SN74ALVCH16827DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16827DLR is a 20-bit noninverting buffer/driver with 3-state outputs, designed for 1.65-V to 3.6-V VCC operation. It consists of two independent 10-bit sections, each featuring separate output-enable signals (OE1 and OE2). The device utilizes an EPIC submicron process and includes active bus-hold circuitry on data inputs to maintain valid logic levels without external pullup or pulldown resistors. It operates within a temperature range of -40°C to 85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Composed of two independent 10-bit buffer sections with separate dual output-enable control signals
• Features active bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors
• Provides ESD protection exceeding 2000 V per MIL-STD-883 Method 3015

Buffers, Drivers, Receivers, Transceivers Applications

• High-density data buffering in widebus architectures
• Driving multiple loads across parallel buses
• Interface isolation between different voltage domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DLR' corresponds to the tape-and-reel packaging format rather than tube packaging. Confirm that the component status remains active for production use. Ensure compatibility with the required 56-pin SSOP footprint during PCB layout verification.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a high-channel-count buffer with independent section control is required. The dual OE inputs allow flexible enable logic configuration. Verify that the supply voltage range aligns with the system's 1.65-V to 3.6-V requirements and that the operating temperature meets environmental specifications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments Widebus family, utilizing Enhanced-Performance Implanted CMOS (EPIC) technology. It provides a cost-effective solution for applications requiring extensive bus driving capabilities within a compact 56-pin SSOP package, supporting both standard and low-voltage logic interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacement options include the SN74ALVCH16827DL variant, which offers identical electrical characteristics but utilizes tube packaging instead of tape-and-reel. Ensure pinout and functional compatibility remain unchanged when substituting packaging types.
