74LVT16244MEA

Overview

The Fairchild Semiconductor 74LVT16244MEA is a 16-bit non-inverting buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V. The device provides high-level output current of -32 mA and low-level output current of 64 mA, with a maximum propagation delay of 4.6 ns. It utilizes BiCMOS logic technology and accepts LVTTL input levels while producing LVTTL output levels. The component is housed in an SSOP-48 package and supports surface mount installation. It functions as two independent circuits with a non-inverting polarity and is rated for operation between -40°C and +85°C.

Feature Summary

• Provides sixteen non-inverting buffers with three-state outputs for memory, address, or clock driving applications.
• Supports live insertion and withdrawal through power-down high impedance inputs and outputs.
• Utilizes patented noise and EMI reduction circuitry for signal integrity.

Applications

• Memory and address drivers
• Clock drivers
• Bus oriented transmitter/receiver

Procurement Notes

Verify the specific manufacturer designation, as Fairchild Semiconductor has undergone corporate restructuring and brand transitions. Confirm that the part number corresponds to the original Fairchild specifications rather than subsequent iterations from ON Semiconductor or other entities. Ensure the SSOP-48 package type matches the design requirements. Cross-reference the RoHS compliance status and lead-free finishing details against the specific production batch documentation to ensure compatibility with assembly processes.

Selection Notes

Select this component when a 16-bit wide interface with 3-state control is required for 3.3V systems. The LVTTL compatibility ensures interoperability with standard logic families. The SSOP-48 package offers a compact solution for dense PCB layouts. Consider the 4.6 ns propagation delay for timing constraints. Verify that the 64 mA low-level sink capability meets the load requirements of the destination devices without exceeding thermal limits.

Part Context

This device belongs to the 74LVT logic family, designed for low-voltage digital applications. It serves as a unidirectional buffer, distinct from bidirectional transceivers like the 74LVTH162245. The 16-bit width allows for parallel data handling, making it suitable for wide bus architectures. The 3-state feature enables multiple drivers to share a common bus line efficiently.

Replacement Considerations

The Nexperia 74LVT16244BEV/G,55 is a documented alternative within the same logic family. Verify pinout compatibility and electrical parameter alignment before substitution. Note that the Nexperia part may have different packaging or ordering suffixes requiring physical verification.
