SN74ALVCH16825DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16825 is an 18-bit buffer and line driver with 3-state outputs, designed for 1.65-V to 3.6-V VCC operation. It features active bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors. The device provides true data output and can be configured as two 9-bit buffers or one 18-bit buffer. It utilizes Texas Instruments' EPIC submicron process and includes ESD protection exceeding 2000 V per MIL-STD-883. Characterized for operation from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

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

What is the function of the OE inputs?

The 3-state control gate consists of a 2-input AND gate with active-low inputs. If either OE1 or OE2 is high, all nine affected outputs enter the high-impedance state.
