M74HC244TTR

Buffers, Drivers, Receivers, Transceivers Overview

The M74HC244TTR is an octal bus buffer with 3-state outputs, fabricated using advanced high-speed silicon gate C2MOS technology. It features non-inverted logic controlled by two G inputs that govern four bus buffers each. The device operates within a wide voltage range of 2V to 6V and includes protection circuits against static discharge and transient excess voltage on all inputs. Designed for memory address drivers and similar applications, it offers balanced propagation delays and symmetrical output impedance.
