SN74ALVCH16827DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16827DL 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 process. The device comprises two independent 10-bit sections, each featuring separate output-enable inputs (OE1 and OE2). Both enable signals must be low for the corresponding Y outputs to become active; otherwise, the outputs enter a high-impedance state. Active bus-hold circuitry maintains unused or floating data inputs at valid logic levels without external resistors. The component is characterized for operation across an ambient temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features active bus-hold circuitry on data inputs to maintain valid logic levels for unused or floating lines, eliminating the need for external pullup or pulldown resistors.
• Composed of two independent 10-bit buffer sections, each controlled by dual output-enable inputs that require both signals to be low for active output states.
• Provides ESD protection exceeding 2000 V per MIL-STD-883 Method 3015 and latch-up performance exceeding 250 mA per JESD 17.

Buffers, Drivers, Receivers, Transceivers Applications

• High-density buffering and driving applications in portable systems
• Clock distribution and buffering in mobile communication devices
• Data bus drivers in battery-powered consumer electronics

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP-56 package configuration required for your design. Confirm current production status directly with Texas Instruments, as availability may vary. Ensure compliance with RoHS directives and check for any updated lifecycle notices prior to finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring 20-bit widebus buffering with independent section control. It is suitable for applications needing active bus-hold functionality to simplify input handling. Consider the SSOP-56 package constraints and verify that the 1.65-V to 3.6-V operating range aligns with your system's power supply architecture.
