The DM74AS244N is a 3-STATE bus driver designed for bidirectional or unidirectional buffering in memory, microprocessor, and communication systems. It features eight buffers organized with four buffers sharing a common 3-STATE enable gate, allowing for flexible configurations. The device operates with a supply voltage range of 4.5V to 5.5V and is specified for a temperature range of 0¬8C to +70¬8C. The output characteristics include low impedance suitable for driving terminated transmission lines down to 133Oc, while the high input impedance minimizes loading on the transmission line. The DM74AS244N is compatible with CMOS interfaces and offers improved switching performance with lower power dissipation compared to traditional Schottky TTL devices. It is available in a 20-lead plastic dual-in-line package (PDIP) and is functional and pin compatible with 74LS and Schottky counterparts. Engineers may consider this product for applications requiring efficient signal buffering with minimal power loss and high-speed performance.
