Partnumber Manufacturer Quantity Availability
74VHCT244 FAIRCHILD 250 In Stock

Description and Introduction

Octal Buffer/Line Driver with TRI-STATE Outputs The 74VHCT244 is a high-speed CMOS octal buffer/line driver with 3-state outputs, manufactured by Fairchild Semiconductor. It is designed for bus-oriented applications and operates with a supply voltage range of 4.5V to 5.5V. The device features 8 non-inverting buffers with 3-state outputs, which are controlled by two output enable (OE) inputs. Each OE input controls four buffers. The 74VHCT244 is compatible with TTL levels and has a typical propagation delay of 5.5 ns. It is available in various package types, including SOIC, TSSOP, and PDIP. The device is characterized for operation from -40°C to 85°C.
