SN74ALVCH16863DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16863 is an 18-bit noninverting bus transceiver designed for synchronous communication between data buses. It operates within a supply voltage range of 1.65 V to 3.6 V and supports bidirectional data transmission between the A and B buses based on control inputs. The device features active bus-hold circuitry to maintain valid logic levels on floating inputs, eliminating external pullup or pulldown resistors. It provides three-state outputs and includes ESD protection exceeding 2000 V per MIL-STD-883. Characterized for operation from -40°C to +85°C, it utilizes EPIC submicron CMOS technology.

Buffers, Drivers, Receivers, Transceivers Applications

• Synchronous communication between data buses
• Bus-oriented memory and signal switching
• Configurable as two 9-bit transceivers or one 18-bit transceiver

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against project requirements, as the component is available in TSSOP (DGG) configurations. Confirm that the selected ordering suffix aligns with the desired tape and reel quantity specifications. Ensure compatibility with the target operating temperature range of -40°C to +85°C during system design validation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring wide voltage operation between 1.65 V and 3.6 V. The integrated bus-hold feature simplifies board layout by removing the need for discrete pull-up or pull-down resistors on data lines. Consider the 56-pin TSSOP package dimensions when determining PCB footprint constraints and thermal management strategies for high-density designs.
