74LVT16244MTDX

Overview

The Fairchild Semiconductor 74LVT16244MTDX is a low-voltage CMOS 16-bit buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.7V to 3.6V. The device provides high-speed performance with propagation delays typically around 5ns at 3.3V. It supports TTL-compatible inputs, allowing direct interfacing with 5V logic systems while operating at lower voltages. The component is housed in a 48-lead Thin Shrink Small Outline Package (TSSOP) with a pitch of 0.5mm.

Feature Summary

• Provides sixteen non-inverting buffers with independent three-state control for each nibble.
• Features 5V tolerant inputs and outputs, enabling safe operation in mixed-voltage environments.
• Designed for low power consumption with high noise immunity typical of CMOS technology.
• Supports live insertion and withdrawal without causing system damage due to high impedance states.

Applications

• Memory address and data bus drivers in portable electronic devices.
• Clock distribution networks requiring low skew and high drive capability.
• Bus-oriented transmitter and receiver circuits in communication systems.
• Interface bridging between 3.3V logic cores and 5V peripheral components.

Procurement Notes

Verify the specific suffix 'MTDX' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required by your assembly process. Cross-reference the ordering code with official distributor catalogs to confirm availability status and lead times, as lifecycle changes may affect production. Validate that the intended application voltage falls strictly within the 2.7V to 3.6V operational range.

Selection Notes

Select this component when designing systems that require driving long buses or multiple loads from a single source. It is suitable for applications needing isolation between input and output signals. Consider the TSSOP package constraints regarding thermal dissipation and board space. Compare propagation delay specifications against system timing requirements to ensure signal integrity is maintained across the 16-bit width.

Part Context

This part belongs to the 74LVT logic family, which is optimized for low-voltage digital applications. It serves as a standard interface solution in consumer electronics and industrial control systems where voltage translation and signal buffering are critical. The 16-bit configuration reduces component count compared to using eight separate 8-bit drivers, simplifying PCB layout and design complexity.

Replacement Considerations

Check for equivalents such as the 74LCX16244 series for lower voltage operations or the 74LVTH16244 for enhanced speed. Verify pinout compatibility before substitution. Ensure that any replacement part maintains the same three-state functionality and voltage tolerance levels to prevent circuit malfunction.
