74AVC9112DCH

Overview

The Nexperia 74AVC9112DCH is a 1-to-4 fan-out buffer designed for clock distribution applications. It features a single data input (A), four non-inverting outputs (Yn), and an active LOW output enable input (OE). The device operates within a supply voltage range of 0.8 V to 3.6 V. Key electrical parameters include a maximum propagation delay of 15.7 ns at 1.2 V, with typical values ranging from 0.4 ns to 31 ns depending on voltage. It supports data rates up to 380 Mbit/s at 3.3 V and includes Schmitt trigger inputs for noise tolerance.

Feature Summary

• 1-to-4 fan-out buffer with Schmitt trigger inputs for slow rise/fall time tolerance
• Wide supply voltage range: 0.8 V to 3.6 V; inputs accept voltages up to 3.6 V
• High-speed performance: 380 Mbit/s at 3.3 V, 200 Mbit/s at 1.8 V/2.5 V
• IOFF circuitry prevents backflow current during power-down states

Applications

• Clock distribution networks
• Voltage translation between logic domains
• Signal buffering in low-voltage systems

Procurement Notes

Verify the ordering suffix 'DCH' corresponds to the VSSOP8 package (SOT765-1) and -40 °C to +125 °C temperature range. Confirm RoHS compliance and REACH status via the manufacturer's latest documentation before procurement.

Selection Notes

Select this component when a single-ended 1-to-4 fan-out buffer is required for clock signals. Ensure the operating voltage falls within the 0.8 V to 3.6 V range. Consider the VSSOP8 package dimensions if board space is constrained compared to the XSON8 alternative.

Part Context

The 74AVC9112DCH belongs to the Nexperia 74AVC series of advanced low-voltage CMOS logic devices. It is functionally identical to the 74AVC9112GT but utilizes a different package format. The 'DCH' suffix specifically denotes the VSSOP8 plastic very thin shrink small outline package.

Replacement Considerations

The 74AVC9112GT serves as a direct functional replacement using the XSON8 package. Verify pinout compatibility and thermal dissipation requirements when substituting packages.
