74ALVCH16646DGG512

Buffers, Drivers, Receivers, Transceivers Overview

The 74ALVCH16646DGG512 is a 16-bit bus transceiver and register with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 2.3 V to 3.6 V and supports data transmission between two buses (A and B). The device includes D-type flip-flops for storing data, controlled by output enable (nOE), direction (nDIR), and clock inputs (nCPAB/nCPBA). It features active bus-hold circuitry on all data inputs and complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C/JESD36.

• Direct interface compatibility with TTL logic levels

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed multiplexed data transmission systems
• Memory buffer applications requiring registered storage
• Bus isolation circuits with selectable data sources

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '512' against official Nexperia documentation to confirm tube packaging requirements. Confirm that the TSSOP56 package variant matches the required board layout dimensions. Ensure design compliance with the specified -40 °C to +85 °C operating temperature range before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width with internal registration is required for bus interfacing. The ALVCH series provides low power consumption suitable for CMOS applications. Verify that the 2.3 V to 3.6 V supply voltage range aligns with the system's power architecture and that the TSSOP56 package fits the available footprint constraints.

Buffers, Drivers, Receivers, Transceivers Part Context
