SN74LVT16501DLR

Overview

The SN74LVT16501DLR is an 18-bit universal bus transceiver utilizing Advanced BiCMOS (ABT) technology for 3.3-V operation. It supports mixed-mode signal environments with 5-V tolerant inputs and outputs. The device features a flow-through architecture, distributed VCC/GND pins to minimize switching noise, and active bus-hold circuitry on data inputs. It operates within a supply voltage range of 2.7 V to 3.6 V and supports clock frequencies up to 150 MHz at 3.3 V. The component is housed in a 56-pin Thin Shrink Small-Outline (DGG) package.

Feature Summary

• Combines D-type latches and flip-flops for transparent, latched, or clocked data modes
• Supports live insertion and unregulated battery operation down to 2.7 V
• Active bus-hold circuitry eliminates the need for external pullup/pulldown resistors

Applications

• Mixed-mode signal processing between 5-V and 3.3-V systems
• High-speed data bus interfaces requiring low static power dissipation
• Applications necessitating live insertion capabilities without system disruption

Procurement Notes

Verify that the specific ordering suffix DLR corresponds to the TSSOP (DGG) package variant. Confirm the manufacturer's current production status and lifecycle stage prior to procurement. Ensure compatibility with the required operating temperature range of -40°C to 85°C for commercial applications.

Selection Notes

Select this component when designing 3.3-V systems requiring 18-bit bidirectional data transfer with mixed-voltage tolerance. The ABT technology offers lower power consumption compared to standard CMOS alternatives. Consider the flow-through pinout for optimized PCB layout routing and reduced trace lengths.

Part Context

This device belongs to Texas Instruments' Widebus family of universal bus transceivers. It is part of the SN74LVT series, designed specifically for low-voltage digital logic applications. The 'DLR' suffix indicates the specific tape-and-reel packaging configuration for the 56-pin thin shrink small-outline package.

Replacement Considerations

Public confirmed substitute part numbers include SN74LVTH16501DGGR, SN74LVTH16501DL, and SN74LVTH16501DLR from Texas Instruments.
