低压带3态输出的八路缓冲器/线路驱动器 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The LVT244 and LVTH244 are octal buffers and line drivers designed to be employed as memory address drivers, clock drivers and bus oriented transmitters or receivers which provide improved PC board density.
The LVTH244 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
Features
■Input and output interface capability to systems at 5V VCC
■Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs 74LVTH244, also available without bushold feature 74LVT244
■Live insertion/extraction permitted
■Power Up/Down high impedance provides glitch-free bus loading
■Outputs source/sink –32mA/+64mA
■Functionally compatible with the 74 series 244
■Latch-up performance exceeds 500mA
■ESD performance:
– Human-body model >2000V
– Machine model >200V
– Charged-device model >1000V
