SN74ALVTH16601DLR

Overview

The SN74ALVTH16601DLR is an 18-bit universal bus transceiver utilizing Advanced BiCMOS technology. It supports 2.5-V and 3.3-V VCC operation with TTL interface capability for 5-V systems. The device integrates D-type latches and flip-flops, enabling transparent, latched, clocked, or clock-enabled data flow modes. It features 3-state outputs, high-drive current capabilities of -32/64 mA at 3.3 V, and active bus-hold circuitry. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Combines D-type latches and flip-flops for flexible data flow control in transparent, latched, clocked, or clock-enabled modes.
• Supports mixed-mode signal operation allowing 5-V input and output voltages with 2.3-V to 3.6-V VCC.
• Includes Ioff and power-up 3-state support to prevent damaging backflow during hot insertion.
• Features active bus-hold circuitry to maintain valid logic levels on unused or floating data inputs.

Applications

• High-density memory buffering
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify the specific ordering suffix 'DLR' corresponds to the SSOP-56 package configuration required for your design. Confirm that the obsolete status does not impact long-term supply requirements. Ensure all unused control inputs are tied to VCC or GND to guarantee proper device operation as specified in the datasheet recommendations.

Selection Notes

Select this component when an 18-bit wide bus interface is required with mixed-voltage compatibility between 2.5-V/3.3-V logic and 5-V systems. The ALVTH series provides high drive strength suitable for driving multiple loads. Consider the SSOP-56 package dimensions and thermal characteristics relative to available PCB space and heat dissipation needs.
