SN64BCT244中文资料具有 TTL 兼容型 CMOS 输入和三态输出的 8 通道、4.5V 至 5.5V 缓冲器数据手册TI规格书

描述 Description

This octal buffer and line driver is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Taken together with the SN64BCT240 and SN64BCT241, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable () inputs, and complementary OE andinputs.The SN64BCT244 is organized as two 4-bit buffers/line drivers with separate output-enable () inputs. Whenis low, the device passes data from the A inputs to the Y outputs. Whenis high, the outputs are in the high-impedance state.The outputs are in a high-impedance state during power up and power down while the supply voltage is less than approximately 3 V. The SN64BCT244 is characterized for operation from -40°C to 85°C.
