SN74HCT244DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT244DW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the HCT logic series. It features a 20-SOIC surface-mount package with two independent four-bit sections. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides non-inverting data transfer from A inputs to Y outputs when the output enable (OE) signal is low, entering a high-impedance state when OE is high. Key electrical parameters include a maximum static current of 8 µA, a typical propagation delay of 13 ns, and output drive capabilities of ±6 mA at 5 V.
