74ALVCH16825DGGS

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ALVCH16825DGGS is an 18-bit non-inverting buffer/driver with 3-state outputs, housed in a 56-lead TSSOP package. It comprises two independent 9-bit sections, each controlled by dual active-LOW output enable inputs (1OE1/1OE2 and 2OE1/2OE2). The device operates within a supply voltage range of 1.2 V to 3.6 V, supporting JEDEC standards for 1.65 V, 2.5 V, and 3.3 V logic families. It features bus hold circuitry on data inputs to maintain valid logic levels without external resistors. Static characteristics include input leakage currents up to 5 μA and output drive capabilities of ±24 mA at 3.0 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual 9-bit sections with separate active-LOW output enables for flexible bus-oriented control
• Active bus hold circuitry eliminates the need for external pull-up or pull-down resistors on unused inputs
• Low inductance multiple power and ground pins minimize noise and ground bounce effects
• Direct interface capability with TTL logic levels

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented applications requiring high-speed data buffering
• Systems utilizing MULTIBYTE flow-through standard pin-out architectures
• Interfaces driving 50 Ω transmission lines

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGGS' against current Nexperia documentation to confirm the exact tape-and-reel packaging configuration and marking details. Ensure the procurement source provides the official product data sheet revision history to validate compliance with the latest JEDEC ESD specifications and static characteristic limits. Confirm that the component status remains in production rather than obsolete or recommended for new designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 18-bit parallel data transfer with independent section control. The dual output enable structure allows precise management of bus states across two distinct 9-bit groups. Consider the wide supply voltage compatibility for mixed-voltage environments and the low power dissipation characteristics suitable for battery-operated or thermally constrained applications.

Buffers, Drivers, Receivers, Transceivers Part Context
