74ALVCH16827DGGRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16827DGGRE4 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 comprises two independent 10-bit sections, each equipped with separate output-enable signals (OE1 and OE2). Both enable inputs must be low for the corresponding Y outputs to become active; otherwise, the outputs enter a high-impedance state. Active bus-hold circuitry is integrated on data inputs to maintain valid logic levels without external pullup or pulldown resistors.

Buffers, Drivers, Receivers, Transceivers FAQ

How are the output-enable signals configured?

Each 10-bit section has two output-enable inputs (OE1 and OE2). Both must be low for the outputs to be active. If either is high, the outputs enter a high-impedance state.

What is the purpose of the bus-hold circuitry?

Active bus-hold circuitry holds unused or floating data inputs at a valid logic level, eliminating the need for external pullup or pulldown resistors.
