SN74HCT244AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT244AN is an octal buffer and line driver manufactured by Texas Instruments, utilizing HCT CMOS technology. It features a 20-pin PDIP package and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides non-inverting data transfer with three-state outputs controlled by separate output enable inputs. Key electrical parameters include a maximum static current of 8 µA and a typical propagation delay of 13 ns at 5 V. It supports low input currents of 1 µA maximum and offers ±6 mA output drive capability.
