SN74HCT244APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT244APW is an octal buffer and line driver manufactured by Texas Instruments, utilizing HCT CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features non-inverting tri-state outputs. The device is organized into two independent 4-bit buffers with separate output enable inputs. It provides ±6 mA output drive capability at 5 V and exhibits low static current consumption of 8 µA. The component is housed in a TSSOP-20 surface-mount package and supports operation across an industrial temperature range from -40 °C to +85 °C.
