| Propagation Delay |
The Texas Instruments HC244 is a high-speed CMOS logic octal buffer/line driver with three-state outputs. Designed for high-current bus driving applications, this component offers significant power reduction compared to LSTTL logic ICs.
Key electrical characteristics include a typical propagation delay of 8ns at VCC = 5V and CL = 15pF. The HC types operate from 2V to 6V, while HCT types operate from 4.5V to 5.5V. Standard outputs provide a fanout of 10 LSTTL loads, and bus driver outputs offer a fanout of 15 LSTTL loads. Input logic compatibility is maintained with direct LSTTL compatibility for HCT types.
This device is available in various package types including SOIC, PDIP, CDIP, and TSSOP, with specified body dimensions for each. The operating temperature range spans from -55℃ to 125℃, making it suitable for a wide array of environmental conditions.
The HC244 features buffered inputs and high-current bus driver outputs, ensuring robust signal integrity in demanding applications. Its balanced propagation delay and transition times contribute to predictable performance.
