and features non-inverting, three-state outputs. The device supports LVTTL input levels and LVTTL output levels. It includes bushold data inputs to eliminate external pullup resistors for unused inputs. The A Port outputs provide equivalent series resistance of 25Ω, while the B Port outputs offer higher drive capability with source/sink currents of -32 mA/+64 mA.

Feature Summary

• Bushhold data inputs eliminate the need for external pullup resistors to hold unused inputs
• A Port outputs include equivalent series resistance making external termination resistors unnecessary
• Power Up/Down high impedance provides glitch-free bus loading
• Live insertion/extraction permitted

Applications

• Systems requiring interface capability at 5V VCC
• Bus transceiver applications in low-voltage digital circuits
• High-speed data transmission lines

Procurement Notes

Verify the specific suffix MEAX against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements of 2.7 V to 3.6 V. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference pinouts with ECAD models for accurate PCB layout integration.

Selection Notes

Select this component when 16-bit bidirectional data transfer is required between different voltage domains or buses. The bushhold feature simplifies design by removing external components for unused lines. The integrated series resistance on Port A reduces signal integrity issues without additional termination parts. Suitable for applications demanding live insertion capabilities and robust ESD protection.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage operation. It is functionally compatible with standard 74 series devices but optimized for lower power consumption and faster switching speeds. The MEAX designation typically indicates a specific packaging variant, such as SSOP-48, distributed by onsemi following its acquisition of Fairchild Semiconductor assets.

Replacement Considerations

The 74LVTH162245MEA is a functional alternative that shares similar characteristics but lacks the bushhold feature. Verify if the absence of bushhold inputs impacts the specific application design. Other 16-bit LVT bus transceivers from different manufacturers may require level shifting verification.
