SN74ALVCH16827DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16827DGGR is a 20-bit noninverting buffer and driver with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes the EPIC submicron CMOS process. The device architecture consists of two independent 10-bit sections, each equipped with separate output-enable signals (OE1 and OE2). Outputs become active only when both enable inputs for their respective section are low; otherwise, they enter a high-impedance state. The component is characterized for operation across an ambient temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Clock distribution and buffering
• Driving capacitive loads in portable systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGGR' corresponds to the TSSOP-56 package and tape-and-reel quantity of 2000 units. Confirm that the RoHS status and lead finish match project requirements. Ensure the moisture sensitivity level rating aligns with the assembly floor life constraints. Cross-reference the manufacturer part number against current availability lists to confirm production status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 1.65-V and 3.6-V logic domains requiring 20-bit widebus capabilities. The dual 10-bit section structure allows flexible partitioning of data paths. Verify that the required propagation delay and drive strength meet system timing specifications at the target operating voltage. Consider the thermal impedance characteristics if multiple devices operate in close proximity.
