74LVT162245MEAX

Overview

The Fairchild Semiconductor 74LVT162245MEAX is a low-voltage 16-bit bidirectional bus transceiver featuring three-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and supports LVTTL input and output levels. The device incorporates byte control for flexible data routing and includes bushold inputs to maintain stable states on unused lines without external pull-up resistors. Designed for high-speed applications, it offers a propagation delay of 4.6 ns with an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides sixteen noninverting bidirectional buffers with three-state outputs for efficient bus-oriented data transfer.
• Features bushold data inputs that eliminate the need for external pull-up resistors to hold unused inputs in a defined state.
• Supports live insertion and extraction by ensuring power-up/down high impedance to prevent glitch-free bus loading.

Applications

• Bus-oriented memory and I/O mapping systems
• Clock drivers and buffer circuits
• Bidirectional data bus architectures

Procurement Notes

Verify the specific suffix 'MEA' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the component matches the required logic family specifications for your target application. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer at low voltages. The bushold feature simplifies design by removing external pull-up requirements. Verify that the 3.3V operating range aligns with the system's power supply and that the SSOP-48 package fits the PCB layout constraints.

Part Context

This device belongs to the 74LVT logic family, designed for low-voltage digital applications. It serves as a direct functional replacement for older 5V 74FCT or 74ACT series transceivers in modern low-power designs. The 16-bit configuration allows for wide data path handling in compact packages.

Replacement Considerations

Check for pin-compatible alternatives such as the SN74LVT162245 from Texas Instruments. Verify that substitute parts maintain the same 2.7V to 3.6V operating voltage and 16-bit bidirectional functionality. Confirm package compatibility if replacing in existing hardware layouts.
