SN74AHCT244PWR-P

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHCT244PWR is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes CMOS technology. The device contains eight non-inverting channels organized into two groups of four, each with a separate output enable input. It is housed in a 20-pin TSSOP package designed for surface-mount applications. The component supports propagation delays as low as 7.5 ns at 3.3 V and functions reliably across an operating temperature range of -40°C to +85°C.
