74LVTH16835MEAX

Universal Bus Functions Overview

The onsemi 74LVTH16835MEAX is an 18-bit universal bus driver featuring D-type latches and flip-flops for transparent, latched, and clocked data modes. It operates at a supply voltage of 2.7V to 3.6V with inputs compatible up to 5.5V. The device provides 3-STATE outputs capable of sourcing -32 mA and sinking 64 mA. Propagation delays range from 1.2 ns to 6.1 ns depending on the control path. It utilizes BiCMOS technology for high-speed operation and low power dissipation.

Universal Bus Functions Feature Summary

• Combines D-type latches and flip-flops to support transparent, latched, and clocked data flow modes via OE, LE, and CLK controls.
• Bushold data inputs eliminate the need for external pull-up resistors to maintain unused input states.
• Provides glitch-free bus loading during power up/down transitions through automatic high impedance output states.
• Supports live insertion and extraction while maintaining interface capability between 3.3V and 5V systems.

Universal Bus Functions Applications

• High-density data buffering in 3.3V memory architectures
• Clock distribution networks requiring precise timing control
• Bus interfaces bridging 3.3V logic to 5V tolerant environments

Universal Bus Functions Procurement Notes

Verify the specific package variant against the datasheet ordering codes. The MEAX suffix indicates a tape and reel configuration of the MS56A SSOP package. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure input voltage levels do not exceed the absolute maximum ratings to prevent damage.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide bus interface is required with integrated storage capabilities. The bushold feature simplifies design by removing external pull-up components for floating inputs. Consider the propagation delay specifications relative to system clock speeds. Verify that the 56-lead SSOP package fits the available PCB footprint constraints.

Universal Bus Functions Part Context

This device belongs to the LVTH series of low-voltage bus drivers manufactured originally by Fairchild Semiconductor and now distributed by onsemi. The series focuses on providing high-speed performance similar to 5V ABT devices while maintaining lower power consumption suitable for modern 3.3V applications.

Universal Bus Functions Replacement Considerations

Check for direct pin-compatible equivalents within the same LVTH family or other manufacturers offering 18-bit bus drivers with identical latch functionality and bushold features. Verify that replacement parts meet the same electrical characteristics and package dimensions.
