SN74ALVCH244PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH244PWR is an octal buffer and line driver from the Texas Instruments ALVCH logic family. It features eight non-inverting channels with three-state outputs, organized into two four-bit sections with independent output enable inputs. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical parameters include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delays are specified at 3.1 ns and 2.8 ns. It functions within a temperature range of -40°C to +85°C and utilizes a TSSOP-20 surface-mount package.
